If your child has been diagnosed with — or you suspect — childhood apraxia of speech (CAS), you probably have a lot of questions. CAS is one of the most complex speech disorders in children, but with the right therapy approach, children with CAS can make remarkable progress.
What Is Childhood Apraxia of Speech?
Childhood apraxia of speech (CAS) is a motor speech disorder. It's not a problem with muscle weakness or understanding language. Instead, the brain has difficulty planning and coordinating the precise movements of the lips, tongue, jaw, and palate needed to produce clear speech.
Think of it like this: your child knows what they want to say, but the "motor plan" — the brain's instructions to the speech muscles — doesn't work smoothly. This results in inconsistent speech errors, difficulty with longer words, and choppy-sounding speech.
How Is CAS Different From Other Speech Disorders?
| Feature | CAS | Articulation Disorder | |---------|-----|-----------------------| | Error consistency | Inconsistent — the same word may be said differently each time | Consistent — the same sound error occurs predictably | | Difficulty increases with | Longer or more complex words | Specific sounds regardless of word length | | Imitation | Often harder to imitate sounds/words on demand | Can usually imitate sounds in isolation | | Prosody | May sound monotone or have unusual rhythm | Typically normal rhythm and intonation |
Signs of CAS
Common signs parents notice include:
- Limited babbling as an infant
- Late first words (after 12–18 months)
- Saying a word correctly once, then being unable to repeat it
- Groping — visible struggle to move the mouth into position for sounds
- Making different errors on the same word
- Difficulty with longer phrases (may say "up" clearly but struggle with "pick me up")
- Unusual rhythm or stress in speech
How Is CAS Diagnosed?
CAS should be diagnosed by a speech-language pathologist (SLP) with expertise in motor speech disorders. Our childhood apraxia of speech program is designed specifically for children with this diagnosis. The evaluation typically includes:
- An oral motor exam to check the structure and movement of the speech muscles
- Speech sound assessment looking at consistency of errors, ability to sequence sounds, and prosody
- Dynamic assessment — observing how the child responds to different cues and prompts
- Ruling out other conditions like dysarthria (muscle weakness) or phonological disorders
Evidence-Based Treatment for CAS
CAS requires a motor-based therapy approach — traditional articulation therapy (drill-based practice of individual sounds) is not effective for CAS. The most evidence-based approaches include:
PROMPT Therapy
PROMPT therapy (Prompts for Restructuring Oral Muscular Phonetic Targets) uses tactile cues — the therapist places their hands on the child's face and jaw to physically guide the correct movements for speech. This helps the brain build accurate motor plans.
Dynamic Temporal and Tactile Cueing (DTTC)
DTTC is an integral stimulation approach that uses simultaneous production (speaking together with the child), then systematically reduces cues as the child gains independence. It emphasizes movement accuracy and builds automaticity.
Kaufman Speech to Language Protocol
This approach simplifies word targets to the child's current motor capacity, then systematically shapes those simplified words toward the full target. It gives children early success while building toward more complex speech.
What Parents Can Do
- Practice at home — frequent, short practice sessions (5–10 minutes) throughout the day are more effective than one long session
- Be patient — CAS therapy requires high-intensity, long-duration treatment; progress may feel slow but it accumulates
- Reduce pressure to perform — avoid asking your child to "say it again" or "say it the right way" in everyday conversation
- Celebrate effort — praise your child for trying, not just for accuracy
- Stay consistent with therapy — research shows that 3–5 sessions per week produces the best outcomes for CAS
The Outlook
With appropriate, intensive therapy from an SLP experienced in motor speech disorders, children with CAS can and do make significant progress. Many children with CAS go on to communicate effectively and succeed in school. Early identification and the right treatment approach are key.

"CAS is complex, but it's treatable. The most important things are getting the right diagnosis, the right type of therapy, and enough intensity. I've seen children with CAS make incredible gains." — Laura Friedman, MS, CCC-SLP, QOM
