Speech Therapy
Childhood apraxia of speech (CAS)
Clinically reviewed by Hannah Chamberlain
CAS is a motor speech disorder where the brain struggles to plan the movements for speech. It needs frequent, specific speech therapy — and responds to it.

What CAS is
Childhood apraxia of speech (CAS) is a motor speech disorder. The child knows what they want to say, but the brain has difficulty planning and coordinating the precise muscle movements needed to produce speech.[] It's not a problem of muscle weakness or of not understanding language — it's a planning problem, and that distinction shapes everything about how it's treated.
CAS is frequently confused with other speech sound disorders, which is why careful differential diagnosis by a speech pathologist matters.
What it looks like
- Inconsistent errors — the same word said differently each time
- Groping or visibly searching for the right mouth position
- Difficulty smoothly sequencing sounds and syllables
- More breakdown on longer or more complex words
- Speech that's hard to understand, sometimes markedly so
- Sometimes a history of limited babbling as a baby
How speech therapy helps
CAS responds to therapy, but it has specific requirements: frequent, intensive, one-to-one practice focused on movement rather than individual sounds in isolation.[] Evidence-based approaches include the Nuffield Dyspraxia Programme (NDP3) and Rapid Syllable Transition Treatment (ReST) — the latter developed in Australia.[][] The common thread is lots of repetition of speech movements, carefully structured.
A typical plan includes:
- Careful diagnosis — distinguishing CAS from other speech sound disorders
- A movement-based approach — practising syllables and sequences, not isolated sounds
- High-frequency practice — CAS needs more repetitions than most conditions
- Parent coaching — to support short, frequent practice between sessions
NDIS funding
Whether CAS meets NDIS access criteria depends on its severity, persistence, and functional impact; a speech pathologist's assessment supports an access request. If approved, speech therapy is funded under Capacity Building — Improved Daily Living. For families without NDIS funding, sessions are private-pay at the NDIS rate.
What a Hey Sprout session looks like
Sessions run online via secure video. Because CAS depends on frequent practice, we coach parents to run short, structured practice between sessions — that high-repetition home practice is part of what makes therapy work. We hold your slot before asking for any NDIS or plan-manager details.
Frequently asked questions
How is CAS different from other speech difficulties?
Most speech sound difficulties are about learning the rules of sounds, or physically producing a sound. CAS is a motor-planning problem — the child knows what they want to say, but the brain has trouble coordinating the precise movement sequences for speech. That difference matters, because it changes the therapy approach.
What are the signs?
Inconsistent errors on the same word, groping for sounds, difficulty stringing syllables together, trouble with longer or more complex words, and speech that's hard to understand. A speech pathologist makes the diagnosis through careful assessment — it's often confused with other speech sound disorders.
What treatment works?
CAS needs frequent, intensive, one-to-one speech therapy that focuses on movement and lots of practice. Evidence-based approaches include the Nuffield programme (NDP3) and Rapid Syllable Transition Treatment (ReST, developed in Australia). It's repetition-heavy by design.
Can it be treated online?
Yes — speech pathology for CAS can be delivered effectively via telehealth, with parents coached to support the high-frequency practice that CAS requires between sessions.
Does Hey Sprout diagnose and treat CAS?
Yes. Differential diagnosis of motor speech disorders and CAS treatment are specialist speech pathology. We assess carefully, choose an evidence-based approach, and coach parents for the frequent practice CAS needs.

Autism (Level 1 and Level 2) in children
Autism is a lifelong neurodevelopmental difference. Level 1 and Level 2 children typically benefit from speech, OT, and psychology support — and most are NDIS-eligible.
Cerebral palsy — therapy support for children
Cerebral palsy affects movement and posture. Goal-directed OT and speech therapy build independence and communication, online and coordinated with your team.
Down syndrome — therapy support for children
Children with Down syndrome thrive with early, consistent therapy. Speech and OT build communication and daily-living skills, online and parent-coached.
Dyslexia in children
Dyslexia is a common, lifelong difficulty with reading and spelling. With structured-literacy support, children with dyslexia learn to read and thrive.
