Speech-language pathologists commonly treat 10 categories of communication disorders including apraxia of speech, stuttering, dysarthria, lisps, spasmodic dysphonia, cluttering, selective mutism, aphasia, speech delays, and autism-related communication issues. According to the National Institute on Deafness and Other Communication Disorders, approximately 8 to 9% of American children are diagnosed with speech or swallowing disorders.

As you explore the field of speech-language pathology, you’ll quickly discover why SLPs are required to earn at least a master’s degree. The scope and complexity of communication disorders demand extensive clinical training and specialized knowledge. These aren’t simple pronunciation issues that resolve on their own.
Communication disorders affect millions of Americans across all age groups. The National Institute on Deafness and Other Communication Disorders reports that approximately 8 to 9% of American children have been diagnosed with speech or swallowing disorders. When you factor in adults with acquired disorders from strokes, brain injuries, or degenerative diseases, the numbers grow significantly larger.
Whether rooted in neurological differences, muscular disorders, brain damage, or developmental factors, the vast majority of disorders SLPs diagnose and treat fall within 10 common categories. Understanding these core disorder types forms the foundation of your clinical education and prepares you for the diverse cases you’ll encounter throughout your career.
10 Common Speech Disorders Speech-Language Pathologists Treat
1. Apraxia of Speech (AOS)
Apraxia of speech occurs when the neural pathway between the brain and speech muscles becomes disrupted or lost. Someone with apraxia knows exactly what they want to say and can even write it down, but their brain can’t send the correct messages to make their speech muscles produce the intended sounds. The speech muscles themselves work fine, the disconnect happens at the neurological level.
AOS presents with varying levels of severity. Mild cases might involve occasional mispronunciations and irregularities in tone, rhythm, or emphasis (prosody). Severe cases can make speech nearly incoherent, with symptoms including inability to articulate words, groping for correct sound positions, off-target movements that distort sounds, and inconsistent pronunciation of the same words.
There are two main types. Acquired AOS results from brain damage in adults, often from stroke or traumatic brain injury. Childhood AOS appears in children born with the condition, though researchers haven’t been able to detect specific brain damage or structural differences. This makes childhood AOS somewhat mysterious, though research suggests a possible genetic component when close family members have learning or communication disorders.
Many SLPs specialize in treating apraxia. Research suggests that intensive speech therapy focusing on motor planning and sequencing may help improve communication abilities, particularly when intervention begins early in childhood. Treatment approaches typically emphasize repetitive practice of sound sequences and multisensory cueing techniques.
2. Stuttering (Stammering)
Stuttering is so recognizable that nearly everyone can identify it. Most people have experienced brief moments of stuttering at least once in their lives. The National Institute on Deafness and Other Communication Disorders estimates that three million Americans stutter, with up to 10% of children going through a stuttering phase. The good news is that three-quarters of children who stutter will outgrow it naturally.
What many people don’t realize is that stuttering can include non-verbal components. Beyond repetitions, prolongations, and blocks in speech, stuttering may involve involuntary or semi-voluntary physical actions, such as eye blinking, jaw tensing, or abdominal tightening (tics). Speech-language pathologists are trained to identify all symptoms of stuttering, including these subtle non-verbal indicators, which is why professional evaluation matters.
This fluency disorder typically emerges when children are learning to talk, usually between the ages of 2 and 5. It rarely develops for the first time in adulthood, though many adults carry a history of stuttering from childhood. Stuttering becomes a concern when it impacts daily activities, causes anxiety in speaking situations, or leads someone to avoid certain activities, such as phone calls or presentations.
The causes of stuttering remain largely unknown. Research indicates a genetic component, as stuttering tends to run in families. Some theories suggest stuttering may be a form of involuntary tic. Most current research agrees that multiple factors likely contribute to the development of stuttering.
Because causes aren’t fully understood, treatment approaches focus primarily on behavioral strategies. Many people who stutter can identify triggers that precede stuttering episodes. SLPs can help clients recognize these triggers and develop coping strategies. Speech therapy may include techniques like controlled breathing, slowed speech rate, and desensitization to anxiety-producing speaking situations.
3. Dysarthria
Dysarthria is a symptom of nerve or muscle damage affecting the physical process of speaking. It manifests as slurred speech, slowed speech rate, limited tongue, jaw, or lip movement, abnormal rhythm and pitch, changes in voice quality, difficulty with articulation, labored speech, and related symptoms.
The condition results from damage to the muscles involved in speech (the diaphragm, lips, tongue, throat, and vocal cords) or to the nerves that control them. This means dysarthria can be caused by a wide range of conditions affecting people of all ages. In infants and young children, dysarthria may result from conditions like muscular dystrophy or cerebral palsy. In adults, common causes include stroke, tumors, multiple sclerosis, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS).
As an SLP, you can’t repair muscle or nerve damage directly. Treatment focuses on managing dysarthria symptoms through compensatory strategies and adaptive techniques. This may include helping clients slow their speech rate, implementing breath-support training, exercising speech muscles to maintain function, and teaching communication strategies to maximize intelligibility. Some clients benefit from augmentative and alternative communication (AAC) devices when speech becomes too difficult.
4. Lisping
Lisping is easily recognized by the general public, but speech-language pathologists bring an extra level of expertise when treating patients with lisping disorders. SLPs can distinguish between a lisp and other disorders that might present similarly, such as apraxia, aphasia, impaired expressive language development, or speech impediments caused by hearing loss.
SLPs also distinguish between five different types of lisps. The most common is the interdental or dentalized lisp, where someone produces a “th” sound when attempting the “s” sound. This happens when the tongue reaches past or touches the front teeth during speech. Other types include lateral lisps (air escapes over the sides of the tongue), palatal lisps (tongue contacts the soft palate), and strident lisps (high-pitched, harsh-sounding).
Lisps are functional speech disorders, meaning they result from learned motor patterns rather than structural abnormalities. This means SLPs can often help clients make significant improvements or completely eliminate lisps through targeted therapy. Treatment typically proves most effective when implemented early, though adults can also benefit from intervention.
Speech therapy for lisping typically includes pronunciation and articulation coaching, teaching the proper tongue placement for specific sounds, practice with mirror feedback, and exercises to strengthen speech muscles. Simple activities like drinking through straws can help develop the precise muscle control needed for correct sound production.
Experts recommend professional SLP intervention if a child reaches age four and still has an interdental or dentalized lisp. For other lisp types, earlier evaluation and intervention is recommended.
5. Spasmodic Dysphonia
Spasmodic dysphonia (SD) is a chronic, long-term disorder affecting voice production. It’s characterized by involuntary spasms of the vocal cords during speech, resulting in a voice that may sound shaky, hoarse, groaning, tight, strained, or jittery. The spasms can cause significant variability in vocal emphasis and pitch. Many SLPs develop expertise in the treatment of spasmodic dysphonia.
SLPs most often encounter this disorder in adults, with first symptoms typically appearing between ages 30 and 50. SD can result from various factors related to aging, including nervous system changes, muscle tone disorders, and laryngeal dystonia. Some cases have no identifiable cause.
Diagnosing SD requires a team approach. Because vocal cord spasms can be difficult to isolate as the source of voice irregularities, SLPs typically work alongside ear, nose, and throat doctors (otolaryngologists) and neurologists to reach an accurate diagnosis.
After diagnosis, SLPs can help optimize voice production through therapeutic techniques. Speech therapy may be particularly helpful in mild SD cases. Treatment often emphasizes breathing control techniques to maintain steady airflow from the lungs, vocal exercises, and strategies to reduce vocal strain. Some clients also benefit from medical interventions like Botox injections or, in severe cases, surgical options.
6. Cluttering
Cluttering is sometimes self-diagnosed by people who talk rapidly when nervous, but an accurate diagnosis requires professional evaluation. This is why SLPs play a crucial role in making proper cluttering diagnoses and distinguishing cluttering from normal fast-paced speech patterns.
A fluency disorder, cluttering is characterized by speech that’s too rapid, too irregular, or both. To qualify as cluttering, the speech must also include excessive use of filler words (“well,” “um,” “like,” “hmm,” “so”), excessive exclusion or collapsing of syllables, or abnormal syllable stresses and rhythms. The overall effect is that speech becomes difficult for listeners to understand.
First symptoms typically appear in childhood. Like other fluency disorders, speech therapy may help improve or manage cluttering symptoms. Intervention tends to be most effective early in life, though adults can also benefit from working with an SLP.
Treatment methods for cluttering include delayed auditory feedback (hearing their own speech on a slight delay), syllable articulation and enunciation coaching, games involving rapid word retrieval, practice with proper pausing and phrasing in sentences, and increasing self-awareness through video recording. Many clients don’t realize how cluttered their speech sounds until they hear or see themselves on a recording.
7. Selective Mutism
Selective mutism (formerly called elective mutism) occurs when someone doesn’t speak in certain situations despite being physically able to speak. It most commonly affects children and often presents as a child who speaks comfortably at home but remains silent at school or in other social settings.
This condition relates to psychological factors rather than physical speech difficulties. Selective mutism typically appears in children who are extremely shy, have anxiety disorders, or are experiencing social withdrawal or isolation. These underlying psychological factors have their own origins and should be addressed through counseling or other psychological interventions.
Diagnosing selective mutism involves a team of professionals, including SLPs, pediatricians, psychologists, and psychiatrists. SLPs play an important role in this diagnostic process because certain speech-language disorders can produce effects similar to those of selective mutism, including stuttering, aphasia, apraxia of speech, or dysarthria. It’s essential to rule out these physical speech disorders before confirming a selective mutism diagnosis.
Even though selective mutism has psychological roots, SLPs can still provide valuable support. Speech-language pathologists can work with selectively mute children to create tailored behavioral treatment programs and address any co-occurring speech and language issues, such as stuttering, that may contribute to psychological factors like excessive shyness or social anxiety.
8. Aphasia
According to the National Aphasia Association, approximately one million Americans have some form of aphasia. This communication disorder results from damage to the brain’s language centers. Unlike apraxia of speech and dysarthria, which affect the physical production of speech, aphasia specifically impairs the brain’s ability to process and produce language.
Anyone can develop aphasia because brain damage can occur from numerous causes. However, SLPs most commonly encounter aphasia in adults, particularly stroke survivors. Other causes include brain tumors, traumatic brain injuries, infections affecting the brain, and degenerative brain diseases like Alzheimer’s or primary progressive aphasia.
Aphasia can affect different aspects of communication, including speaking, understanding spoken language, reading, and writing. Some people with aphasia struggle to find the right words (anomia), while others can speak fluently but their words don’t make sense (fluent aphasia). Some understand language well but can’t produce speech (expressive aphasia), while others speak but can’t understand what’s said to them (receptive aphasia).
Speech-language pathologists have an important role in diagnosing aphasia, working alongside neurologists. As an SLP, you’ll assess factors like reading and writing abilities, functional communication skills, auditory comprehension, and verbal expression to determine the type and severity of aphasia.
Because brain damage repair remains limited, your role as an SLP focuses on helping clients develop coping strategies and alternative communication methods. The brain demonstrates remarkable plasticity, sometimes recruiting undamaged areas to compensate for lost function. Speech therapy may help stimulate this neuroplasticity through targeted activities designed to improve affected language skills. Individual responses to therapy vary significantly based on factors like the extent and location of brain damage, time since injury, and overall health.
9. Speech Delay
A speech delay is when a child does not make typical attempts at verbal communication for their age. The term “alalia” was used historically but is now considered outdated in modern clinical practice. Because numerous factors can cause speech delays, speech-language pathologists play a critical role in evaluation and diagnosis.
Many potential reasons exist for a child not using age-appropriate communication. These range from the child simply being a “late bloomer” who takes longer than average to develop speech, to serious conditions like hearing loss, neurological disorders, autism spectrum disorder, or brain injury. An SLP’s role is to systematically evaluate each possibility until an explanation is found.
Evaluating a child with speech delay starts by distinguishing between two main categories: speech and language. Speech involves the physical organs of speech (tongue, mouth, vocal cords) and the muscles and nerves that connect them to the brain. Disorders like apraxia of speech and dysarthria fall into this category, as do physical conditions like cleft palate or hearing loss.
The language category primarily relates to the brain and can be affected by brain differences or developmental disorders such as autism. Many types of brain conditions manifest differently, and developmental disorders present with unique patterns. The SLP conducts comprehensive evaluations to identify specific factors contributing to the speech delay.
Once the cause or causes are identified, the SLP can develop appropriate treatment and monitoring plans. For many speech-language disorders that cause speech delays, research suggests that early intervention and evaluation by an SLP can significantly improve outcomes. The earlier treatment begins, the better the potential for improvement in many cases.
10. Communication Issues Related to Autism Spectrum Disorder
While autism spectrum disorder itself isn’t a speech disorder, it makes this list because communication challenges and autism frequently occur together. According to 2023 CDC estimates, approximately one in 36 children in the United States has an autism spectrum disorder. By definition, all individuals with autism experience social communication differences or challenges.
Speech-language pathologists often serve as critical members of multidisciplinary teams making autism spectrum diagnoses. These teams typically also include pediatricians, occupational therapists, neurologists, developmental specialists, and physical therapists. The American Speech-Language Hearing Association reports that communication problems are often among the first detectable signs of autism, which is why language disorders represent one of the primary diagnostic criteria.
Communication challenges you’re likely to encounter in individuals on the autism spectrum include apraxia of speech (research from Penn State found that 64% of children diagnosed with autism also showed signs of childhood apraxia of speech), echolalia (involuntary repetition of others’ vocalizations), unusual inflection and tone (prosody), delayed language development, difficulty with pragmatic language (social use of language), and challenges with non-verbal communication like gestures and facial expressions.
Speech therapy for individuals with autism focuses on improving functional communication skills, which might include verbal speech, sign language, picture communication systems, or speech-generating devices, depending on individual needs and abilities. Treatment plans are highly individualized because autism presents differently in each person.
Understanding Speech vs. Language Disorders
One of the first distinctions you’ll learn in your SLP graduate program is the difference between speech disorders and language disorders. While often used interchangeably by the general public, these terms describe different types of communication challenges.
Speech disorders involve the physical production of sounds. These disorders affect how someone uses their mouth, tongue, lips, vocal cords, and breath to create sounds. Speech disorders include articulation disorders (difficulty producing specific sounds), phonological disorders (patterns of sound errors), voice disorders (problems with pitch, volume, or quality), and fluency disorders (stuttering, cluttering).
Language disorders involve the comprehension and use of language itself, whether spoken, written, or gestural. These disorders affect how someone understands what others say (receptive language) or how they express their own thoughts (expressive language). Language disorders can include difficulty with vocabulary, grammar, forming sentences, understanding questions, following directions, or using language appropriately in social situations.
It’s important to understand that someone can have a speech disorder without a language disorder. For example, a child with a lisp may have perfect language comprehension and expression but struggle to produce certain sounds. Conversely, someone can have a language disorder without speech difficulties, like an individual with autism who speaks clearly but struggles with pragmatic language use.
Many individuals have both speech and language disorders simultaneously. A child with autism might have both difficulty with the physical production of speech (childhood apraxia) and challenges with language comprehension and social communication. This is why a comprehensive evaluation by an SLP is so important.
As an SLP, you’ll conduct thorough assessments to determine whether a client has a speech disorder, language disorder, or both. This distinction guides your treatment planning and helps you set appropriate therapy goals. Understanding this difference also helps you explain to clients and families exactly what challenges they’re facing and what progress might look like.
When to Seek Professional Evaluation
Knowing when to seek evaluation from a speech-language pathologist can be challenging for parents and adults concerned about communication abilities. While every individual develops at their own pace, certain red flags warrant professional assessment.
Developmental Milestones and Red Flags by Age
Infants and Toddlers (0-3 years):
Consider evaluation if a child:
- Isn’t cooing or making sounds by 6 months
- Isn’t babbling by 12 months
- Doesn’t respond to their name by 12 months
- Isn’t saying single words by 16 months
- Doesn’t combine two words by 24 months
- Has lost previously acquired speech or language skills at any age
- Has difficulty feeding, chewing, or swallowing
Preschool Age (3-5 years):
Seek assessment if a child:
- Is difficult for family members to understand after age 3
- Is difficult for strangers to understand after age 4
- Isn’t using 3-4 word sentences by age 3
- Doesn’t ask questions or tell stories by age 4
- Shows frustration with the inability to communicate
- Has an interdental lisp after age 4
- Stutters for more than 6 months or if stuttering causes distress
School Age (6+ years):
Consider evaluation if a child:
- Has difficulty following multi-step directions
- Struggles to organize thoughts when speaking or writing
- Has difficulty with reading comprehension
- Avoids speaking situations due to speech difficulties
- Shows sudden changes in speech or language abilities
Adults:
Seek evaluation if you experience:
- Sudden difficulty speaking, understanding, reading, or writing (possible stroke)
- Gradual decline in communication abilities
- Voice changes lasting more than two weeks
- Difficulty swallowing
- Chronic hoarseness
- Communication difficulties following injury or illness
How to Find a Certified Speech-Language Pathologist
When seeking evaluation, look for an SLP who holds the Certificate of Clinical Competence in Speech-Language Pathology (CCC-SLP) from the American Speech-Language-Hearing Association (ASHA). You can find certified SLPs through the ASHA ProFind directory, which allows you to search by location and specialty area.
Most speech therapy services are covered by health insurance, Medicare, and Medicaid when deemed medically necessary. Many school districts also provide speech-language services to students who qualify under special education law.
What to Expect During an Evaluation
A comprehensive SLP evaluation typically includes a case history review, hearing screening, observation of communication in natural contexts, standardized assessment tools, analysis of speech and language samples, and discussion of concerns with the client or family. The SLP will then provide a diagnosis (if appropriate), explain findings, discuss treatment recommendations, and answer questions.
Remember that seeking evaluation early doesn’t mean overreacting. Research consistently shows that early intervention produces better outcomes for most communication disorders. If you’re concerned, it’s better to have a professional assessment that reveals no issues than to wait and potentially miss the optimal window for intervention.

Frequently Asked Questions
How do speech-language pathologists diagnose communication disorders?
SLPs use comprehensive evaluation methods, including case history review, standardized assessment tools, observation of communication in natural settings, hearing screenings, and analysis of speech and language samples. The diagnostic process may involve collaboration with other professionals, such as audiologists, neurologists, or psychologists. Diagnosis considers not only what the person does but also how communication difficulties impact daily life and development.
How long does speech therapy typically take?
The duration of speech therapy varies widely depending on the type and severity of the disorder, the individual’s age, how consistently they attend therapy, and how consistently they practice at home. Some conditions, like mild articulation disorders, may improve in a few months, while others, like aphasia following severe stroke, may require years of therapy. Your SLP will provide realistic timeframes based on your specific situation and will regularly reassess progress and adjust treatment plans.
Can adults benefit from speech therapy, or is it mainly for children?
Adults absolutely can benefit from speech therapy. While many communication disorders begin in childhood, adults may develop disorders from stroke, brain injury, progressive neurological conditions, or voice problems from vocal strain. Adults also seek therapy for childhood conditions they never addressed, like stuttering or articulation disorders. Research shows that neuroplasticity allows the adult brain to form new connections and learn compensatory strategies at any age, making therapy valuable throughout the lifespan.
Are speech disorders genetic?
Some speech and language disorders have a genetic component, though most conditions likely result from complex interactions between genetic and environmental factors. Research indicates that stuttering, childhood apraxia of speech, and certain language disorders tend to run in families. However, having a family history doesn’t guarantee a child will develop the same disorder, and many people with speech disorders have no family history. Genetic factors represent just one piece of a larger puzzle.
Will my insurance cover speech therapy?
Most health insurance plans, including Medicare and Medicaid, cover speech therapy when deemed medically necessary. Coverage typically requires a physician referral and diagnosis of a covered condition. School-age children may receive speech services through their school district if they qualify under the Individuals with Disabilities Education Act (IDEA). Coverage amounts and requirements vary by plan, so check with your insurance provider about specific benefits, copays, and any visit limitations.
What’s the difference between a speech therapist and a speech-language pathologist?
These terms refer to the same profession. “Speech-language pathologist” (SLP) is the official professional title, while “speech therapist” is a more informal term commonly used by the public. All SLPs must hold at least a master’s degree, complete supervised clinical practice, pass a national examination, and maintain certification. The field has used the SLP title since the 1970s to better reflect the broad scope of practice that includes both speech and language disorders.
Can speech disorders be prevented?
Some speech disorders can be prevented, while others cannot. Acquired disorders from stroke may be reduced through managing risk factors like high blood pressure and diabetes. Voice disorders from vocal strain can be prevented through proper vocal hygiene. Hearing-related speech issues can be addressed through early hearing screening and intervention. However, many disorders have unknown causes or genetic factors that can’t be prevented. The focus should be on early identification and intervention, which research suggests can significantly improve outcomes even when prevention isn’t possible.
