Overcoming Speech Impediment: Symptoms to Treatment

There are many causes and solutions for impaired speech

• Types and Symptoms
• Speech Therapy
• Building Confidence

Speech impediments are conditions that can cause a variety of symptoms, such as an inability to understand language or speak with a stable sense of tone, speed, or fluidity. There are many different types of speech impediments, and they can begin during childhood or develop during adulthood.

Common causes include physical trauma, neurological disorders, or anxiety. If you or your child is experiencing signs of a speech impediment, you need to know that these conditions can be diagnosed and treated with professional speech therapy.

This article will discuss what you can do if you are concerned about a speech impediment and what you can expect during your diagnostic process and therapy.

Types and Symptoms of Speech Impediment

People can have speech problems due to developmental conditions that begin to show symptoms during early childhood or as a result of conditions that may occur during adulthood. 

The main classifications of speech impairment are aphasia (difficulty understanding or producing the correct words or phrases) or dysarthria (difficulty enunciating words).

Often, speech problems can be part of neurological or neurodevelopmental disorders that also cause other symptoms, such as multiple sclerosis (MS) or autism spectrum disorder .

There are several different symptoms of speech impediments, and you may experience one or more.

Can Symptoms Worsen?

Most speech disorders cause persistent symptoms and can temporarily get worse when you are tired, anxious, or sick.

Symptoms of dysarthria can include:

• Slurred speech
• Slow speech
• Choppy speech
• Hesitant speech
• Inability to control the volume of your speech
• Shaking or tremulous speech pattern
• Inability to pronounce certain sounds

Symptoms of aphasia may involve:

• Speech apraxia (difficulty coordinating speech)
• Difficulty understanding the meaning of what other people are saying
• Inability to use the correct words
• Inability to repeat words or phases
• Speech that has an irregular rhythm

You can have one or more of these speech patterns as part of your speech impediment, and their combination and frequency will help determine the type and cause of your speech problem.

Causes of Speech Impediment

The conditions that cause speech impediments can include developmental problems that are present from birth, neurological diseases such as Parkinson’s disease , or sudden neurological events, such as a stroke .

Some people can also experience temporary speech impairment due to anxiety, intoxication, medication side effects, postictal state (the time immediately after a seizure), or a change of consciousness.

Speech Impairment in Children

Children can have speech disorders associated with neurodevelopmental problems, which can interfere with speech development. Some childhood neurological or neurodevelopmental disorders may cause a regression (backsliding) of speech skills.

Common causes of childhood speech impediments include:

• Autism spectrum disorder : A neurodevelopmental disorder that affects social and interactive development
• Cerebral palsy :  A congenital (from birth) disorder that affects learning and control of physical movement
• Hearing loss : Can affect the way children hear and imitate speech
• Rett syndrome : A genetic neurodevelopmental condition that causes regression of physical and social skills beginning during the early school-age years.
• Adrenoleukodystrophy : A genetic disorder that causes a decline in motor and cognitive skills beginning during early childhood
• Childhood metabolic disorders : A group of conditions that affects the way children break down nutrients, often resulting in toxic damage to organs
• Brain tumor : A growth that may damage areas of the brain, including those that control speech or language
• Encephalitis : Brain inflammation or infection that may affect the way regions in the brain function
• Hydrocephalus : Excess fluid within the skull, which may develop after brain surgery and can cause brain damage

Do Childhood Speech Disorders Persist?

Speech disorders during childhood can have persistent effects throughout life. Therapy can often help improve speech skills.

Speech Impairment in Adulthood

Adult speech disorders develop due to conditions that damage the speech areas of the brain.

Common causes of adult speech impairment include:

• Head trauma 
• Nerve injury
• Throat tumor
• Stroke 
• Parkinson’s disease 
• Essential tremor
• Brain tumor
• Brain infection

Additionally, people may develop changes in speech with advancing age, even without a specific neurological cause. This can happen due to presbyphonia , which is a change in the volume and control of speech due to declining hormone levels and reduced elasticity and movement of the vocal cords.

Do Speech Disorders Resolve on Their Own?

Children and adults who have persistent speech disorders are unlikely to experience spontaneous improvement without therapy and should seek professional attention.

Steps to Treating Speech Impediment 

If you or your child has a speech impediment, your healthcare providers will work to diagnose the type of speech impediment as well as the underlying condition that caused it. Defining the cause and type of speech impediment will help determine your prognosis and treatment plan.

Sometimes the cause is known before symptoms begin, as is the case with trauma or MS. Impaired speech may first be a symptom of a condition, such as a stroke that causes aphasia as the primary symptom.

The diagnosis will include a comprehensive medical history, physical examination, and a thorough evaluation of speech and language. Diagnostic testing is directed by the medical history and clinical evaluation.

Diagnostic testing may include:

• Brain imaging , such as brain computerized tomography (CT) or magnetic residence imaging (MRI), if there’s concern about a disease process in the brain
• Swallowing evaluation if there’s concern about dysfunction of the muscles in the throat
• Electromyography (EMG) and nerve conduction studies (aka nerve conduction velocity, or NCV) if there’s concern about nerve and muscle damage
• Blood tests, which can help in diagnosing inflammatory disorders or infections

Your diagnostic tests will help pinpoint the cause of your speech problem. Your treatment will include specific therapy to help improve your speech, as well as medication or other interventions to treat the underlying disorder.

For example, if you are diagnosed with MS, you would likely receive disease-modifying therapy to help prevent MS progression. And if you are diagnosed with a brain tumor, you may need surgery, chemotherapy, or radiation to treat the tumor.

Therapy to Address Speech Impediment

Therapy for speech impairment is interactive and directed by a specialist who is experienced in treating speech problems . Sometimes, children receive speech therapy as part of a specialized learning program at school.

The duration and frequency of your speech therapy program depend on the underlying cause of your impediment, your improvement, and approval from your health insurance.

If you or your child has a serious speech problem, you may qualify for speech therapy. Working with your therapist can help you build confidence, particularly as you begin to see improvement.

Exercises during speech therapy may include:

• Pronouncing individual sounds, such as la la la or da da da
• Practicing pronunciation of words that you have trouble pronouncing
• Adjusting the rate or volume of your speech
• Mouth exercises
• Practicing language skills by naming objects or repeating what the therapist is saying

These therapies are meant to help achieve more fluent and understandable speech as well as an increased comfort level with speech and language.

Building Confidence With Speech Problems 

Some types of speech impairment might not qualify for therapy. If you have speech difficulties due to anxiety or a social phobia or if you don’t have access to therapy, you might benefit from activities that can help you practice your speech. 

You might consider one or more of the following for you or your child:

• Joining a local theater group
• Volunteering in a school or community activity that involves interaction with the public
• Signing up for a class that requires a significant amount of class participation
• Joining a support group for people who have problems with speech

Activities that you do on your own to improve your confidence with speaking can be most beneficial when you are in a non-judgmental and safe space.

Many different types of speech problems can affect children and adults. Some of these are congenital (present from birth), while others are acquired due to health conditions, medication side effects, substances, or mood and anxiety disorders. Because there are so many different types of speech problems, seeking a medical diagnosis so you can get the right therapy for your specific disorder is crucial.

What Is a Speech Impediment?

Types of speech disorders, speech impediment causes, how to fix a speech impediment, making a difference in speech disorders.

Communication is a cornerstone of human relationships. When an individual struggles to verbalize information, thoughts, and feelings, it can cause major barriers in personal, learning, and business interactions.

Speech impediments, or speech disorders, can lead to feelings of insecurity and frustration. They can also cause worry for family members and friends who don’t know how to help their loved ones express themselves.

Fortunately, there are a number of ways that speech disorders can be treated, and in many cases, cured. Health professionals in fields including speech-language pathology and audiology can work with patients to overcome communication disorders, and individuals and families can learn techniques to help.

Commonly referred to as a speech disorder, a speech impediment is a condition that impacts an individual’s ability to speak fluently, correctly, or with clear resonance or tone. Individuals with speech disorders have problems creating understandable sounds or forming words, leading to communication difficulties.

Some 7.7% of U.S. children — or 1 in 12 youths between the ages of 3 and 17 — have speech, voice, language, or swallowing disorders, according to the National Institute on Deafness and Other Communication Disorders (NIDCD). About 70 million people worldwide, including some 3 million Americans, experience stuttering difficulties, according to the Stuttering Foundation.

Common signs of a speech disorder

There are several symptoms and indicators that can point to a speech disorder.

• Unintelligible speech — A speech disorder may be present when others have difficulty understanding a person’s verbalizations.
• Omitted sounds — This symptom can include the omission of part of a word, such as saying “bo” instead of “boat,” and may include omission of consonants or syllables.
• Added sounds — This can involve adding extra sounds in a word, such as “buhlack” instead of “black,” or repeating sounds like “b-b-b-ball.”
• Substituted sounds — When sounds are substituted or distorted, such as saying “wabbit” instead of “rabbit,” it may indicate a speech disorder.
• Use of gestures — When individuals use gestures to communicate instead of words, a speech impediment may be the cause.
• Inappropriate pitch — This symptom is characterized by speaking with a strange pitch or volume.

In children, signs might also include a lack of babbling or making limited sounds. Symptoms may also include the incorrect use of specific sounds in words, according to the American Speech-Language-Hearing Association (ASHA). This may include the sounds p, m, b, w, and h among children aged 1-2, and k, f, g, d, n, and t for children aged 2-3.

Categories of Speech Impediments

Speech impediments can range from speech sound disorders (articulation and phonological disorders) to voice disorders. Speech sound disorders may be organic — resulting from a motor or sensory cause — or may be functional with no known cause. Voice disorders deal with physical problems that limit speech. The main categories of speech impediments include the following:

Fluency disorders occur when a patient has trouble with speech timing or rhythms. This can lead to hesitations, repetitions, or prolonged sounds. Fluency disorders include stuttering (repetition of sounds) or   (rapid or irregular rate of speech).

Resonance disorders are related to voice quality that is impacted by the shape of the nose, throat, and/or mouth. Examples of resonance disorders include hyponasality and cul-de-sac resonance.

Articulation disorders occur when a patient has difficulty producing speech sounds. These disorders may stem from physical or anatomical limitations such as muscular, neuromuscular, or skeletal support. Examples of articulation speech impairments include sound omissions, substitutions, and distortions.

Phonological disorders result in the misuse of certain speech sounds to form words. Conditions include fronting, stopping, and the omission of final consonants.

Voice disorders are the result of problems in the larynx that harm the quality or use of an individual’s voice. This can impact pitch, resonance, and loudness.

Impact of Speech Disorders

Some speech disorders have little impact on socialization and daily activities, but other conditions can make some tasks difficult for individuals. Following are a few of the impacts of speech impediments.

• Poor communication — Children may be unable to participate in certain learning activities, such as answering questions or reading out loud, due to communication difficulties. Adults may avoid work or social activities such as giving speeches or attending parties.
• Mental health and confidence — Speech disorders may cause children or adults to feel different from peers, leading to a lack of self-confidence and, potentially, self-isolation.

Resources on Speech Disorders

The following resources may help those who are seeking more information about speech impediments.

Children and adults can suffer from a variety of speech impairments that may have mild to severe impacts on their ability to communicate. The following 10 conditions are examples of specific types of speech disorders and voice disorders.

1. Stuttering

This condition is one of the most common speech disorders. Stuttering is the repetition of syllables or words, interruptions in speech, or prolonged use of a sound.

This organic speech disorder is a result of damage to the neural pathways that connect the brain to speech-producing muscles. This results in a person knowing what they want to say, but being unable to speak the words.

This consists of the lost ability to speak, understand, or write languages. It is common in stroke, brain tumor, or traumatic brain injury patients.

4. Dysarthria

This condition is an organic speech sound disorder that involves difficulty expressing certain noises. This may involve slurring, or poor pronunciation, and rhythm differences related to nerve or brain disorders.

The condition of lisping is the replacing of sounds in words, including “th” for “s.” Lisping is a functional speech impediment.

6. Hyponasality

This condition is a resonance disorder related to limited sound coming through the nose, causing a “stopped up” quality to speech.

7. Cul-de-sac resonance

This speech disorder is the result of blockage in the mouth, throat, or nose that results in quiet or muffled speech.

8. Orofacial myofunctional disorders

These conditions involve abnormal patterns of mouth and face movement. Conditions include tongue thrusting (fronting), where individuals push out their tongue while eating or talking.

9. Spasmodic Dysphonia

This condition is a voice disorder in which spasms in the vocal cords produce speech that is hoarse, strained, or jittery.

10. Other voice disorders

These conditions can include having a voice that sounds breathy, hoarse, or scratchy. Some disorders deal with vocal folds closing when they should open (paradoxical vocal fold movement) or the presence of polyps or nodules in the vocal folds.

Speech Disorders vs. Language Disorders

Speech disorders deal with difficulty in creating sounds due to articulation, fluency, phonology, and voice problems. These problems are typically related to physical, motor, sensory, neurological, or mental health issues.

Language disorders, on the other hand, occur when individuals have difficulty communicating the meaning of what they want to express. Common in children, these disorders may result in low vocabulary and difficulty saying complex sentences. Such a disorder may reflect difficulty in comprehending school lessons or adopting new words, or it may be related to a learning disability such as dyslexia. Language disorders can also involve receptive language difficulties, where individuals have trouble understanding the messages that others are trying to convey.

Speech disorders may be caused by a variety of factors related to physical features, neurological ailments, or mental health conditions. In children, they may be related to developmental issues or unknown causes and may go away naturally over time.

Physical and neurological issues. Speech impediment causes related to physical characteristics may include:

• Brain damage
• Nervous system damage
• Respiratory system damage
• Hearing difficulties
• Cancerous or noncancerous growths
• Muscle and bone problems such as dental issues or cleft palate

Mental health issues. Some speech disorders are related to clinical conditions such as:

• Autism spectrum disorder
• Down syndrome or other genetic syndromes
• Cerebral palsy or other neurological disorders
• Multiple sclerosis

Some speech impairments may also have to do with family history, such as when parents or siblings have experienced language or speech difficulties. Other causes may include premature birth, pregnancy complications, or delivery difficulties. Voice overuse and chronic coughs can also cause speech issues.

The most common way that speech disorders are treated involves seeking professional help. If patients and families feel that symptoms warrant therapy, health professionals can help determine how to fix a speech impediment. Early treatment is best to curb speech disorders, but impairments can also be treated later in life.

Professionals in the speech therapy field include speech-language pathologists (SLPs) . These practitioners assess, diagnose, and treat communication disorders including speech, language, social, cognitive, and swallowing disorders in both adults and children. They may have an SLP assistant to help with diagnostic and therapy activities.

Speech-language pathologists may also share a practice with audiologists and audiology assistants. Audiologists help identify and treat hearing, balance, and other auditory disorders.

How Are Speech Disorders Diagnosed?

Typically, a pediatrician, social worker, teacher, or other concerned party will recognize the symptoms of a speech disorder in children. These individuals, who frequently deal with speech and language conditions and are more familiar with symptoms, will recommend that parents have their child evaluated. Adults who struggle with speech problems may seek direct guidance from a physician or speech evaluation specialist.

When evaluating a patient for a potential speech impediment, a physician will:

• Conduct hearing and vision tests
• Evaluate patient records
• Observe patient symptoms

A speech-language pathologist will conduct an initial screening that might include:

• An evaluation of speech sounds in words and sentences
• An evaluation of oral motor function
• An orofacial examination
• An assessment of language comprehension

The initial screening might result in no action if speech symptoms are determined to be developmentally appropriate. If a disorder is suspected, the initial screening might result in a referral for a comprehensive speech sound assessment, comprehensive language assessment, audiology evaluation, or other medical services.

Initial assessments and more in-depth screenings might occur in a private speech therapy practice, rehabilitation center, school, childcare program, or early intervention center. For older adults, skilled nursing centers and nursing homes may assess patients for speech, hearing, and language disorders.

How Are Speech Impediments Treated?

Once an evaluation determines precisely what type of speech sound disorder is present, patients can begin treatment. Speech-language pathologists use a combination of therapy, exercise, and assistive devices to treat speech disorders.

Speech therapy might focus on motor production (articulation) or linguistic (phonological or language-based) elements of speech, according to ASHA. There are various types of speech therapy available to patients.

Contextual Utilization  — This therapeutic approach teaches methods for producing sounds consistently in different syllable-based contexts, such as phonemic or phonetic contexts. These methods are helpful for patients who produce sounds inconsistently.

Phonological Contrast — This approach focuses on improving speech through emphasis of phonemic contrasts that serve to differentiate words. Examples might include minimal opposition words (pot vs. spot) or maximal oppositions (mall vs. call). These therapy methods can help patients who use phonological error patterns.

Distinctive Feature — In this category of therapy, SLPs focus on elements that are missing in speech, such as articulation or nasality. This helps patients who substitute sounds by teaching them to distinguish target sounds from substituted sounds.

Core Vocabulary — This therapeutic approach involves practicing whole words that are commonly used in a specific patient’s communications. It is effective for patients with inconsistent sound production.

Metaphon — In this type of therapy, patients are taught to identify phonological language structures. The technique focuses on contrasting sound elements, such as loud vs. quiet, and helps patients with unintelligible speech issues.

Oral-Motor — This approach uses non-speech exercises to supplement sound therapies. This helps patients gain oral-motor strength and control to improve articulation.

Other methods professionals may use to help fix speech impediments include relaxation, breathing, muscle strengthening, and voice exercises. They may also recommend assistive devices, which may include:

• Radio transmission systems
• Personal amplifiers
• Picture boards
• Touch screens
• Text displays
• Speech-generating devices
• Hearing aids
• Cochlear implants

Speech Disorder Tips for Families

For parents who are concerned that their child might have a speech disorder — or who want to prevent the development of a disorder — there are a number of activities that can help. The following are tasks that parents can engage in on a regular basis to develop literacy and speech skills.

• Introducing new vocabulary words
• Reading picture and story books with various sounds and patterns
• Talking to children about objects and events
• Answering children’s questions during routine activities
• Encouraging drawing and scribbling
• Pointing to words while reading books
• Pointing out words and sentences in objects and signs

Parents can take the following steps to make sure that potential speech impediments are identified early on.

• Discussing concerns with physicians
• Asking for hearing, vision, and speech screenings from doctors
• Requesting special education assessments from school officials
• Requesting a referral to a speech-language pathologist, audiologist, or other specialist

When a child is engaged in speech therapy, speech-language pathologists will typically establish collaborative relationships with families, sharing information and encouraging parents to participate in therapy decisions and practices.

SLPs will work with patients and their families to set goals for therapy outcomes. In addition to therapy sessions, they may develop activities and exercises for families to work on at home. It is important that caregivers are encouraging and patient with children during therapy.

If identified during childhood, speech disorders can be corrected efficiently, giving children greater communication opportunities. If left untreated, speech impediments can cause a variety of problems in adulthood, and may be more difficult to diagnose and treat.

Parents, teachers, doctors, speech and language professionals, and other concerned parties all have unique responsibilities in recognizing and treating speech disorders. Through professional therapy, family engagement, positive encouragement and a strong support network, individuals with speech impediments can overcome their challenges and develop essential communication skills.

What Is a Speech Sound Disorder?

Halfpoint Images / Getty Images

Speech sound disorders are a blanket description for a child’s difficulty in learning, articulating, or using the sounds/sound patterns of their language. These difficulties are usually clear when compared to the communication abilities of children within the same age group.

Speech developmental disorders may indicate challenges with motor speech. Here, a child experiences difficulty moving the muscles necessary for speech production. This child may also face reduced coordination when attempting to speak.

Speech sound disorders are recognized where speech patterns do not correspond with the movements/gestures made when speaking.  

Speech impairments are a common early childhood occurrence—an estimated 2% to 13% of children live with these difficulties. Children with these disorders may struggle with reading and writing. This can interfere with their expected academic performance. Speech sound disorders are often confused with language conditions such as specific language impairment (SLI).

This article will examine the distinguishing features of this disorder. It will also review factors responsible for speech challenges, and the different ways they can manifest. Lastly, we’ll cover different treatment methods that make managing this disorder possible.

Symptoms of Speech Sound Disorder

A speech sound disorder may manifest in different ways. This usually depends on the factors responsible for the challenge, or how extreme it is.

There are different patterns of error that may signal a speech sound disorder. These include:

• Removing a sound from a word
• Including a sound in a word
• Replacing hard to pronounce sounds with an unsuitable alternative
• Difficulty pronouncing the same sound in different words (e.g., "pig" and "kit")
• Repeating sounds or words
• Lengthening words
• Pauses while speaking
• Tension when producing sounds
• Head jerks during speech
• Blinking while speaking
• Shame while speaking
• Changes in voice pitch
• Running out of breath while speaking

It’s important to note that children develop at different rates. This can reflect in the ease and ability to produce sounds. But where children repeatedly make sounds or statements that are difficult to understand, this could indicate a speech disorder.

Diagnosis of Speech Sound Disorders

For a correct diagnosis, a speech-language pathologist can determine whether or not a child has a speech-sound disorder.

This determination may be made in line with the requirements of the DSM-5 diagnostic criteria . These guidelines require that:

• The child experience persistent difficulty with sound production (this affects communication and speech comprehension)
• Symptoms of the disorder appear early during the child’s development stages
• This disorder limits communication. It affects social interactions, academic achievements, and job performance.
• The disorder is not caused by other conditions like a congenital disorder or an acquired condition like hearing loss . Hereditary disorders are, however, exempted. 

Causes of Speech Sound Disorders

There is no known cause of speech sound disorders. However, several risk factors may increase the odds of developing a speech challenge. These include:

• Gender : Male children are more likely to develop a speech sound disorder
• Family history : Children with family members living with speech disorders may acquire a similar challenge.
• Socioeconomics : Being raised in a low socioeconomic environment may contribute to the development of speech and literacy challenges.
• Pre- and post-natal challenges : Difficulties faced during pregnancy such as maternal infections and stressors may worsen the chances of speech disorders in a child. Likewise, delivery complications, premature birth, and low-birth-weight could lead to speech disorders.
• Disabilities : Down syndrome, autism , and other disabilities may be linked to speech-sound disorders.
• Physical challenges : Children with a cleft lip may experience speech sound difficulties.
• Brain damage : These disorders may also be caused by an infection or trauma to a child’s brain . This is seen in conditions like cerebral palsy where the muscles affecting speech are injured.

Types of Speech Sound Disorders

By the time a child turns three, at least half of what they say should be properly understood. By ages four and five, most sounds should be pronounced correctly—although, exceptions may arise when pronouncing “l”, “s”,”r”,”v”, and other similar sounds. By seven or eight, harder sounds should be properly pronounced. 

A child with a speech sound disorder will continue to struggle to pronounce words, even past the expected age. Difficulty with speech patterns may signal one of the following speech sound disorders:

This refers to interruptions while speaking. Stuttering is the most common form of disfluency. It is recognized for recurring breaks in the free flow of speech. After the age of four, a child with disfluency will still repeat words or phrases while speaking. This child may include extra words or sounds when communicating—they may also make words longer by stressing syllables.

This disorder may cause tension while speaking. Other times, head jerking or blinking may be observed with disfluency. 

Children with this disorder often feel frustrated when speaking, it may also cause embarrassment during interactions. 

Articulation Disorder

When a child is unable to properly produce sounds, this may be caused by inexact placement, speed, pressure, or movement from the lips, tongue, or throat.  

This usually signals an articulation disorder, where sounds like “r”, “l”, or “s” may be changed. In these cases, a child’s communication may be understood by only close family members.

Phonological Disorder

A phonological disorder is present where a child is unable to make the speech sounds expected of their age. Here, mistakes may be made when producing sounds. Other times, sounds like consonants may be omitted when speaking.  

Voice Disorder

Where a child is observed to have a raspy voice, this may be an early sign of a voice disorder. Other indicators include voice breaks, a change in pitch, or an excessively loud or soft voice.  

Children that run out of breath while speaking may also live with this disorder. Likewise, children may sound very nasally, or can appear to have inadequate air coming out of their nose if they have a voice disorder.

Childhood apraxia of speech occurs when a child lacks the proper motor skills for sound production. Children with this condition will find it difficult to plan and produce movements in the tongue, lips, jaw, and palate required for speech.  

Treatment of Speech Sound Disorder

Parents of children with speech sound disorders may feel at a loss for the next steps to take. To avoid further strain to the child, it’s important to avoid showing excessive concern.

Instead, listening patiently to their needs, letting them speak without completing their sentences, and showing usual love and care can go a long way.

For professional assistance, a speech-language pathologist can assist with improving a child’s communication. These pathologists will typically use oral motor exercises to enhance speech.

These oral exercises may also include nonspeech oral exercises such as blowing, oral massages and brushing, cheek puffing, whistleblowing, etc.

Nonspeech oral exercises help to strengthen weak mouth muscles, and can help with learning the common ways of communicating.

Parents and children with speech sound disorders may also join support groups for information and assistance with the condition.

A Word From Verywell

It can be frustrating to witness the challenges in communication. But while it's understandable to long for typical communication from a child—the differences caused by speech disorders can be managed with the right care and supervision. Speaking to a speech therapist, and showing love o children with speech disorders can be important first steps in overcoming these conditions.

10 Most Common Speech-Language Disorders & Impediments

As you get to know more about the field of speech-language pathology you’ll increasingly realize why SLPs are required to earn at least a master’s degree . This stuff is serious – and there’s nothing easy about it.

In 2016 the National Institute on Deafness and Other Communication Disorders reported that 7.7% of American children have been diagnosed with a speech or swallowing disorder. That comes out to nearly one in 12 children, and gets even bigger if you factor in adults.

Whether rooted in psycho-speech behavioral issues, muscular disorders, or brain damage, nearly all the diagnoses SLPs make fall within just 10 common categories…

Types of Speech Disorders & Impediments

Apraxia of speech (aos).

Apraxia of Speech (AOS) happens when the neural pathway between the brain and a person’s speech function (speech muscles) is lost or obscured. The person knows what they want to say – they can even write what they want to say on paper – however the brain is unable to send the correct messages so that speech muscles can articulate what they want to say, even though the speech muscles themselves work just fine. Many SLPs specialize in the treatment of Apraxia .

There are different levels of severity of AOS, ranging from mostly functional, to speech that is incoherent. And right now we know for certain it can be caused by brain damage, such as in an adult who has a stroke. This is called Acquired AOS.

However the scientific and medical community has been unable to detect brain damage – or even differences – in children who are born with this disorder, making the causes of Childhood AOS somewhat of a mystery. There is often a correlation present, with close family members suffering from learning or communication disorders, suggesting there may be a genetic link.

Mild cases might be harder to diagnose, especially in children where multiple unknown speech disorders may be present. Symptoms of mild forms of AOS are shared by a range of different speech disorders, and include mispronunciation of words and irregularities in tone, rhythm, or emphasis (prosody).

Stuttering – Stammering

Stuttering, also referred to as stammering, is so common that everyone knows what it sounds like and can easily recognize it. Everyone has probably had moments of stuttering at least once in their life. The National Institute on Deafness and Other Communication Disorders estimates that three million Americans stutter, and reports that of the up-to-10-percent of children who do stutter, three-quarters of them will outgrow it. It should not be confused with cluttering.

Most people don’t know that stuttering can also include non-verbal involuntary or semi-voluntary actions like blinking or abdominal tensing (tics). Speech language pathologists are trained to look for all the symptoms of stuttering , especially the non-verbal ones, and that is why an SLP is qualified to make a stuttering diagnosis.

The earliest this fluency disorder can become apparent is when a child is learning to talk. It may also surface later during childhood. Rarely if ever has it developed in adults, although many adults have kept a stutter from childhood.

Stuttering only becomes a problem when it has an impact on daily activities, or when it causes concern to parents or the child suffering from it. In some people, a stutter is triggered by certain events like talking on the phone. When people start to avoid specific activities so as not to trigger their stutter, this is a sure sign that the stutter has reached the level of a speech disorder.

The causes of stuttering are mostly a mystery. There is a correlation with family history indicating a genetic link. Another theory is that a stutter is a form of involuntary or semi-voluntary tic. Most studies of stuttering agree there are many factors involved.

Dysarthria is a symptom of nerve or muscle damage. It manifests itself as slurred speech, slowed speech, limited tongue, jaw, or lip movement, abnormal rhythm and pitch when speaking, changes in voice quality, difficulty articulating, labored speech, and other related symptoms.

It is caused by muscle damage, or nerve damage to the muscles involved in the process of speaking such as the diaphragm, lips, tongue, and vocal chords.

Because it is a symptom of nerve and/or muscle damage it can be caused by a wide range of phenomena that affect people of all ages. This can start during development in the womb or shortly after birth as a result of conditions like muscular dystrophy and cerebral palsy. In adults some of the most common causes of dysarthria are stroke, tumors, and MS.

A lay term, lisping can be recognized by anyone and is very common.

Speech language pathologists provide an extra level of expertise when treating patients with lisping disorders . They can make sure that a lisp is not being confused with another type of disorder such as apraxia, aphasia, impaired development of expressive language, or a speech impediment caused by hearing loss.

SLPs are also important in distinguishing between the five different types of lisps. Most laypersons can usually pick out the most common type, the interdental/dentalised lisp. This is when a speaker makes a “th” sound when trying to make the “s” sound. It is caused by the tongue reaching past or touching the front teeth.

Because lisps are functional speech disorders, SLPs can play a huge role in correcting these with results often being a complete elimination of the lisp. Treatment is particularly effective when implemented early, although adults can also benefit.

Experts recommend professional SLP intervention if a child has reached the age of four and still has an interdental/dentalised lisp. SLP intervention is recommended as soon as possible for all other types of lisps. Treatment includes pronunciation and annunciation coaching, re-teaching how a sound or word is supposed to be pronounced, practice in front of a mirror, and speech-muscle strengthening that can be as simple as drinking out of a straw.

Spasmodic Dysphonia

Spasmodic Dysphonia (SD) is a chronic long-term disorder that affects the voice. It is characterized by a spasming of the vocal chords when a person attempts to speak and results in a voice that can be described as shaky, hoarse, groaning, tight, or jittery. It can cause the emphasis of speech to vary considerably. Many SLPs specialize in the treatment of Spasmodic Dysphonia .

SLPs will most often encounter this disorder in adults, with the first symptoms usually occurring between the ages of 30 and 50. It can be caused by a range of things mostly related to aging, such as nervous system changes and muscle tone disorders.

It’s difficult to isolate vocal chord spasms as being responsible for a shaky or trembly voice, so diagnosing SD is a team effort for SLPs that also involves an ear, nose, and throat doctor (otolaryngologist) and a neurologist.

Have you ever heard people talking about how they are smart but also nervous in large groups of people, and then self-diagnose themselves as having Asperger’s? You might have heard a similar lay diagnosis for cluttering. This is an indication of how common this disorder is as well as how crucial SLPs are in making a proper cluttering diagnosis .

A fluency disorder, cluttering is characterized by a person’s speech being too rapid, too jerky, or both. To qualify as cluttering, the person’s speech must also have excessive amounts of “well,” “um,” “like,” “hmm,” or “so,” (speech disfluencies), an excessive exclusion or collapsing of syllables, or abnormal syllable stresses or rhythms.

The first symptoms of this disorder appear in childhood. Like other fluency disorders, SLPs can have a huge impact on improving or eliminating cluttering. Intervention is most effective early on in life, however adults can also benefit from working with an SLP.

Muteness – Selective Mutism

There are different kinds of mutism, and here we are talking about selective mutism. This used to be called elective mutism to emphasize its difference from disorders that caused mutism through damage to, or irregularities in, the speech process.

Selective mutism is when a person does not speak in some or most situations, however that person is physically capable of speaking. It most often occurs in children, and is commonly exemplified by a child speaking at home but not at school.

Selective mutism is related to psychology. It appears in children who are very shy, who have an anxiety disorder, or who are going through a period of social withdrawal or isolation. These psychological factors have their own origins and should be dealt with through counseling or another type of psychological intervention.

Diagnosing selective mutism involves a team of professionals including SLPs, pediatricians, psychologists, and psychiatrists. SLPs play an important role in this process because there are speech language disorders that can have the same effect as selective muteness – stuttering, aphasia, apraxia of speech, or dysarthria – and it’s important to eliminate these as possibilities.

And just because selective mutism is primarily a psychological phenomenon, that doesn’t mean SLPs can’t do anything. Quite the contrary.

The National Institute on Neurological Disorders and Stroke estimates that one million Americans have some form of aphasia.

Aphasia is a communication disorder caused by damage to the brain’s language capabilities. Aphasia differs from apraxia of speech and dysarthria in that it solely pertains to the brain’s speech and language center.

As such anyone can suffer from aphasia because brain damage can be caused by a number of factors. However SLPs are most likely to encounter aphasia in adults, especially those who have had a stroke. Other common causes of aphasia are brain tumors, traumatic brain injuries, and degenerative brain diseases.

In addition to neurologists, speech language pathologists have an important role in diagnosing aphasia. As an SLP you’ll assess factors such as a person’s reading and writing, functional communication, auditory comprehension, and verbal expression.

Speech Delay – Alalia

A speech delay, known to professionals as alalia, refers to the phenomenon when a child is not making normal attempts to verbally communicate. There can be a number of factors causing this to happen, and that’s why it’s critical for a speech language pathologist to be involved.

The are many potential reasons why a child would not be using age-appropriate communication. These can range anywhere from the child being a “late bloomer” – the child just takes a bit longer than average to speak – to the child having brain damage. It is the role of an SLP to go through a process of elimination, evaluating each possibility that could cause a speech delay, until an explanation is found.

Approaching a child with a speech delay starts by distinguishing among the two main categories an SLP will evaluate: speech and language.

Speech has a lot to do with the organs of speech – the tongue, mouth, and vocal chords – as well as the muscles and nerves that connect them with the brain. Disorders like apraxia of speech and dysarthria are two examples that affect the nerve connections and organs of speech. Other examples in this category could include a cleft palette or even hearing loss.

The other major category SLPs will evaluate is language. This relates more to the brain and can be affected by brain damage or developmental disorders like autism. There are many different types of brain damage that each manifest themselves differently, as well as developmental disorders, and the SLP will make evaluations for everything.

Issues Related to Autism

While the autism spectrum itself isn’t a speech disorder, it makes this list because the two go hand-in-hand more often than not.

The Centers for Disease Control and Prevention (CDC) reports that one out of every 68 children in our country have an autism spectrum disorder. And by definition, all children who have autism also have social communication problems.

Speech-language pathologists are often a critical voice on a team of professionals – also including pediatricians, occupational therapists, neurologists, developmental specialists, and physical therapists – who make an autism spectrum diagnosis .

In fact, the American Speech-Language Hearing Association reports that problems with communication are the first detectable signs of autism. That is why language disorders – specifically disordered verbal and nonverbal communication – are one of the primary diagnostic criteria for autism.

So what kinds of SLP disorders are you likely to encounter with someone on the autism spectrum?

A big one is apraxia of speech. A study that came out of Penn State in 2015 found that 64 percent of children who were diagnosed with autism also had childhood apraxia of speech.

This basic primer on the most common speech disorders offers little more than an interesting glimpse into the kind of issues that SLPs work with patients to resolve. But even knowing everything there is to know about communication science and speech disorders doesn’t tell the whole story of what this profession is all about. With every client in every therapy session, the goal is always to have the folks that come to you for help leave with a little more confidence than when they walked in the door that day. As a trusted SLP, you will build on those gains with every session, helping clients experience the joy and freedom that comes with the ability to express themselves freely. At the end of the day, this is what being an SLP is all about.

Rhotacism: A complete guide to this speech impediment

Remember when you were a child and spoke by making your “R’s” sound like “W’s” and everything thought it was cute? That’s known as rhotacism and some people live with it even as adults. What is rhotacism, what is it like in other languages, and what are its symptoms? What does it look like as a speech impediment and what are some examples? What are its causes? How does it affect the brain? Is it curable and how can it be fixed? This article will answer all your doubts about rhotacism. 

What is rhotacism?

Rhotacism is a speech impediment that is defined by the lack of ability, or difficulty in, pronouncing the sound R . Some speech pathologists, those who work with speech impediments may call this impediment de-rhotacization because the sounds don’t become rhotic, rather they lose their rhotic quality. It could also be called a residual R error.

It’s not such an uncommon phenomenon and actually also happens with the letter L , a phenomenon known as lambdacism . Sometimes people mistake these speech impediments for a lisp, of which they are not. Within the 2000-2001 school year, more than 700,000 students within the American public school system were categorized as having either a language impediment or a speech impediment. Ironically, all three speech impediments contain the troubled letter within them.

The word rhotacism comes from the New Latin rhotacism meaning peculiar or excessive use of [r]. The Latin word came from Ancient Greek word rhōtakismós which means to incorrectly use “rho” which is the equivalent of the Greek R. For language nerds, here’s a really great explanation of how the word came into being.

How does rhotacism work in different languages?

Rhotacism is, in theory , more common among people whose native language has a trilled R. For example, in Spanish the “rr” is a trilled R. Other languages with a trilled R include Bulgarian, Hungarian, Arabic, Finnish, Romanian, Indonesian, Russian , Italian, and most Swedish speakers. Some people might mock Asians, specifically Chinese, for not being able to pronounce the English word “broccoli” correctly- rather pronouncing it “browccoli”. This isn’t due to a rhotacism, however. It’s actually due to the fact that Mandarin (Chinese) words can have an “r” sound in the beginning of a word, but not in the middle or end of a word. This leads them to have issues in their phonotactics and creates an inability to pronounce the English “R” in the middle of words.

Symptoms of rhotacism

• Some people try to hide their impediment by avoiding words with R ’s in them.
• An overall inability to say R sounds
• Using trilled R’s or guttural R’s (such as the French R) when trying to pronounce the regular English R.

Rhotacism as a speech impediment

Using a strict classification, only about 5%-10% of the human population speaks in a completely normal way. Everyone else suffers from some type of speech disorder or another. For children of any language, the R sounds are usually the hardest to master and often end up being the last ones a child learns. That’s why baby talk if you think about it, doesn’t really use explicit or strong R sounds. In English, rhotacism often comes off as a W sound which is why “Roger Rabbit” sounds like “Woger Wabbit”. R is often more difficult because a child has to learn the different combination of the /r/ sounds, not just the letter itself, unlike other letters. For example, when it comes before and after vowel sounds. The combination of a vowel with the /r/ sound is called a phenome and in English, there are eight combinations of these:

–        The prevocalic R , such as “rain”

–        The RL , such as “girl”

–        The IRE, such as “tire”

–        The AR, such as “car”

–        The EAR , “such as “beer”

–        The OR , such as “seashore”

–        The ER , such as “butter”

–        The AIR , such as “software”

A speech impediment is a speech disorder , not a language disorder . Speech disorders are problems in being able to produce the sounds of speech whereas language disorders are problems with understanding and/or being able to use words. Language disorders, unlike speech disorders, have nothing to do with speech production.

Often what happens is that the person speaking isn’t tensing their tongue enough, or not moving their tongue correctly (up and backward depending on the dialect) which makes the W or “uh” sound come out. It may also be that the person is moving their lips instead of their tongue.

Examples of rhotacism

• Barry Kripke from the TV show The Big Bang Theory has both rhotacism and lambdacism- meaning he has issues pronouncing both his R ’s and his L ’s.
• The most famous of rhotacism would be Elmer Fudd from Looney Tunes . He pronounces the word “rabbit” [ˈɹ̠ʷæbɪ̈t] as “wabbit” [ˈwæbɪ̈t]
• In Monty Python’s Life of Brian , the 1979 film’s character Pilate suffers from rhotacism. In the film, people mock him for his inability to be understood easily.

Here’s a video with a woman who suffers from rhotacism. She explains how difficult it can be to have the speech impediment.

Causes of rhotacism

For many people, the causes of rhotacism are relatively unknown-, especially in adults. However, scientists theorize that the biggest cause is that the person grew up in an environment where they heard R ’s in a weird way, the shape of their mouths are different than normal, or their tongues and lips never learned how to produce the letter. In children, this could happen because the parents or adults around think the way the child talks (using baby talk) is cute and the child never actually learns how to produce it.

For one internet forum user, it has to do with how they learned the language , “I speak various languages, I pronounce the “R” normal in Dutch, French, and Spanish, but I have a rhotacism when speaking English. It’s the way I learnt it.”

For other people, speech issues are a secondary condition to an already existing, serious condition. Physically, it would be a cleft lip or a cleft palate. Neurologically, it could be a condition such as cerebral palsy. It may also be a tongue tie . Almost everyone has a stretch of skin that runs along the bottom of their tongue. If that skin is too tight and reaches the tip of the tongue, it can make pronouncing (and learning how to pronounce) R ’s and L ’s difficult. If the tongue tie isn’t fixed early on, it can be incredibly difficult to fix and learn how to pronounce later.

How the brain affects rhotacism

The brain affects rhotacism only for those who suffer from it not due to a physical impediment (such as a cleft palate). For some, this could happen because the brain doesn’t have the phonemic awareness and never actually learned what the letter R is supposed to sound like. This is common with kids whose parents spoke to them in “baby talk” and encouraged the child’s baby talk, too. This kind of behavior only strengthens a child’s inner concept that / R / is pronounced like “w” or “uh”.

Another reason could be that the brain connections simply don’t allow the lips or mouth to move in the way they need to in order to pronounce the R . This inability has little to do with physical incapabilities and more to do with mental ones. Some people with rhotacism have an issue with their oral-motor skills which means that there isn’t sufficient communication in the parts of the brain responsible for speech production.

Treatment for rhotacism

Is rhotacism curable.

It can have negative social effects- especially among younger children, such as bullying, which lowers self-esteem and can have a lasting effect. However, if the impediment is caught early enough on and is treated rather quickly, there is a good overall prognosis meaning it’s curable.

        However, some people never end up being able to properly pronounce that R and they end up substituting other sounds, such as the velar approximant (like w sounds) , the uvular approximant (also known as the “French R ”), and the uvular trill ( like the trilled R in Spanish).

How to fix rhotacism

Rhotacism is fixed by speech therapy . Before anything else, there needs to be an assessment from a Speech Language Pathologist (SLP) who will help decide if the problem can be fixed. If a child is involved, the SLP would predict if the child can outgrow the problem or not. After the diagnosis, a speech therapist will work with the person who suffers from the speech impediment by possibly having weekly visits with some homework and practice instructions. Therapy happens in spouts- a period of a few weeks and a break. There is a follow-up to see if there has been an improvement in pronunciation. In the U.S., children who are in school and have a speech disorder are placed in a special education program. Most school districts provide these children with speech therapy during school hours.

Another option, often used alongside speech therapy, is using a speech therapy hand-held tool that helps isolate the sound being pronounced badly and gives an image of the proper tongue placement to enable better pronunciation.

One study tested a handheld tactical tool (known as Speech Buddies) and the traditional speech therapy methods. The study found that students who used the hand-held tool (alongside speech therapy) improved 33% faster than those who used only the traditional speech therapy methods.

What Is a Lisp?

A lisp is a speech impediment that specifically relates to making the sounds associated with the letters S and Z. Lisps usually develop during childhood and often go away on their own. But some persist and require treatment.

What Causes a Lisp?

There are no known causes of lisps. Some people think that using a pacifier after a certain age may contribute to lisps. They believe prolonged pacifier use can strengthen the muscles of the tongue and lips, making lisps more likely. However, pacifier usage is not a factor in every child with a lisp. Additionally, each child who uses a pacifier doesn't get a lisp.

Other possible causes of lisps include:

• Tongue-tie — a condition where the tongue is tethered to the bottom of the mouth. This restricts its movement. Another name for a tongue-tie is ankyloglossia.
• Problems with jaw alignment.
• Simply having learned to say the sound incorrectly.

When Is Lisping a Concern?

Many young children have some kind of lisp as they learn to talk. It is one of the most common speech impediments. About 23% of speech-language pathologist clients have lisps. 

However, you may want to look into professional help if your child is still lisping after the age of 4 1/2. However, children as young as three years old can work on lisping with a speech-language pathologist.

Types of Lisps

There are four types of lisps:

• Frontal lisp. This lisp occurs when you push your tongue too far forward, making a "th" sound when trying to words with S or Z in them.
• Lateral lisp. Extra air slides over your tongue when making S and Z sounds, making it sound like there is excess saliva.
• Palatal lisp. You touch your tongue to the roof of your mouth when making S and Z sounds.
• Dental lisp. This lisp sounds like a frontal lisp. The difference is that instead of pushing the tongue through the teeth, it is pressing against the teeth.

Treatment for Lisps

Speech-language pathologists are specialists who can help children with lisps. They will evaluate what type of lisp your child has and then help them with it over a period of time. It can take anywhere from a few months to a few years to get rid of a lisp. If a child is older when they start working with a speech-language pathologist, it may take a longer time. 

Speech pathologists work with people who have lisps to help them recognize what their lisp sounds like and how to position their tongue in the correct place to make the sound. They do this by giving them exercises to do, like saying specific words or phrases with the sounds in them. Once your child has been working on their lisp for a while, your speech pathologist will engage them in conversation to challenge them to remember proper tongue placement.

If your child's lisp is from a tongue-tie, a doctor may recommend a simple in-office procedure called a frenotomy to reduce the tethering. They take a pair of scissors and snip the excess tissue holding the tongue down. If the tongue-tie is more severe, a surgery called a frenuloplasty may be required.

How to Find a Speech-Language Pathologist

Make sure that any speech-language pathologist you take your child to is licensed. In the US, each state has a different licensure process for speech-language therapists. They may also opt to get an additional certification from ASHA — the American Speech-Language-Hearing Association. Those who have this certification show they meet certain qualifications and follow ASHA's code of ethics. 

You should also make sure the speech-language therapist is child-friendly. You may be able to find this information on their website or by reading reviews online. In the session, you can also observe the interaction to make sure you are comfortable with how the therapist is treating your child.

After evaluation, the speech-language pathologist should be able to tell which type of lisp your child has. They should also be able to recommend exercises specific to that type of lisp to help your child. 

Other Types of Speech Impediments

Lisps are just one type of speech impediment. Other common speech impediments include:

• Lambdacism. Trouble saying the letter L. People with lambdacism often use the R sound as a substitute.
• Rhotacism. Difficulty with saying the letter R correctly.

The three most common speech impediments are sigmatism (lisping), lambdacism, and rhotacism. However, other people can also have trouble pronouncing the sounds associated with the letters K, G, T, D, and E. 

Home Remedies to Help Lisps

Whether or not your child sees a speech-language pathologist, there are things you can do at home to help your child's lisp, including:

• Treat allergies and sinus problems that may lead to lisping.
• Curb thumb sucking .
• Have your child drink through a straw to build strength.
• Encourage playtime with things like bubbles or horns.

Common Speech Impediments: Causes, Symptoms, Treatment, And Support

Speech impediments include a variety of both language and speech disorders, some of which can be addressed through  online speech therapy  with speech-language pathologists. They can arise because of heredity and genetics, developmental delays, or even damage to Broca’s area—the part of the brain that’s involved in language skills and speech skills. They may also be linked to other conditions like autism spectrum disorder, cerebral palsy, dyslexia, or even hearing loss. It depends on the type and the cause, but most speech impediments and speech impairments can be treated through speech therapy.

That said, recognizing when a speech impediment may be present can help you get yourself or your child the treatment and support they may need for improved academic and/or social functioning and self-confidence.

Common symptoms of a speech impediment

There are many different types of speech impediments a person can have, so the symptoms can vary. However, it’s important to understand what symptoms may indicate a speech disorder so that you can seek treatment if necessary. 

Symptoms of a speech disorder

• Elongating words
• Quiet or muffled speech
• Blinking frequently
• Distorted sounds while talking
• Frequent changes in pitch
• Poor voice quality
• Visible frustration when trying to communicate
• Overall difficulty communicating and expressing thoughts and ideas
• Inability to repeat words
• Inability to pronounce words the same way twice
• A phobia of speaking in public
• Speaking slowly and carefully
• Speech delay
• Frequent pauses when talking
• Limited vocabulary over several years, delayed language development

Some speech and language disorders are consistent with underlying mental health conditions such as autism. You can visit licensed health professionals or speech therapists to receive an accurate diagnosis and find out how to treat a speech impediment or language disorder, and its underlying cause, if applicable.

Categories of a speech disorder

Speech impediments or communication disorders can take many forms, from speech sound disorders to voice-related disorders. While speech sound disorders mostly result from sensory or motor causes, voice-related disorders deal with physical problems regarding speech. Read on for a list of some of the most common categories of speech impediments.

Voice disorders

Voice disorders  primarily arise due to issues regarding the health and structure of the larynx or the voice box. They can impact pitch, resonance, volume, and voice quality. Symptoms of a voice disorder may include having a hoarse, quivering, strained, choppy, or weak and whispery voice, which can make it difficult to produce speech sounds.

The root cause of these disorders can be either organic, like alterations to respiratory, laryngeal, or vocal tract mechanisms, or functional, like improper use of the voice. Some risk factors that may contribute to vocal health challenges include allergies, psychological stress, age, excessive alcohol or drug use, screaming, scarring from neck surgery, or even gastroesophageal reflux disease (GERD). Examples of voice disorders include laryngitis, vocal cord paralysis/weakness, polyps or nodes present on the vocal cords, leukoplakia, or muscle tension dysphonia.

Fluency disorders

A person may be diagnosed with a fluency disorder if they have trouble with speech timing and rhythm which makes it difficult to create a normal speech pattern. These disorders are characterized by interruptions in the typical flow of speaking, including abnormal repetitions, hesitation, and prolongations. Their cause is unknown, but it may be genetic. Symptoms can also be exacerbated by stress and anxiety. Stuttering is the most common example of fluency disorders. 

Symptoms of a fluency disorder may include dragging out syllables, speaking breathlessly, repetition of words, speaking slowly, and being tense while speaking. Secondary symptoms may include fidgeting, mumbling, saying “um” or “uh” often, not using certain problematic words, rearranging words in sentences, and anxiety around speaking. Treatment options vary depending on the specific disorder. With stuttering, for example, slowing down, practicing, using speech monitors, attending speech therapy, and receiving cognitive behavioral therapy (CBT) are all potential treatment options.

Articulation disorders and phonological disorders

Articulation and phonological disorders are two types of speech disorders classified as speech sound disorders that may impact communication. An articulation disorder includes speech that commonly exhibits errors such as substitution, omission, distortion, and/or addition (SODA). Although the actual causes of articulation disorders aren’t well understood, contributing factors may include brain injuries, a cleft palate/cleft lip, or nerve damage. Phonological disorders typically involve producing sounds correctly but using them in the wrong place and are more predictable than articulation errors. There may also be a genetic factor that contributes to both disorders and other families may be impacted as well. A licensed speech-language pathologist (SLP) can determine if an individual may have an articulation disorder or a phonological disorder. Ongoing speech therapy is typically the recommended treatment method.

Speech impediments versus language impairments

A speech impediment is typically characterized by difficulty creating sound due to factors like fluency disorders or other voice problems. These disorders may arise from underlying mental health issues, neurological problems, or physical factors or conditions impacting speech muscles.

Language impairments, on the other hand, are more about difficulty processing, reading, and writing and can be connected to an issue processing receptive language. They’re common in children, especially when they first start school. Language impairments relate to meaning, whereas speech impediments relate to sound. It’s also very common for a language impairment disorder to present alongside a learning disability like dyslexia.

An example of speech disorder: Apraxia

Apraxia of speech is a speech sound disorder that affects the pathways of the brain. It’s characterized by a person having difficulty expressing their thoughts accurately and consistently. It involves the brain being able to form the words and knowing exactly what to say, but the person then being unable to properly execute the required speech movements to deliver accurate sounds. In mild cases, a person will only have small limitations in their ability to form speech sounds. In severe cases, alternate communication methods may need to be used.

An SLP is the type of provider who can diagnose apraxia. To diagnose speech disorders, including both childhood apraxia (sometimes called verbal apraxia) and acquired apraxia, they may ask the individual to perform simple speech tasks like repeating a particular word several times or repeating a list of words that increase in length. Apraxia generally needs to be monitored by both parents and an SLP over time for an accurate diagnosis to be possible.

There are various treatment options for apraxia, the most common being one-on-one meetings with a speech pathologist. They’ll likely help you or your child build helpful strategies and skills to help strengthen problem areas and communicate more clearly. Some other treatment methods include improving speech intelligibility or using alternate forms of communication, like electronic speech or manual signs and gestures.

An example of communication disorder: Aphasia

The National Institute on Deafness and Other Communication Disorders describes aphasia as a communication disorder that results in a person’s inability to speak, write, and/or understand language. Like other communication disorders, it may occur because of damage to the portions of the brain that are involved in language, which is common in those who have experienced a stroke. It may also come on gradually in those who have a tumor or a progressive neurological disease like Alzheimer’s. Symptoms may include saying or writing sentences that don’t make sense, a reduction in a person’s ability to understand a conversation, and substituting certain sounds and words for others.

Brain injuries in patients with Aphasia

Since this disorder is usually caused by damage to parts of the brain, it will typically first be recognized in an MRI or CT scan that can confirm the presence of a brain injury. The extent and type of aphasia can generally only be determined by observing the affected part of the brain and determining how extensively it has been damaged, which is often done with the help of an SLP.

Treatment options for aphasia can be restorative (aimed at restoring impaired function) or compensatory (aimed at compensating for deficits).

An example of nervous system disorder: Dysarthria 

Dysarthria is usually caused by brain damage or facial paralysis that affects the muscles of the jaw, tongue, or throat, which may result in deficits in a person’s speech. It may also be caused by other conditions like Lou Gehrig’s disease, Parkinson’s, or a stroke. It’s considered a nervous system disorder, subclassified as a motor speech disorder. It’s commonly seen in those who already have other speech disorders, such as aphasia or apraxia. Symptoms of dysarthria include slurred speech, speaking too slowly, speaking too quickly, speaking very softly, being unable to move one’s lips or jaw, and having monotonous speech.

Exercises to counter muscle weakness

Dysarthria can be diagnosed by an expert in speech-language pathology through an exam and tests like MRI, CT, electromyography, or the Denver articulation screening examination. Treatment depends upon the severity and rate of progression of the disorder. Some potential examples include tactics like slowing down while talking, doing exercises to help strengthen jaw muscles, moving the lips and tongue more, and learning strategies for speaking more loudly. Hand gestures and speech machines may also help. 

Seek treatment if you’re having difficulty with verbal communication

It is important to treat speech disorders; the consequences of an untreated speech or language impediment can vary widely depending on the type, symptoms, and severity, as well as the age and life situation of the individual. In general, it’s usually helpful to seek professional advice on treating speech disorders as soon as you notice or suspect an impediment present in yours or your child’s speech. Especially for moderate to severe cases, some potential effects of leaving these common speech disorders untreated can include:

• Poor academic performance/dropping out of school
• Decrease in quality of life
• Social anxiety and an inability to connect with people
• Damaged relationships
• Social isolation
• Hospitalization

Support options and resources

Meeting with an SLP is usually the recommended first step for someone who believes they or their child may have a speech impediment. If you have a teenager with dyslexia, there are  resources for dyslexic teens  that can give supportive information about the condition. Healthcare providers may also provide helpful insights and ask about your family members’ history when it comes to speech and language-related issues as they can be hereditary.

Therapeutic support for speech impediments

While these professionals can help with the physical aspects of a variety of speech and language impediments, you or your child may also benefit from emotional support in relation to the mental health effects of having an impediment. A therapist may be able to provide this type of guidance. If your child is experiencing a speech impediment, a counselor may be able to work with them to process their feelings of frustration and learn healthy coping mechanisms for stress. They can help you manage the same feelings if you receive a speech or language impediment diagnosis, or may be able to support you in your journey of parenting a child with a speech or language impediment diagnosis.

In addition to support at home, teenagers with a diagnosed speech impairment or impediment can receive special education services at school. The Centers for Disease Control notes that under the Individuals with Disabilities Act (IDEA) and Section 504, schools must provide support and accommodations for students with speech disorders. For some children, support groups can provide outlets for social connections and advice for coping. 

Accessible healthcare options online

Meeting with a therapist in person is an option if there are providers in your area. That said, many people find it less intimidating or more comfortable to meet with a therapist virtually. For example, a teen who is experiencing a speech or language impediment may feel better interacting with a counselor through the online chat feature that virtual therapy platforms like TeenCounseling provide. It may allow them to express themselves more clearly than they could face-to-face or over the phone. Parents who need support in caring for a child with a speech or language impediment may find the availability and convenience of meeting with a therapist through an online therapy service like BetterHelp to be most beneficial. Research suggests that online and in-person therapy offer similar benefits for a variety of conditions, so you can choose the format that’s best for you.

Counselor reviews

See below for reviews of TeenCounseling therapists written by parents who sought help for their children through this service. 

“Kathleen has been good for my daughter to talk to. I am thankful for her to give my daughter someone else's perspective other than her parents. Thank you.”

“I love Ms. Jones. She doesn’t over-talk or judge you. She gives really good advice and if you're confused she knows how to break it down or explain whatever it is so you can understand. If you need to talk about anything, she’s always an open ear and responds quickly. Not only does she give you points from others' perspectives but she steps into yours so she can understand why certain things are the way they are. In my first session, I was nervous and I think she could tell. She’ll crack a joke every now and then to make me feel more comfortable. She’s just such a bundle of joy and a good counselor to have.”

Speech and language impediments can vary widely in terms of types, causes, symptoms, and severity. These are diagnosed by professionals in the field of speech and language pathology or by a medical doctor. A therapist can provide emotional support for those who are having difficulty coping with their own or their child’s diagnosis or other related challenges. 

What are the 3 speech impediments?

Speech impediments can manifest in a variety of ways. Three of the most common are listed below: 

• Voice disorders affect the tone, pitch, quality, and volume of a person’s voice. A person with a voice disorder may have difficulty speaking or being heard clearly by others. Voice disorders can be either functional or organic. Functional disorders occur due to improper use of the parts of the throat that produce speech, such as overuse of the voice leading to vocal fatigue. Organic voice disorders result from physical anatomical changes, such as nodules on the vocal cords. 
• Fluency disorders affect the rate, rhythm, and cadence of speech. Those with fluency disorders may speak in a disjointed, choppy, or prolonged fashion, making them difficult for others to understand clearly. While many types of fluency disorders exist, stuttering is likely the best-known. Speech often requires precise timing to convey a message accurately, which fluency disorders can disrupt. 
• Speech sound disorders are a broad category of disorders that interferes with a person’s ability to produce sounds and words correctly. Speech sound disorders can present very differently from person to person. Sometimes word sounds are omitted or added where not appropriate, and sometimes word sounds are distorted or substituted completely. A typical example of a speech sound disorder is the substitution of “r” for “w” in words like “rabbit” (becoming “wabbit”). Many children experience that substitution, but it does not become a disorder until the child does not outgrow it. 

Other types of disorders can cause problems with expressive communication or tongue-tie those experiencing them, such as developmental language disorder. Language disorders also cause concerns related to expressive communication, but the concerns are due to a lack of understanding of one or more components of language, not an inability to produce or use word sounds. 

What do you call a speech impediment?

Speech impediments are typically referred to as speech disorders . Speech refers to the ability to form speech sounds using the vocal cords, mouth, lips, and tongue. Speech also requires that a rhythm and cadence be maintained. Speech disorders indicate a problem producing intelligible speech; word sounds may be omitted or misplaced, the rhythm of the speech may be difficult to follow, or a person’s voice might be strangely pitched or too soft to hear clearly. 

It is important not to confuse speech disorders with language disorders . Language disorders arise due to difficulty understanding what words mean, how word sounds fit together, or how to use spoken language to communicate. Language problems may affect how a person speaks, but the root cause of the concern is linked to their understanding of language, not their ability to produce intelligible speech. 

How do I know if I have a speech impediment?

If you’re experiencing a sudden onset of impaired speech with no apparent cause, seek medical attention immediately. Strokes, traumatic brain injuries, and other serious medical conditions can cause sudden changes in speaking ability. Gradual changes in speaking ability may also indicate an underlying medical problem. If you’re concerned that your speaking ability has been gradually deteriorating, consider making an appointment with a healthcare provider in the near future. 

Most people with a speech disorder are diagnosed in childhood. Parents often identify speech-related concerns in early childhood based on their child’s speech patterns. The child’s pediatrician may also refer the child to a speech-language pathologist, a professional specializing in evaluating and treating speech disorders. If problems persist until the child is in school, teachers and other school officials might initiate a referral for an evaluation if they believe speech concerns are present. Children often receive speech and language therapy that resolves or improves their speech problems. 

Speech disorders also appear in adulthood, often due to injury or illness. It is also possible, although rare, for speech problems to be misdiagnosed or missed outright during a person’s childhood. In that case, the speech disorder may have been present since childhood and symptoms persisted into adulthood.

If you’re finding it difficult to communicate verbally with others, have an easily identifiable speech problem (like stuttering), or receive feedback that others have trouble understanding you, consider making an appointment with your doctor for an evaluation and referral to the appropriate healthcare providers. 

What are 5 causes of speech impairment?

Speech and language disorders can result from conditions that interfere with the development of perceptual, structural, motor, cognitive, or socioemotional functions. The cause of many speech disorders is unknown, but research has indicated several underlying factors that may be responsible: 

• Pre-existing genetic conditions, like Down’s syndrome or Fragile X syndrome. Evidence suggests that genes may play a role even if genetic abnormalities do not result in a diagnosable genetic condition. 
• Physical abnormalities, such as damage or improper development of the respiratory system, facial muscles, or cranial nerves. 
• Hearing problems, which can delay a child’s acquisition of speech. 
• Neurodevelopmental disorders, such as autism spectrum disorder, may interfere with speech development. There is also evidence to suggest that those with attention-deficit hyperactivity disorder may have a more challenging time acquiring speech skills. 
• Neurological conditions such as cerebral palsy. 

Mental health concerns can also cause problems communicating with others. For example, an underlying anxiety disorder may lead to selective mutism , wherein a child speaks only under certain circumstances. 

Is speech impediment a disability?

A speech-language disorder is considered a “ communication disability ” under the Americans with Disabilities Act (ADA). The ADA requires government and businesses to establish “effective communication” with people who have communication disabilities. Effective communication can be established in several ways. For those with a speech disorder, accommodation may be as simple as ensuring the person can get hold of writing materials if they need to express themselves quickly. In some cases, organizations may use a transliterator, or person trained to recognize unclear speech and repeat it clearly. 

Because speech disorders are known to lead to academic struggles in K-12 and higher education settings, they are categorized as a disability under the Individuals with Disabilities Education Improvement Act (IDEIA) . The IDEIA sets guidelines for all schools in the United States, public or not public, guaranteeing each child a right to accommodations and interventions for their speech disorder. 

Can I fix my speech impediment?

Whether or not a speech disorder can be completely eliminated depends heavily on individual factors. The cause of the disorder, its severity, and the type of speech dysfunction all play a role in determining whether a particular disorder can be completely resolved. While it is not possible to guarantee that a speech disorder can be “cured,” nearly all disorders are treatable, and improvement is likely possible. 

Can you treat a speech impediment?

Yes, many speech disorders are highly treatable. Most people receive treatment as children when most speech disorders become apparent. For children, speech-language pathologists will identify the specific speech disorder, search for an underlying cause, and design an intervention that targets that child’s speech problem. For example, a child who struggles with articulation errors and producing word sounds consistently may benefit from a contextual utilization approach . Contextual utilization leverages the fact that one sound is easier or more difficult to pronounce depending on which other sounds surround it. 

Speech disorders that emerge in adulthood may be more challenging to treat due to underlying factors, such as brain injury. Suppose an adult experiences a traumatic brain injury that affects their speaking ability. In that case, a speech-language pathologist may help them find alternative communication methods, such as using a computer. They may also help them directly restore some of their speaking ability by leading them through exercises that improve nerve function and muscle control.  

Is a speech impediment mental?

Speech disorders can be caused by various factors, many of which have nothing to do with the brain. However, there is a relationship between psychiatric mental health concerns and difficulty with spoken communication . Although researchers are still unsure of the exact cause, studies have identified a significant link between speech disorders and mental health disorders like schizophrenia, bipolar disorder, and major depression. 

Neurodevelopmental disorders, such as autism spectrum disorder and attention-deficit hyperactivity disorder, are also associated with an increased risk of developing a speech disorder. Although the link between neurodevelopmental disorders and speech disorders is not fully understood, evidence suggests that treating the speech disorder is still possible. 

Finally, speech disorders can also be caused by illness or injury in the brain, such as cancer, an infection, or traumatic brain injury. Although these are not considered mental or developmental disorders, they may affect brain function and mental acuity. Speaking is a complex process, and there are many ways it can be affected. 

Is autism a speech impediment?

Autism spectrum disorder is not a speech disorder, but it is heavily associated with communication problems. Those on the autism spectrum often use repetitive or rigid language and may not follow communication norms. They may repeat phrases continuously, use a modified tone of voice, or introduce information that has little to do with the conversation at hand. 

Those on the autism spectrum are often able to form word sounds properly. The communication deficits of autism spectrum disorder are more closely related to language disorders than speech disorders. Speech disorders are associated with difficulty producing or using word sounds correctly, whereas language disorders are associated with a lack of understanding of one or more language components.

Autism spectrum disorder is also characterized by difficulties using pragmatic communication, or communication that is appropriate to a specific social situation. Although not a disorder of speech, a limited ability to recognize the socioemotional content of speech can significantly impact interpersonal communication and social interactions.

Assistive Devices for People with Hearing, Voice, Speech, or Language Disorders

On this page:

What are assistive devices?

What types of assistive devices are available, what types of assistive listening devices are available, what types of augmentative and alternative communication devices are available for communicating face-to-face, what augmentative and alternative communication devices are available for communicating by telephone, what types of alerting devices are available, what research is being conducted on assistive technology, where can i get more information.

The terms assistive device or assistive technology can refer to any device that helps a person with hearing loss or a voice, speech, or language disorder to communicate. These terms often refer to devices that help a person to hear and understand what is being said more clearly or to express thoughts more easily. With the development of digital and wireless technologies, more and more devices are becoming available to help people with hearing, voice, speech, and language disorders communicate more meaningfully and participate more fully in their daily lives.

Health professionals use a variety of names to describe assistive devices:

• Assistive listening devices (ALDs) help amplify the sounds you want to hear, especially where there’s a lot of background noise. ALDs can be used with a hearing aid or cochlear implant to help a wearer hear certain sounds better.
• Augmentative and alternative communication (AAC) devices help people with communication disorders to express themselves. These devices can range from a simple picture board to a computer program that synthesizes speech from text.
• Alerting devices connect to a doorbell, telephone, or alarm that emits a loud sound or blinking light to let someone with hearing loss know that an event is taking place.

Several types of ALDs are available to improve sound transmission for people with hearing loss. Some are designed for large facilities such as classrooms, theaters, places of worship, and airports. Other types are intended for personal use in small settings and for one-on-one conversations. All can be used with or without hearing aids or a cochlear implant. ALD systems for large facilities include hearing loop systems, frequency-modulated (FM) systems, and infrared systems.

This logo informs people that a public area is looped. Source: HearingLoop.org

Hearing loop (or induction loop) systems use electromagnetic energy to transmit sound. A hearing loop system involves four parts:

• A sound source, such as a public address system, microphone, or home TV or telephone
• An amplifier
• A thin loop of wire that encircles a room or branches out beneath carpeting
• A receiver worn in the ears or as a headset

Amplified sound travels through the loop and creates an electromagnetic field that is picked up directly by a hearing loop receiver or a telecoil (see sidebar), a miniature wireless receiver that is built into many hearing aids and cochlear implants. To pick up the signal, a listener must be wearing the receiver and be within or near the loop. Because the sound is picked up directly by the receiver, the sound is much clearer, without as much of the competing background noise associated with many listening environments. Some loop systems are portable, making it possible for people with hearing loss to improve their listening environments, as needed, as they proceed with their daily activities. A hearing loop can be connected to a public address system, a television, or any other audio source. For those who don’t have hearing aids with embedded telecoils, portable loop receivers are also available.

What’s a telecoil?

A telecoil, also called a t-coil, is a coil of wire that is installed inside many hearing aids and cochlear implants to act as a miniature wireless receiver. It was originally designed to make sounds clearer to a listener over the telephone. It also is used with a variety of other assistive listening devices, such as hearing loop (or induction loop) systems, FM systems, infrared systems, and personal amplifiers.

The telecoil works by receiving an electromagnetic signal from the hearing loop and then turning it back into sound within the hearing aid or cochlear implant. This process eliminates much of the distracting background noise and delivers sound customized for one’s own need. For people who are hard-of-hearing who do not have a telecoil-equipped hearing aid or cochlear implant, loop receivers with headsets can provide similar benefits but without the customized or “corrected sound” feature that matches one’s hearing loss pattern.

Many cochlear implants have a telecoil built into the sound processor, or can use an external telecoil accessory with both hearing aid compatible telephones and public loop systems. A simple switch or programming maneuver performed by the user activates this function.

See the NIDCD fact sheet Hearing Aids for more information.

FM systems use radio signals to transmit amplified sounds. They are often used in classrooms, where the instructor wears a small microphone connected to a transmitter and the student wears the receiver, which is tuned to a specific frequency, or channel. People who have a telecoil inside their hearing aid or cochlear implant may also wear a wire around the neck (called a neckloop) or behind their aid or implant (called a silhouette inductor) to convert the signal into magnetic signals that can be picked up directly by the telecoil. FM systems can transmit signals up to 300 feet and are able to be used in many public places. However, because radio signals are able to penetrate walls, listeners in one room may need to listen to a different channel than those in another room to avoid receiving mixed signals. Personal FM systems operate in the same way as larger scale systems and can be used to help people with hearing loss to follow one-on-one conversations.

Infrared systems use infrared light to transmit sound. A transmitter converts sound into a light signal and beams it to a receiver that is worn by a listener. The receiver decodes the infrared signal back to sound. As with FM systems, people whose hearing aids or cochlear implants have a telecoil may also wear a neckloop or silhouette inductor to convert the infrared signal into a magnetic signal, which can be picked up through their telecoil. Unlike induction loop or FM systems, the infrared signal cannot pass through walls, making it particularly useful in courtrooms, where confidential information is often discussed, and in buildings where competing signals can be a problem, such as classrooms or movie theaters. However, infrared systems cannot be used in environments with too many competing light sources, such as outdoors or in strongly lit rooms.

Personal amplifiers are useful in places in which the above systems are unavailable or when watching TV, being outdoors, or traveling in a car. About the size of a cell phone, these devices increase sound levels and reduce background noise for a listener. Some have directional microphones that can be angled toward a speaker or other source of sound. As with other ALDs, the amplified sound can be picked up by a receiver that the listener is wearing, either as a headset or as earbuds.

The simplest AAC device is a picture board or touch screen that uses pictures or symbols of typical items and activities that make up a person’s daily life. For example, a person might touch the image of a glass to ask for a drink. Many picture boards can be customized and expanded based on a person’s age, education, occupation, and interests.

Keyboards, touch screens, and sometimes a person’s limited speech may be used to communicate desired words. Some devices employ a text display. The display panel typically faces outward so that two people can exchange information while facing each other. Spelling and word prediction software can make it faster and easier to enter information.

Speech-generating devices go one step further by translating words or pictures into speech. Some models allow users to choose from several different voices, such as male or female, child or adult, and even some regional accents. Some devices employ a vocabulary of prerecorded words while others have an unlimited vocabulary, synthesizing speech as words are typed in. Software programs that convert personal computers into speaking devices are also available.

For many years, people with hearing loss have used text telephone or telecommunications devices, called TTY or TDD machines, to communicate by phone. This same technology also benefits people with speech difficulties. A TTY machine consists of a typewriter keyboard that displays typed conversations onto a readout panel or printed on paper. Callers will either type messages to each other over the system or, if a call recipient does not have a TTY machine, use the national toll-free telecommunications relay service at 711 to communicate. (See Telecommunications Relay Services for more information.) Through the relay service, a communications assistant serves as a bridge between two callers, reading typed messages aloud to the person with hearing while transcribing what’s spoken into type for the person with hearing loss.

With today’s new electronic communication devices, however, TTY machines have almost become a thing of the past. People can place phone calls through the telecommunications relay service using almost any device with a keypad, including a laptop, personal digital assistant, and cell phone. Text messaging has also become a popular method of communication, skipping the relay service altogether.

Another system uses voice recognition software and an extensive library of video clips depicting American Sign Language to translate a signer’s words into text or computer-generated speech in real time. It is also able to translate spoken words back into sign language or text.

Finally, for people with mild to moderate hearing loss, captioned telephones allow you to carry on a spoken conversation, while providing a transcript of the other person’s words on a readout panel or computer screen as back-up.

Alerting or alarm devices use sound, light, vibrations, or a combination of these techniques to let someone know when a particular event is occurring. Clocks and wake-up alarm systems allow a person to choose to wake up to flashing lights, horns, or a gentle shaking.

Visual alert signalers monitor a variety of household devices and other sounds, such as doorbells and telephones. When the phone rings, the visual alert signaler will be activated and will vibrate or flash a light to let people know. In addition, remote receivers placed around the house can alert a person from any room. Portable vibrating pagers can let parents and caretakers know when a baby is crying. Some baby monitoring devices analyze a baby’s cry and light up a picture to indicate if the baby sounds hungry, bored, or sleepy.

The National Institute on Deafness and Other Communication Disorders (NIDCD) funds research into several areas of assistive technology, such as those described below.

• Improved devices for people with hearing loss NIDCD-funded researchers are developing devices that help people with varying degrees of hearing loss communicate with others. One team has developed a portable device in which two or more users type messages to each other that can be displayed simultaneously in real time. Another team is designing an ALD that amplifies and enhances speech for a group of individuals who are conversing in a noisy environment.
• More natural synthesized speech NIDCD-sponsored scientists are also developing a personalized text-to-speech synthesis system that synthesizes speech that is more intelligible and natural sounding to be incorporated in speech-generating devices. Individuals who are at risk of losing their speaking ability can prerecord their own speech, which is then converted into their personal synthetic voice.
• Brain–computer interface research A relatively new and exciting area of study is called brain–computer interface research. NIDCD-funded scientists are studying how neural signals in a person’s brain can be translated by a computer to help someone communicate. For example, people with amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) or brainstem stroke lose their ability to move their arms, legs, or body. They can also become locked-in, where they are not able to express words, even though they are able to think and reason normally. By implanting electrodes on the brain’s motor cortex, some researchers are studying how a person who is locked-in can control communication software and type out words simply by imagining the movement of his or her hand. Other researchers are attempting to develop a prosthetic device that will be able to translate a person’s thoughts into synthesized words and sentences. Another group is developing a wireless device that monitors brain activity that is triggered by visual stimulation. In this way, people who are locked-in can call for help during an emergency by staring at a designated spot on the device

Understanding Speech Impediments in Children

How do you know if your child has a speech impediment? Speech impediments in children are more common than you might think. They are a type of communication disorder where “normal” speech is disrupted. The disruption can include a lisp, stuttering, stammering, mis-articulation of certain sounds and more. Another commonly used phrase for speech impediments in children is speech disorder. Often, the causes of a speech impediment are unknown. However, sometimes there are physical impairments such as cleft palate or neurological disorders such as traumatic brain injury that may be the cause of the speech impairment. We have listed below five of the most common types of speech impediments in children and a general description of each. Of course, if you suspect your child may have a speech impairment of any kind, we encourage you to visit your pediatrician or hire a Speech Therapist for more information.

Common Types of Speech Impediments in Children

• Apraxia of Speech: Apraxia involves the inconsistent producing and rearranging of speech sounds. For instance potato may become totapo. This disorder may be developmental, where the symptoms have been evident from birth, or acquired. Acquired apraxia of speech generally results from a physical impairment such as injury or stroke.
• Speech Sound Disorder: A speech sound disorder involves difficulty producing certain sounds. The sounds could include /r/, /s/, /l/,/th/, /g/, /ch/ and /sh/. For example, a child may say “wabbit” instead of “rabbit”.  Speech sound disorders are divided into two categories of speech disorders. The first is a Phonetic disorder or articulation disorder which involves the child having difficulty in learning to produce certain sounds physically. The second speech sound disorder is a Phonemic disorder. This type of speech impediment involves the child having difficulty learning the sound distinctions of a language. Luckily, this common speech impediment in children is often easily corrected. Tongue placement tools or working with a Speech Therapist can really help your child.
• Cluttering: Cluttering is a speech disorder characterized by a rapid rate making speech difficult to understand, which in turn affects the person’s fluency. This can happen if the person has a tendency to speak really fast. This can also result when an individual continues to repeat themselves in order to try to make them understood. Cluttering is also referred to as fluency disorder.
• Lisp : A lisp is a speech impediment in children who are struggling to produce the /s/ sound clearly. A frontal lisp is when a child pushes his tongue too far forward in the mouth. A lateral lisp produces a “slushy” sound because too much air is escaping out the sides of a child’s mouth.

We have identified only five of the most common types of speech impediments in children. There are a number of other speech disorders beyond what we have listed. Please refer to our free eBook  for additional information. The good news is that with consistent speech therapy and early intervention, speech impediments in children can be overcome.

Speech therapy exercises with speech blubs, apraxia of speech, speech sound disorder, specific language impairment, language-based learning disabilities, key takeaways about speech impediments.

A speech impediment relates to the way an individual produces or articulates specific sounds. One example of this is stuttering. Under the umbrella of a speech impairment lies several different types of disorders with which a child or adult can be diagnosed.

A language impairment involves understanding and sharing thoughts and ideas. For example, this person may not have adequate or “age-appropriate” vocabulary and grammar skills. Again, there are several different language disorders that fall under this category that will be addressed in this blog.

3 Types of Speech Disorders

Apraxia of speech is a neurogenic (starts in the nervous system) communication disorder that involves the planning system for speech.

Individuals with Apraxia know what they want to say, but there is a disconnect in the part of the brain that tells a specific muscle to move. When someone is diagnosed with  apraxia of speech , they may have signs of groping, which is where the mouth searches for the position to create the sound.

When this occurs, it affects how long or short the sounds are, and could lead to odd pitch or volume issues and to sounds being distorted or substituted. A tell-tale sign of someone who has apraxia is that they lose the ability to produce sounds that they previously could say.

For instance, if you ask a child to say the word “dog,” which they do successfully and then ask them to say the same word again 10 minutes later, they will not be able to do it. 

Speech sound disorders may be of two varieties: articulation (the production of sounds) or phonological processes (sound patterns).

An articulation disorder  may take the form of substitution, omission, addition, or distortion of normal speech sounds.

Phonological process disorders  may involve more systematic difficulties with the production of particular types of sounds, such as those made in the back of the mouth, like “k” and “g” (ASHA 2018).

Educating a child on the appropriate ways to produce a speech sound and encouraging the child to practice this articulation over time may produce natural speech.

Stuttering  is a disruption in the fluency of an individual’s speech, which begins in childhood and may persist over a lifetime.

Stuttering is a form of disfluency (an inability to produce fluent speech). Disfluency becomes a problem because it impedes successful communication between two parties. Disfluencies may be due to unwanted repetitions of sounds (e.g., “I-I-I want ice cream”), or the extension of speech sounds (e.g., “S——tart the wash”), syllables (e.g., “Na-na-na nasty”), or words (e.g., “go-go-go to the store”). Disfluencies also incorporate unintentional pauses in speech, in which the individual is unable to produce speech sounds (ASHA 2016).

Unfortunately, the cause of stuttering is unknown, which makes it more difficult to treat. Treatment can vary from person to person depending on the severity and type of stuttering that is occurring.

3 Types of Language Disorders

Specific Learning Impairment (SLI) is diagnosed when a child’s language is not developing as rapidly or as typically as other children. In order for a child to be diagnosed with SLI, they cannot have Autism Spectrum Disorder, Apraxia, hearing loss, or an abnormality of the speech mechanisms. If those disorders are present, they do not have SLI and are exhibiting speech patterns typical of those diagnoses. Usually, the first indication of SLI is that the child is later than usual in starting to speak and subsequently is delayed in putting words together to form sentences.  Spoken language  may be immature. In many children with SLI, understanding of  language , or  receptive  language, is also impaired, though this may not be obvious unless the child is given a formal assessment. This diagnosis is reserved for children whose language difficulties persist into school age, not for children who are speech delayed and eventually catch up to their peers. 

Aphasia  is an inability to comprehend or formulate language because of damage to specific brain regions.

The major causes are a cerebral vascular accident (stroke), or head trauma, but aphasia can also be the result of brain tumors, brain infections, or neurodegenerative diseases such as dementia (ASHA 2017).

The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write; intelligence, however, is unaffected. Any person of any age can develop aphasia, given that it is often caused by a traumatic injury. However, people who are middle-aged and older are the most likely to experience the problem. 

Language-based learning disabilities occur in children who are falling behind their same-aged peers. These children will have difficulties with spelling, reading, and/or writing, but have normal intelligence levels. This is a common source of academic struggles in young children and can often be misdiagnosed or missed in typical assessments.

The key to supporting students with LBLD is knowing how to adjust curriculum and instruction to ensure they develop  proficient language and literacy skills . Most individuals with LBLD need instruction that is specialized, explicit, structured, and multisensory, as well as ongoing, guided practice aimed at remediating their specific areas of weakness.

There are a lot of speech and language impediments that can occur in children and adults. This blog only scratches the surface of these disorders, so please stay tuned and check out Speech Blubs regularly for more in-depth blogs regarding these subjects.

They Spouted Hate Online. Then They Were Arrested.

As hundreds of people appear in court for their role in recent anti-immigrant riots in Britain, several are accused of fueling disorder through online posts, raising questions about the limits of free speech.

Reporting from London

A 53-year-old woman from northwest England was jailed for 15 months after posting on Facebook that a mosque should be blown up “with the adults inside.” A 45-year-old man was sentenced to 20 months for goading his online followers to torch a hotel that houses refugees. A 55-year-old woman was questioned by the police for a viral post that wrongly identified the suspect in a deadly knife attack at a children’s dance class.

These and other people are accused of being “keyboard warriors,” in the words of one British judge, exploiting social media to stir up the anti-immigrant riots that exploded after the suspect was arrested in the fatal stabbings of three young girls at the dance class, in the town of Southport. Their cases have now become examples in a politically charged debate over the limits of free speech in Britain.

With the courts handing down harsh sentences to hundreds who took part in the violent unrest, and calls for the government to strengthen regulation of online content, some argue that the authorities risk going too far. Not only are judges locking up far-right rioters , these critics say, but they are also opening the door to a broader crackdown on speech.

The noisiest critiques have come from Elon Musk, the billionaire owner of X, once known as Twitter. After far-right groups used his platform to spread disinformation about the attack and foment the violent disorder that followed, Mr. Musk waded into the debate, claiming that civil war “is inevitable” in Britain and attacking Prime Minister Keir Starmer.

“The U.K. is turning into a police state,” Mr. Musk posted on Monday, referring to an emergency plan activated by the government to ease pressure on chronically overcrowded jails, under which defendants can be held longer in police cells until space opens in prisons.

What to Know About Robert F. Kennedy Jr.’s Vocal Disorder Spasmodic Dysphonia

Robert F. Kennedy Jr. was diagnosed with spasmodic dysphonia at age 42, causing his voice to become raspy

Robert F. Kennedy Jr. has an extremely hoarse voice.

The 70-year-old previously shared that his now signature raspiness is the result of a rare neurological disorder called spasmodic dysphonia, which he was diagnosed with in 1996.

“I had a very very strong voice until I was 46 years old. It was unusually strong,” he said during a news broadcast in June 2023. “It makes my voice tremble. At the time, I didn’t know what was wrong with it. But when I would go on TV, people would write me letters and say, ‘You have spasmodic dysphonia.’”

“I cannot listen to myself on TV,” he said at the time. “I will never listen to this broadcast, and I won’t listen to any. So I feel sorry for you guys having to listen to me.”

Spasmodic dysphonia is a chronic neurological speech disorder that results in involuntary spasms of the muscles that open or close the vocal folds. It causes the voice to suddenly sound breathy, strained, shaky or hoarse as if a person has lost their voice, according to the Cleveland Clinic .

The disorder affects about 50,000 people in the United States and is more likely to impact women more than men. Although spasmodic dysphonia can start at any age, it typically occurs between ages 30 and 60.

The exact cause of spasmodic dysphonia is unknown but most cases result from a trigger in the brain and nervous system. 

According to the National Institutes of Health , spasmodic dysphonia may be hereditary. Although a specific gene for the disorder has not been identified, a mutation in a gene that causes other forms of dystonia has also been associated with spasmodic dysphonia.

There is no cure for spasmodic dysphonia and it is a lifelong condition. However, there are treatments to minimize these vocal cord spasms and help alleviate symptoms.

Botox injections — which is required every three to six months — and speech therapy are common forms of treatment. There are also more invasive treatment options, including a thyroplasty surgery or selective laryngeal adductor denervation-reinnervation (SLAD-R) surgery.

Last year, Kennedy said during an interview that he recently underwent a surgery in Japan to treat his disorder. Noting that the procedure is not yet available in the United States, he said he had titanium implanted between his vocal cords to keep them from constricting.

“I’ve done a lot of functional medicine stuff and I’ve worked with a chiropractor and I’ve worked with a lot of other people and my voice now is getting better and better,” he said. “And I think part of it was the surgery but also part of it was the therapies I’m doing now.”
