TL;DR
Apraxia of speech isn't cured overnight, but it responds well to specific, frequent therapy. The three treatments with the best evidence are DTTC, NDP3, and ReST. Kids need 3 to 5 sessions a week during intensive phases. Daily home practice by parents is the single biggest factor in how fast a child moves forward.
What is apraxia of speech and why is it different from other speech delays?
Apraxia of speech is a motor planning disorder. The brain knows what word it wants to say, but it struggles to send the right sequence of movement instructions to the lips, tongue, and jaw. That's different from a phonological disorder, where a child hasn't learned the sound rules of language, or a muscle weakness problem like dysarthria, where the muscles themselves don't work well.
The American Speech-Language-Hearing Association (ASHA) defines childhood apraxia of speech (CAS) as "a neurological childhood speech sound disorder in which the precision and consistency of movements underlying speech are impaired in the absence of neuromuscular deficits." [1] That last phrase matters: the muscles are fine. The problem is in the motor program.
This distinction changes everything about treatment. Exercises that strengthen the tongue or lips, like blowing horns or chewing resistive foods, don't help CAS. What helps is practicing actual speech movements, repeatedly, with the right kind of feedback. If your child has been doing a lot of non-speech oral motor exercises and isn't making progress, that's worth raising with their speech-language pathologist (SLP).
You can read a fuller breakdown of what the diagnosis means on our apraxia of speech page, and a deeper look specifically at the childhood version at childhood apraxia of speech.
Can apraxia of speech be fixed?
"Fixed" is the wrong frame, but progress is real and often big. Most children with childhood apraxia of speech (CAS) become functional communicators, and many reach age-appropriate speech. How far they get depends on severity, how early treatment starts, and how consistently they practice.
Mild CAS caught before age 3 and treated intensively? Many of those kids are indistinguishable from peers by kindergarten. Moderate to severe CAS diagnosed later, or treated inconsistently? Progress is slower, and some residual differences may stay into adulthood. That's not a reason to give up. It's a reason to start now and be strategic.
Adults with acquired apraxia of speech (often after stroke or brain injury) respond to treatment too. The same motor-learning principles apply, though the brain's plasticity is different from a young child's. Early intervention before age 5 is linked to better outcomes, though meaningful gains are possible at any age. [2] Our early intervention guide covers why the youngest years matter most.
Nobody has clean population-level data on what percentage of children fully "resolve" CAS, partly because severity varies so much and partly because the diagnosis itself was standardized relatively recently. The closest systematic review, published in the Journal of Speech, Language, and Hearing Research in 2014, found strong evidence that treatment works, even if long-term outcome data by severity are still thin. [3]
Which treatments have the best evidence for apraxia?
Three approaches have the strongest research base for CAS specifically. They all differ from general articulation therapy, so it matters that your SLP knows which one they're using and why.
Dynamic Temporal and Tactile Cueing (DTTC) is probably the most studied. Developed by Edythe Strand at Mayo Clinic, it starts with simultaneous production (the child and SLP say the word at exactly the same time) and gradually fades support as the child gets more accurate. It's slow, deliberate, and very repetitive. That's the point. [3]
Nuffield Dyspraxia Programme (NDP3) is a structured hierarchy that builds from sounds to syllables to words to sentences, with a lot of visual support. It's more common in the UK but available internationally.
Rapid Syllable Transition Treatment (ReST) was developed at the University of Sydney and targets multi-syllable words, which are often the hardest thing for kids with CAS. A 2018 randomized controlled trial found that children who received ReST made significantly greater gains than a no-treatment control group. [4]
Some SLPs also use the Kaufman Speech to Language Protocol (K-SLP), which breaks words down to their most motorically simple form and builds back up. It has good clinical support even if the formal research base is thinner than DTTC.
| Treatment | Best evidence for | Who developed it | Available research |
|---|---|---|---|
| DTTC | CAS, moderate-severe | Edythe Strand, Mayo Clinic | Multiple studies, systematic reviews |
| NDP3 | CAS, all ages | Nuffield Hearing & Speech Centre | Good clinical evidence, fewer RCTs |
| ReST | CAS, multi-syllable words | Uni. of Sydney team | RCT published 2018 |
| K-SLP | CAS, early words | Nancy Kaufman | Clinical evidence, limited RCTs |
| Non-speech oral motor exercises | Not recommended for CAS | Various | Evidence does not support use for CAS |
That last row is there for a reason. If an SLP's plan is mostly tongue exercises and blowing through straws, that's a red flag for a CAS diagnosis. ASHA's technical report explicitly states that non-speech oral motor exercises are not recommended as a primary treatment for CAS. [1]
How many sessions per week does a child with apraxia need?
More than most insurance companies want to cover. That's the honest answer.
Motor learning research is pretty clear that skills built through distributed, frequent practice are retained better than skills drilled in one long weekly session. For CAS specifically, ASHA's practice portal recommends frequent, intensive treatment, typically 3 to 5 sessions per week during active treatment phases. [1] Once a child starts hitting targets consistently, frequency can taper.
In practice, many families get one or two sessions a week through school or insurance. That can still produce progress, but it will be slower, and it puts more weight on what parents do at home between sessions. A child who gets two 45-minute sessions per week but practices targets for 10 minutes every day at home will almost always outperform a child who only does therapy once a week.
If your child is on an IEP, you can request a higher service frequency. Schools are required under IDEA to provide services that give the child educational benefit, and for a child with CAS, infrequent pull-out sessions may not meet that standard. [12] Getting a private SLP evaluation alongside the school evaluation gives you data to push back with.
Some families pursue intensive therapy camps, which compress many sessions into a few weeks. The Apraxia Kids organization lists summer intensive programs, and the research on massed practice (many sessions in a short period) for motor learning is genuinely promising, though not CAS-specific. [5]
What can parents do at home to help fix apraxia?
Home practice is not optional. It's where the motor learning actually consolidates. Your SLP should give you specific targets (exact words or syllable shapes your child is working on) and show you how to cue correctly at home.
Here's what good home practice looks like in real life. You pick 5 to 10 target words your SLP has cleared. You practice them in short sessions (5 to 15 minutes, depending on the child's age and stamina) every single day. You give the child time to try before jumping in with a correction. You use the same cuing hierarchy your SLP uses: if they're doing DTTC, you say the word together first, then see if the child can do it alone. You celebrate attempts more than perfect productions.
A few things to avoid. Don't lean on "Can you say ___?" as your main strategy. That's an open question, and kids with CAS often respond by going silent or saying something unrelated. Model the target instead, and give a clear opportunity to imitate. Don't correct every error on every word in conversation. Save the explicit practice for practice time, and keep conversation low-pressure.
For kids who are minimally verbal or who have very limited sound inventories, AAC devices can take enormous pressure off while speech motor skills develop. AAC does not slow speech development. There's no credible evidence it does, and some evidence it supports speech. [6]
If you want structured daily support between therapy sessions, tools like Little Words are built specifically for neurodivergent kids and can keep home practice consistent without making it feel like homework. Take the quiz at littlewords.ai/start to see if it fits your child's profile.
How long does it take to see improvement with apraxia treatment?
This one is genuinely hard to answer without knowing the child. Here are some real anchors.
With intensive treatment (4 to 5 sessions per week plus daily home practice), many families report noticing changes in specific target words within 4 to 6 weeks. That doesn't mean the child's overall intelligibility has jumped. It means the words being drilled are getting clearer. Generalization to untrained words and to spontaneous speech takes longer, often several months.
A child with mild CAS and no co-occurring conditions, starting treatment before age 4, might reach typical intelligibility within 1 to 2 years of consistent therapy. A child with severe CAS and co-occurring language or attention challenges might need 4 to 6 years of therapy and still use some compensatory strategies as an adult. Both of those are real outcomes, not failure cases.
CAS also has a pattern where progress seems to stall, then jumps. This is frustrating for families but consistent with how motor learning works. The brain is consolidating before it generalizes. If a child is stalling, the SLP should reassess which targets they're working on and whether the therapy approach needs to shift.
For kids who are also autistic or have co-occurring conditions, the timeline often runs longer, partly because coordinating attention during practice is itself a skill. Autism spectrum speech therapy approaches these overlapping challenges differently than CAS-only treatment.
How do you find an SLP who actually knows how to treat apraxia?
This is one of the most useful practical questions parents ask, and it has a real answer.
The Apraxia Kids organization (apraxia-kids.org) keeps a directory of SLPs who have self-identified as having training in CAS. That's not a perfect filter, but it's a start. ASHA's Find a Professional directory lets you search by specialty area. [5]
When you interview an SLP, ask three specific questions. First: what treatment approach do you use for CAS? If they mention DTTC, ReST, NDP3, or Kaufman, that's a good sign. If they talk mostly about oral motor exercises or just say "articulation therapy," that's a concern. Second: how many children with confirmed CAS have you treated in the last two years? Experience matters in motor learning treatments. Third: what will home practice look like, and how will you tell me what to do between sessions?
You don't need to be a clinician to judge the answers. You just need to know what to listen for.
Online speech therapy is a legitimate option, and some of the most CAS-specialized SLPs work remotely. Telepractice for CAS has been studied: a 2019 study in the International Journal of Telerehabilitation found outcomes comparable to in-person treatment for school-age children. [7] That matters most if you live where CAS specialists are rare.
For background on what to expect from the therapy process generally, the speech therapy guide covers the basics.
Does apraxia treatment work for adults?
Yes, with some differences in approach and expectation.
Acquired apraxia of speech in adults (most often after stroke, traumatic brain injury, or neurodegenerative disease) responds to the same motor learning principles as CAS. DTTC has been adapted for adults. There's also good evidence for Treatment of Underlying Forms (TUF) and for metrical stress treatments when a person has trouble with word and sentence rhythm.
Adult brains have less neural plasticity than young children's, which generally means progress is slower and takes more effort. But "slower" doesn't mean negligible. Many adults who commit to intensive, consistent therapy regain functional communication.
The American Academy of Neurology and ASHA both note that intensity matters as much for adults as for children: more frequent sessions in the early post-stroke period are linked to better outcomes. [8] The critical window is real but often overstated. Meaningful gains are still possible years after onset.
For adults, self-monitoring is a key part of therapy that's less central with young children. Adults can learn to notice when a word went wrong and use deliberate self-correction strategies. The speech therapy for adults page has more on adult-specific approaches.
What should you do if your child was just diagnosed with apraxia?
Take a breath. Then move quickly on the practical steps, because early and frequent treatment makes a real difference.
First, get the full evaluation report from the SLP or team who diagnosed your child. You want to understand the severity rating (mild, moderate, severe) and whether there are co-occurring diagnoses like autism, language delay, or phonological disorder. Each of these changes the treatment plan.
Second, if the diagnosis came through your school district, you can pursue a private SLP who specializes in CAS at the same time. School services and private therapy are not mutually exclusive, and school SLPs are often generalists who may not have deep CAS training.
Third, connect with other families. The Apraxia Kids organization has a parent community, state chapters, and an annual conference. What families share about what actually worked is often more granular than anything in a pamphlet. [5]
Fourth, learn the basics of whatever treatment approach your SLP is using. You don't need a master's degree, but understanding why your child is doing what they're doing makes home practice more effective and helps you advocate in IEP meetings.
A formal medical workup is sometimes warranted too. In a subset of children, CAS is associated with a genetic condition (FOXP2 variants, chromosome 16p11.2 deletions, and others). A developmental pediatrician or geneticist can determine whether that's relevant for your child. The American Academy of Pediatrics recommends referring any child with suspected CAS to a neurologist or developmental pediatrician if the cause is unclear. [9]
Is apraxia of speech related to autism?
It can be, and this overlap gets missed too often.
CAS is more common in autistic children than in the general population, though exact prevalence numbers vary widely depending on how both diagnoses are made. Some research suggests that up to 65% of minimally verbal autistic children may have features consistent with CAS, though that number comes from studies with specific sampling and should be read cautiously. [10]
The tricky part is that autism and CAS can look similar on the surface: inconsistent sound production, difficulty with imitation, limited spontaneous speech. Telling them apart takes an SLP who knows both well. When both are present, treatment needs to address the motor planning component (CAS) and the social communication and sensory components (autism).
For autistic children who are minimally verbal or nonverbal, AAC is often the right first move, even while speech therapy continues. The research strongly supports using AAC alongside speech treatment rather than waiting until speech develops. [6] Our echolalia and echolalia meaning articles cover another pattern that's common in autistic children and sometimes confused with apraxia.
If your child has both diagnoses, look specifically for an SLP with experience in both areas. The autism spectrum speech therapy page goes into more detail on what a combined approach looks like.
How do you know if the apraxia treatment is working?
Your SLP should be tracking data every session. If they're not showing you measurable progress over time, ask why.
Good CAS therapy produces two measurable changes: accuracy on trained targets (the specific words being drilled) and generalization to untrained targets (new words with similar sound patterns). Both matter. A child who can produce trained words perfectly but doesn't generalize at all may need a different treatment approach or different targets.
Parents can track progress informally by keeping a short video every 4 to 6 weeks. Film your child saying the same 10 words (a mix of trained targets and everyday words). Compare across time. You'll often see progress that's hard to notice day to day.
Overall intelligibility, meaning the percentage of speech a stranger can understand, is the broadest outcome measure. There are standardized assessments for this, like the Intelligibility in Context Scale (ICS), which is free and parent-reported. [11] A child going from 20% intelligible to 60% intelligible over a year of treatment is making real, meaningful progress even if it doesn't feel like "fixed."
Six months in with no measurable change in trained targets? That's a signal to reassess. Either the targets need to change, the approach needs to change, or the frequency needs to increase. A good SLP welcomes that conversation. If yours doesn't, that's information too.
Tools like Little Words give parents a structured way to track which words their child is attempting and succeeding with at home, which gives your SLP better data to work from between formal assessments.
Frequently asked questions
Can apraxia of speech go away on its own without therapy?
There's no good evidence that CAS resolves without treatment. It is not a developmental delay that children simply outgrow. A few children with very mild presentations may make progress with general language exposure, but the research consistently shows that explicit motor-based therapy is what produces reliable improvement. Waiting is not a neutral choice. It costs time during the most neuroplastic period of development.
What's the difference between apraxia and a speech delay?
A speech delay means a child is producing sounds and words later than typical, but the pattern of development is mostly normal. Apraxia is a motor planning disorder where speech is inconsistent, harder on longer or more complex words, and doesn't improve the way a typical delay does with general exposure. A child with a delay usually responds well to standard articulation therapy. A child with CAS needs motor-based approaches like DTTC or ReST.
At what age can apraxia be diagnosed?
Most specialists are cautious about diagnosing CAS before age 3 because there isn't enough speech to evaluate the pattern reliably. Some experienced SLPs will use the term 'suspected CAS' for younger children and begin appropriate treatment anyway, since the approach is low-risk and potentially high-benefit. Apraxia Kids recommends seeking evaluation if a child shows red flags (very limited sounds, highly inconsistent speech, difficulty imitating) even before a formal diagnosis is possible.
Does apraxia affect reading or learning?
CAS can co-occur with dyslexia and other language-based learning differences, and some children with CAS have a harder time with phonological awareness tasks that underlie reading. This isn't universal. Many children with CAS have strong language and literacy skills. But it's worth monitoring, and an SLP who also screens for phonological awareness can catch any issues early. A full speech-language evaluation (more than an articulation screen) is the right starting point.
Is apraxia of speech genetic?
Sometimes. Variants in the FOXP2 gene are the most studied genetic link to speech and language disorders including apraxia, though FOXP2 variants account for only a small share of CAS cases. Deletions at chromosome 16p11.2 and galactosemia are also associated with CAS. For most children, no specific genetic cause is found. If there's a family history of speech or language difficulties, or CAS occurs alongside other developmental concerns, a genetics referral is reasonable to consider.
Should a child with apraxia use AAC while they're working on speech?
Yes, in most cases. AAC (augmentative and alternative communication, including picture boards, speech-generating devices, or apps) does not slow speech development, and there's no credible evidence it does. For a child with limited verbal output, AAC reduces frustration, supports language development, and keeps communication going while motor skills are built. Many SLPs recommend starting AAC and speech therapy at the same time rather than waiting for speech to develop first.
What are the signs that a child has apraxia rather than just being a late talker?
Key signs include: speech that is highly inconsistent (the child says 'bye' clearly today but can't produce it tomorrow), errors that increase as words get longer, better performance on automatic words (like 'mama') than requested ones, limited vowel variety, and groping movements of the mouth while searching for a sound. Late talkers generally have fewer words but produce them consistently. If you're seeing the inconsistency and groping pattern, an SLP evaluation is the right next step.
How do I get school services for a child with apraxia?
Request a special education evaluation in writing from your school district. Under IDEA (the Individuals with Disabilities Education Act), the school must evaluate within 60 days and, if the child qualifies, develop an IEP. CAS typically qualifies under the category of Speech or Language Impairment. You can also request specific services (frequency, approach) in the IEP meeting. An independent private SLP evaluation gives you your own data to bring if you disagree with the school's recommendations.
Are there apps that help with apraxia of speech practice?
Several apps can support home practice, though none replace a qualified SLP. Apps are most useful for keeping daily practice consistent between sessions. Look for ones that let you load your child's specific targets (the words their SLP is working on) rather than generic word lists, give clear models for imitation, and track attempts over time. Any app should supplement therapy guided by an SLP who knows your child's motor learning profile, not replace it.
Does online speech therapy work for apraxia?
Yes. A 2019 study in the International Journal of Telerehabilitation found that school-age children receiving CAS treatment via telepractice made comparable gains to those getting in-person therapy. What needs to work: a stable video connection, good audio quality, and an SLP comfortable delivering motor-based cueing remotely. For families in areas without local CAS specialists, online therapy meaningfully expands access to experienced clinicians.
How much does apraxia speech therapy cost without insurance?
Private SLP sessions in the US typically run between $100 and $300 per session, with big regional variation. At the recommended 4 to 5 sessions per week during intensive phases, that's $400 to $1,500 per week out of pocket. Many SLPs offer sliding scale fees. University training clinics often provide services at much lower cost. Some states have Medicaid waivers that cover private therapy for children with developmental diagnoses. Eligibility and coverage vary by state.
Can a child with severe apraxia learn to speak?
Many do, though the path is longer and the endpoint less predictable than with mild CAS. Some children with severe CAS become functional verbal communicators after years of intensive therapy. Others reach partial verbal communication alongside steady AAC use. Severity at diagnosis does not perfectly predict long-term outcome. Early treatment, high frequency, consistent home practice, and an experienced SLP are the factors most within a family's control. Starting treatment is always better than waiting.
What is DTTC and how does it work?
Dynamic Temporal and Tactile Cueing (DTTC) is a motor-based treatment for CAS developed by Edythe Strand at Mayo Clinic. The SLP and child say a target word at the same time at first (maximum support), then the SLP fades their voice gradually until the child produces the word independently. The SLP also uses touch cues on the face or jaw to guide movement when needed. The goal is to build a reliable motor program through many repetitions with decreasing support.
