Childhood Apraxia of Speech (CAS) Therapy in Chennai | DARC

Childhood apraxia of speech (CAS) is a motor speech disorder — the child has difficulty planning and coordinating the movements needed to produce speech sounds, syllables, and words, even though the muscles themselves are not weak. It is not a language delay: children with CAS often understand language well but struggle significantly to express it verbally.

CAS is different from typical speech delay. A child with speech delay follows a slower but typical pattern of sound development. A child with CAS shows inconsistent errors, difficulty with longer words, unusual prosody (rhythm and stress of speech), and slow improvement with general speech therapy approaches not designed for motor speech.

Early signs include very limited babbling in infancy, first words arriving very late or not at all, inconsistent production of the same word on different attempts, difficulty imitating sounds or words, loss of words the child previously said, easier production of short simple sounds but difficulty combining them, and slow progress despite general speech support.

CAS is often diagnosed by a speech-language pathologist with specific motor speech experience. If your child is not talking and standard speech therapy has not produced expected progress, a CAS-specific evaluation is a reasonable next step.

CAS requires a different therapeutic approach from general speech delay. Motor speech therapy for CAS uses intensive, repetitive practice of specific movement sequences — not just vocabulary building or sound drills. The goal is to build the motor programmes the child needs to produce words reliably.

Frequency matters significantly. Children with CAS typically need more frequent sessions than children with general speech delay — 3–5 times per week is often recommended during intensive phases. Parent practice between sessions is equally important.

DARC's speech team, led by Vasudharany MSLP, includes experience with motor speech disorders including CAS. Assessment covers speech motor planning, phonological processing, language comprehension and expression, and AAC suitability — because many children with CAS benefit from AAC supports during the period before verbal communication becomes reliable.

The OT team is closely involved where CAS co-occurs with sensory processing difficulties, developmental delay, or autism — which is common. A coordinated OT-speech plan ensures all contributing factors are addressed.

Families in Chennai with concerns about CAS can book a speech assessment at DARC Ashok Nagar (+91 80151 52682) or Pallikaranai (+91 88705 29103). Bring video of the child attempting to speak at home — it provides useful information that clinic assessments sometimes miss.

If your child has already received a CAS diagnosis elsewhere, DARC's team can review the existing assessment and build a targeted speech motor programme.
