Childhood apraxia of speech, understood properly.
CAS is a motor speech planning disorder that needs a specific, intensive approach — not general articulation therapy. Getting the diagnosis right is the first step.
A planning problem, not a muscle problem
In CAS, a child's brain struggles to reliably plan and sequence the movements needed for speech , even though there's nothing wrong with the muscles themselves. This shows up as inconsistent errors on the same word said more than once, groping or effortful movements while trying to speak, and speech that gets harder as words get longer.
Why an accurate diagnosis matters
CAS is frequently under or over diagnosed because its features overlap with other speech sound disorders. Getting it right matters because the treatment approach is genuinely different , CAS responds best to frequent, intensive, carefully sequenced motor practice, not the drill and repeat approach used for other articulation difficulties.
Features that suggest CAS
These patterns, especially together, are worth a specialist assessment.
- The same word is said differently each time it's attempted
- Groping or visible effort while trying to find the right mouth position
- Speech gets noticeably harder as words or phrases get longer
- Difficulty imitating speech sounds on request, better than spontaneous speech
- Vowel errors, which are less common in other speech sound disorders
- Slow, effortful, or inconsistent rate and stress patterns in speech
If you recognise some of these signs, it may be helpful to discuss your child's communication with a qualified speech and language therapist. An initial discussion can help you understand whether further assessment or support would be appropriate.
How we treat CAS
Intensive practice
Frequent sessions with high numbers of correct movement repetitions.
Motor-planning approaches
Therapy methods specifically designed for planning, not just production.
Structured progression
Careful sequencing from simple to complex sound combinations.
AAC where useful
A reliable backup communication method while speech is being built.
Questions parents ask
What is childhood apraxia of speech (CAS)?+
CAS is a motor speech disorder — the brain has difficulty planning and coordinating the precise movements needed for speech, even though the muscles themselves work normally. It's a planning problem, not a muscle weakness problem, and it's different from a general speech delay.
How is CAS diagnosed?+
There's no single test — diagnosis is based on a pattern of specific features observed by a speech and language therapist experienced in motor speech disorders, often over more than one session, since some features only become clear as a child's speech develops.
How is CAS treated differently from a general speech delay?+
CAS needs frequent, intensive practice of speech movement sequences — usually more sessions per week than a typical speech delay — using approaches designed specifically for motor planning, not general articulation drills.
Will a child with CAS need AAC?+
Some do, especially younger children or those with more severe presentations, as a way to communicate reliably while speech is being built. AAC alongside CAS therapy is common and doesn't slow speech progress — the two work together.
