10-Minute Speech Practice That Doesn't Require Sitting Still

Last updated 2026-07-09

What is apraxia of speech, exactly?

Apraxia of speech (AOS) is a neurological motor speech disorder. The muscles of the mouth, tongue, and jaw work fine. The lungs work fine. The problem is upstream, in the brain's ability to plan and sequence the precise movements that produce speech sounds. ^[1]

Think of it like a GPS that has the right destination stored but keeps giving garbled turn-by-turn directions. The destination (the word) is intact. The navigation system (motor planning) is broken.

People with AOS often know exactly what they want to say. They may say a word correctly once and then be unable to reproduce it. They make inconsistent errors on the same sound in different attempts. Longer, more complex words are harder than short ones. They may grope visibly, with the lips and tongue searching for the right position before a sound comes out.

Apraxia occurs in two main populations. Childhood apraxia of speech (CAS) appears in young children and has no known cause in most cases, though it's associated with certain genetic conditions and sometimes with autism. Acquired AOS hits adults after stroke, traumatic brain injury, or neurodegenerative disease. ^[2]

The American Speech-Language-Hearing Association (ASHA) describes AOS as distinct from dysarthria (weakness or paralysis of speech muscles) and from aphasia, though all three can co-occur after a stroke. ^[1]

What is aphasia, and how is it different from a speech disorder?

Aphasia is a language disorder, not a motor speech disorder. It happens when damage to the brain disrupts the processing of language itself, meaning the ability to find words, construct sentences, understand what others say, read, or write. ^[3]

The National Aphasia Association estimates that roughly 2 million Americans currently live with aphasia, and about 180,000 new cases are diagnosed each year, most caused by stroke. ^[4]

Here's the distinction worth pinning down. A person with aphasia may have completely normal mouth movement and articulation. Their tongue works. Their motor planning works. But the word just isn't there when they reach for it, or it comes out scrambled at the language level before any motor planning even begins.

Someone with aphasia might say "fork" when they mean "spoon," or produce nonsense syllables that sound fluent but carry no meaning (jargon aphasia), or speak in short telegraphic bursts with grammatical words stripped out. None of those errors are motor errors. They're language errors.

Aphasia almost always follows damage to the left hemisphere of the brain, particularly areas around the Sylvian fissure. The exact type depends on which region is damaged. ^[3]

How do the symptoms compare side by side?

The surface behavior can look nearly identical to an untrained eye, which is exactly why the comparison matters clinically. Both conditions make speech difficult. Both can reduce a person to single words or silence. But the underlying errors are different in character.

One useful clinical observation: ask someone to repeat the same word three times. A person with pure AOS will likely produce it differently each time, searching and sometimes getting closer, sometimes further away. A person with aphasia will tend to make the same substitution or omission repeatedly. Inconsistency is the hallmark of AOS. ^[1]

Writing is another quick check. Because AOS is purely a motor speech problem (not a written language problem), most people with AOS can write or type what they want to say better than they can say it aloud. In aphasia, writing is usually impaired as well, because the underlying language system is damaged. ^[3]

What is Broca's aphasia, and why does it get confused with apraxia?

Broca's aphasia is the type most commonly mixed up with apraxia of speech, and the confusion makes sense because the two share so much surface territory. ^[5]

Broca's aphasia follows damage to Broca's area, a region in the left frontal lobe (Brodmann areas 44 and 45). Speech is nonfluent, telegraphic, and effortful. Grammatical words ("the," "is," "and") disappear. Short content words survive. The person often understands what's said to them reasonably well.

So you get someone saying something like "...walk...dog...park" with great effort, knowing they're not expressing themselves fully. Sounds a lot like AOS, right?

The difference is in the error type. In Broca's aphasia, the errors are at the word selection and grammatical level. In AOS, errors are at the sound and motor sequencing level. In practice, many people who've had a left frontal stroke have both. Broca's area sits right next to the motor regions involved in speech planning, so a stroke big enough to cause Broca's aphasia often damages the neighboring motor speech circuitry too. ^[5]

Researchers have debated for decades whether Broca's aphasia and AOS are fully separable syndromes or overlapping points on a continuum. The honest answer: pure forms exist, but co-occurrence is the rule after stroke, not the exception. A 2016 paper in Aphasiology noted that clinically pure AOS without any aphasia is relatively rare in stroke populations. ^[6]

For parents reading this because a child has been diagnosed: childhood apraxia of speech is not Broca's aphasia. CAS is a developmental condition. Broca's aphasia is an acquired adult syndrome following brain damage. The surface behaviors can occasionally look similar, but the populations, causes, and treatment approaches are distinct.

What causes apraxia vs what causes aphasia?

Acquired AOS and most types of aphasia share common causes: stroke is the leading one, followed by traumatic brain injury, brain tumors, and neurodegenerative diseases like primary progressive aphasia (PPA). ^[3][2]

The difference is in brain location. AOS typically follows damage to the left premotor cortex and supplementary motor area, or the left insula. Aphasia follows damage to the left perisylvian language network, which includes Broca's area (front), Wernicke's area (back), and the connections between them.

Childhood apraxia of speech is a different story entirely. It's not caused by stroke or injury in most children. The cause is usually unknown. It's associated with certain genetic conditions (FOXP2 gene variants appear in some families with speech and language disorders, though research here is still developing ^[7]), and CAS occurs at higher rates in children with autism, intellectual disability, and other developmental conditions. There's no brain lesion to point to in most cases.

Aphasia does not have a developmental form in the same way. Acquired childhood aphasia can happen if a child has a stroke or brain injury, but it's uncommon. When a young child appears to have language access problems, the more likely diagnosis is a developmental language disorder (DLD), which is a separate category from either aphasia or apraxia.

Can someone have both apraxia and aphasia at the same time?

Yes. Co-occurrence is common enough that it's worth treating as the default assumption after a left-hemisphere stroke, not a surprising complication.

A large stroke in the left middle cerebral artery territory can damage both the premotor/insular regions (producing AOS) and the perisylvian language areas (producing aphasia) in a single event. In that case, the person struggles with motor planning and language access at once, making both assessment and treatment more complex.

Clinicians working with stroke survivors often have to work hard to tease apart which errors come from which source, because treatment approaches differ. Motor speech therapy for AOS drills precise movement sequences at slow rates with a lot of repetition and feedback. Language therapy for aphasia targets word finding, sentence construction, and communication strategies. Treat only one when both are present, and progress stalls.

For children, the situation is different. CAS can co-occur with language disorders, but those language disorders are developmental in nature, not aphasia. Some children with CAS are late talkers with a broader language delay. Others have language skills that are actually ahead of their speech production. That variability is one reason CAS is tricky to diagnose in very young children.

How are apraxia and aphasia diagnosed?

Both conditions require evaluation by a licensed speech-language pathologist (SLP). A neurologist or physiatrist may be involved in the broader diagnostic workup, especially after stroke, but the speech-language diagnosis itself comes from an SLP.

For AOS, there's no single standardized test that all clinicians use, which is an honest limitation of the field. The Apraxia Battery for Adults (ABA-2) and the Kaufman Speech Praxis Test for Children (KSPT) exist, but many experienced clinicians also rely on careful observation of connected speech, repeated single-word production, and tasks like reciting the days of the week. ^[1]

For childhood apraxia specifically, ASHA's 2007 technical report identified three core features that should be present: inconsistent errors on consonants and vowels in repeated productions, disrupted coarticulatory transitions between sounds, and inappropriate prosody. ^[2] None of those features are hard-edged pass/fail criteria, which is why diagnosing CAS in children under three is genuinely difficult and why the diagnosis sometimes only becomes clear with time and trial therapy.

For aphasia, the Western Aphasia Battery (WAB-R) and the Boston Diagnostic Aphasia Examination (BDAE) are widely used standardized tools. They assess fluency, auditory comprehension, repetition, and naming, which together map onto the major aphasia types.

Brain imaging (MRI, CT) can show where damage occurred and is standard practice after stroke, but imaging alone doesn't diagnose either condition. The behavioral speech and language evaluation is what confirms and characterizes the disorder. ^[3]

For families sorting through this for a child, early intervention services under IDEA Part C (for children birth to age 3) can provide SLP evaluation at no cost to the family. After age 3, services move to Part B of IDEA through the school district. ^[8]

What does treatment look like for each condition?

Treatment approaches are genuinely different, which is the practical reason the diagnostic distinction matters.

For apraxia of speech, the evidence favors intensive, motor-focused therapy with a high number of practice trials per session. Approaches with the strongest research support include Dynamic Temporal and Tactile Cueing (DTTC), the Nuffield Dyspraxia Programme (for children), and Rapid Syllable Transition Treatment (ReST). ^[9] All of these work on the motor level: slowing down, providing physical or visual cues about where to place the articulators, then gradually fading cues as accuracy improves. The word or sentence being practiced is often chosen not for communicative value but for the motor target it provides (e.g., practicing consonant clusters).

For aphasia, treatment targets language access and communication. Word retrieval therapy, constraint-induced language therapy (CILT), script training, and partner training all have evidence behind them. Augmentative and alternative communication (AAC) is often introduced early, particularly in severe aphasia, to give the person a way to communicate while speech is limited. ^[3]

AAC deserves a mention in both contexts. For children with severe CAS who can't produce enough reliable speech to communicate needs, AAC devices can be life-changing. The concern that AAC will prevent a child from developing speech is not supported by the research. Multiple studies have found that giving a child full AAC access does not reduce speech attempts and often supports them.

For children with CAS, the frequency question matters a lot. Research on treatment intensity suggests that more sessions per week produce better outcomes than the same number spread thinly over time. ASHA cites studies supporting three to five sessions per week for children with CAS compared to the once-a-week model many school-based programs offer. ^[9]

If you want day-to-day practice tools between therapy sessions, apps built for speech production practice (not generic "educational" apps) can add practice volume. The Little Words app is one option built specifically for neurodivergent kids, with structured repetition activities you can use between SLP visits. You can start a quiz to see if it fits your child's profile.

Adults with aphasia often benefit from long-term therapy. Gains are documented years post-stroke, well beyond the acute phase. The idea that recovery plateaus at six months is outdated. A 2016 Cochrane review found speech and language therapy significantly improves functional communication, reading, writing, and expressive language in people with aphasia after stroke. ^[10]

How do outcomes compare for apraxia vs aphasia?

Both conditions can improve significantly with therapy. Neither is a ceiling condition where the person simply reaches maximum function and stops.

For children with CAS, outcomes depend heavily on severity, early identification, and therapy intensity. Many children with mild to moderate CAS reach age-appropriate or near-age-appropriate speech with consistent treatment. Children with severe CAS may keep some speech differences into adulthood, but functional communication is achievable for nearly all of them.

For adults with acquired AOS, recovery depends on lesion size and location, time since onset, and therapy intensity. Some people recover close to normal speech. Others make meaningful gains while retaining some motor speech difficulty. Pure AOS (without co-occurring aphasia) tends to have a better prognosis than the mixed picture.

For aphasia, prognosis is highly variable. Severity at onset is the strongest predictor. Younger age, smaller lesion size, and preserved comprehension tend to go with better recovery. Most spontaneous recovery happens in the first three to six months after stroke, but therapeutic gains continue well beyond that window with continued treatment.

Honestly, nobody has great comparative outcome data that puts AOS and aphasia side by side in a controlled way. Co-occurrence makes clean separation hard, and outcome measurement varies widely across studies.

What should parents do if they suspect their child has apraxia?

Seek an SLP evaluation specifically. A general pediatric checkup is not going to catch CAS. Pediatricians are not trained to diagnose it, and while a good developmental pediatrician might flag speech concerns, the diagnostic evaluation needs to come from an SLP with experience in motor speech disorders.

If your child is under three, contact your state's early intervention program. Under IDEA Part C, an evaluation is free and must be completed within 45 days of referral. ^[8] The evaluator may or may not diagnose CAS at that age (it's genuinely hard to diagnose in children under three), but the evaluation will document delay and qualify the child for services if delay is present.

If your child is over three, contact your local school district's special education office to request a speech and language evaluation. That evaluation is also free under IDEA Part B.

Private SLP evaluation is faster in most areas and may involve a clinician with more specific CAS expertise. If you go this route, ask explicitly whether the clinician has training and experience with childhood apraxia of speech.

ASHA maintains a "Find a Professional" directory at asha.org that lets you filter by specialty area, which is a reasonable starting point. ^[1]

For resources specifically on childhood apraxia, the Apraxia Kids organization (apraxia-kids.org) maintains practitioner directories and parent education materials. They're a legitimate nonprofit, not a commercial directory.

A diagnosis, even an uncertain early one, opens the door to early intervention and speech therapy services. That's the most important step.

Is apraxia related to autism?

This question comes up constantly, and the relationship is real but nuanced.

CAS occurs at higher rates in autistic children than in the general population. Estimates vary widely because both conditions are underdiagnosed and because the overlap has only recently gotten serious research attention. Some researchers estimate that 60 to 65 percent of minimally speaking autistic children may have co-occurring CAS, though that figure comes from smaller clinical samples, not large population studies, so treat it as a rough signal rather than a firm number. ^[12]

The overlap creates a diagnostic tangle. Some behaviors that look like "autism speech" (echolalia, inconsistent word production, difficulty with volitional speech versus automatic speech) also fit CAS. Some children diagnosed primarily as autistic have unrecognized CAS that's contributing substantially to their communication difficulties.

Apraxia does not cause autism, and autism does not cause CAS. They co-occur. Why is not fully understood, though shared genetic factors affecting brain development are a plausible mechanism.

For families: if your autistic child has limited or inconsistent speech, ask the SLP specifically whether CAS is in the picture. Autism spectrum speech therapy that doesn't address underlying motor speech issues is going to be less effective for a child who has both. More detail on the childhood form is at our childhood apraxia of speech overview.

Aphasia, by contrast, is not associated with autism. It's an acquired adult disorder in the vast majority of cases.

What if you're supporting an adult after stroke, rather than a child?

The principles are similar but the context is completely different. An adult who had fluent, grammatically complex language before a stroke and now has none of it is experiencing loss in a way that a child with CAS, who never had those skills, is not. Grief, frustration, depression, and social isolation are enormous parts of the aphasia picture that rarely apply to young children with CAS.

Family communication partner training matters a lot for adults with aphasia. Research supports that when communication partners learn to slow down, use gesture, write key words, and give adequate processing time, the person with aphasia communicates more successfully. That's not a consolation prize. It's actual treatment with documented outcomes.

For adults with acquired AOS or aphasia, speech therapy for adults can be delivered in person or via telehealth. Online speech therapy has grown substantially since 2020, and ASHA's evidence map finds outcome equivalence with in-person therapy for most speech and language disorders, including aphasia. ^[1]

AAC remains an option for adults too, and it's massively underused. Adults with severe aphasia are often good candidates for full-featured AAC systems, and the same evidence that debunks the "AAC suppresses speech" myth in children applies to adults.

Medicare Part B covers outpatient speech-language pathology services as medically necessary when provided by a qualified SLP. After a stroke, most people qualify. Medicaid coverage varies by state. ^[11]

Frequently asked questions

Can apraxia of speech and aphasia occur together?

Yes, and it's common. A left-hemisphere stroke can damage both the motor speech planning regions (causing AOS) and the language areas (causing aphasia) in one event. Co-occurrence makes assessment harder because the error types overlap in practice. A skilled SLP separates them through specific testing tasks, and treatment needs to address both when both are present.

How do you tell apraxia of speech and aphasia apart just by listening?

The clearest signals: a person with AOS makes inconsistent errors on the same word across attempts, gropes visibly with the articulators, and can often write what they can't say. A person with aphasia tends to make consistent substitutions at the word level, may produce fluent-sounding jargon with no real content, and has writing impairment too. Neither rule is absolute, especially when both conditions co-occur.

What is the difference between apraxia and Broca's aphasia specifically?

Broca's aphasia produces telegraphic, nonfluent speech with missing grammatical words, caused by damage to Broca's area in the left frontal lobe. AOS produces effortful, inconsistent sound-level errors from disrupted motor planning. They look similar on the surface but differ in error type and treatment. Many stroke survivors have both simultaneously because Broca's area sits adjacent to motor speech regions.

Does childhood apraxia of speech affect a child's intelligence?

No. CAS is a motor speech disorder. It affects how the brain plans and sequences speech movements, not cognitive ability or language understanding. Many children with CAS have average or above-average intelligence and strong receptive language. The challenge is purely in getting words out, not in knowing things or understanding the world.

Can apraxia of speech go away on its own?

In children, spontaneous improvement does happen with development, but waiting without treatment is not recommended. The research on therapy intensity strongly favors early, frequent intervention. In adults after stroke, some spontaneous recovery occurs in the first months, but it's typically incomplete without targeted motor speech therapy. The pattern of inconsistent errors and groping behavior rarely resolves fully without practice-based treatment.

Is aphasia the same as being nonverbal?

Not exactly. Aphasia is specifically a language processing disorder following brain damage, usually in adults. Nonverbal or minimally verbal is a descriptor used for children (often autistic) who produce little or no spoken language for a range of developmental reasons. The causes, brain mechanisms, and treatment approaches are quite different. Some nonverbal children have CAS; aphasia is rarely the correct diagnosis for a young child.

What kind of speech therapist should I look for if CAS is suspected?

Look for a licensed SLP with specific experience in motor speech disorders or childhood apraxia of speech. Ask directly: have you diagnosed and treated CAS before? The Apraxia Kids organization (apraxia-kids.org) has a provider directory. ASHA's Find a Professional tool at asha.org lets you filter by specialty. General SLP training covers CAS but depth of experience varies considerably across practitioners.

Is there a test to diagnose apraxia of speech?

There is no single universally used test. The Apraxia Battery for Adults (ABA-2) and the Kaufman Speech Praxis Test for Children (KSPT) are established tools. Many clinicians also use systematic observation, repetition tasks, and connected speech samples. ASHA identifies three core diagnostic features for childhood AOS: inconsistent sound errors, disrupted between-sound transitions, and inappropriate prosody. Diagnosis requires clinical judgment, more than a test score.

How many times per week should a child with CAS receive speech therapy?

ASHA's guidance and the research behind it generally supports three to five sessions per week for children with CAS, at least during the intensive phase of treatment. That's much higher than the one session per week typical of many school-based programs. If school-based therapy is the only option, families can advocate for increased frequency or supplement with private therapy and structured home practice.

Can adults with aphasia recover language years after a stroke?

Yes. The belief that recovery stops at six months is outdated. A 2016 Cochrane review found that speech and language therapy produces significant improvements in functional communication, reading, writing, and expressive language even in chronic aphasia. Neuroplasticity continues for years post-stroke. The gains tend to be smaller than in the acute phase but are real and clinically meaningful, particularly with intensive therapy.

Does apraxia of speech affect reading and writing?

Usually not directly. AOS is a motor speech disorder, so the primary impact is on spoken output. Most people with AOS can write or type what they can't say, which is actually one of the diagnostic clues. If reading or writing is also impaired, that suggests a co-occurring language disorder or aphasia, not the AOS itself.

What causes aphasia in children?

Acquired aphasia in children most commonly follows stroke, traumatic brain injury, or brain tumors. It's uncommon. Children's brains have more plasticity than adults, so recovery tends to be better, but language difficulties can persist. Developmental language disorder (DLD) is a separate and much more common condition in children that is not aphasia; DLD has no identifiable neurological lesion.

Is echolalia related to apraxia or aphasia?

Echolalia, repeating words or phrases heard from others, is most commonly associated with autism and is a language and communication pattern, not a motor speech disorder. It's not a feature of AOS or aphasia, though people with severe aphasia sometimes produce perseverative repetitions. Echolalia has its own clinical significance as a communication stage; see our overview of echolalia meaning for more detail.

Does AAC help children with apraxia?

Yes, particularly for children with severe CAS who can't produce enough reliable speech to meet their communication needs. Research does not support the fear that AAC reduces speech development. Multiple studies find AAC supports rather than suppresses spoken language attempts. Options range from low-tech picture boards to high-tech speech-generating devices. The goal is to give the child a reliable voice while speech therapy continues.
