  • Limited babbling or cooing as an infant

  • Delayed first words

  • Difficulty imitating speech sounds or repeating words or phrases accurately

  • Inconsistent speech errors

  • Difficulty with longer or more complex words or phrases

  • Difficulty with multi-syllabic words

  • Slow and effortful speech, with pauses or hesitation between words or syllables

  • Not able to produce all the consonant and vowel sounds expected for their age

  • Substitution of similar sounds

  • Atypical intonation or stress (emphasis) in speech

  • Difficult to understand

  • Frustration at not being understood

what is Childhood Apraxia of Speech (CAS)?

What is Childhood Apraxia of Speech?

CAS is a motor speech disorder that affects a child's ability to plan and coordinate the movements needed for speech. The brain has difficulty coordinating the movements of the lips, tongue, jaw, and other speech muscles, resulting in unclear and often inconsistent speech sounds.

Children with CAS often have difficulty producing clear, consistent speech, making it difficult for others to understand them. Despite their speech difficulties, children with CAS may understand language very well and have cognitive abilities that are typical for their age.

How can we help kids with Childhood Apraxia of Speech (CAS)?

At Care Speech Pathology, our therapists play a crucial role in the assessment and treatment of CAS.


We will start by completing a comprehensive assessment to determine if your child has CAS, the severity and how it is impacting their ability to communicate. This assessment may include standardised tests, informal assessments, and observations of their speech in different contexts.


We can then plan individualised treatment for CAS based on your child’s specific strengths and needs. Treatment will use various strategies to address your child’s motor planning and coordination difficulties. Treatment will involve a lot of repetition but we can cater this to your child’s attention abilities. Sessions might work on making some words and phrases more automatic as well as practicing the use of intonation and stress.


We will also consider your child’s communication as a whole and if there is anything else we can be doing to support them. For example, it might be suitable for your child to use other means of communication to support them in expressing their message, such as Augmentative and Alternative Communication (AAC). AAC can be simple (e.g., a communication book) or a bit more advanced (e.g., a communication app). Often this is only needed temporarily as most children will be able to speak and be understood with the correct intensity of treatment. AAC can also support a child to develop their language and literacy skills while they continue developing their speech.
