What is Childhood Apraxia of Speech?

Childhood Apraxia of Speech (CAS) is a disorder that affects a child’s’ clarity or articulation of speech sounds. When a child is often very difficult to understand and has limited consonants and vowels, a speech pathologist may be concerned that they have CAS. It is also known as Developmental Apraxia of Speech.

CAS can occur in conjunction with other genetic conditions (e.g. Autism) and also occur as an idiopathic speech disorder; meaning that the child does not present with any neurological abnormalities or other developmental conditions.

Below are the three characteristics that differentiate CAS from other speech sound disorders as reported by the American Speech-Language-Hearing Association (ASHA):

  • Inconsistent errors with consonants and vowels (the child may say the same word in different ways when asked to repeat the word multiple times).
  • A difficulty with the transitions between sounds or syllables in words (resulting in long pauses between sounds/ syllables which impacts the clarity of a child’s speech.)
  • A difficulty with using correct intonation and stress when speaking (e.g. placing equal stress on all syllables within a word which can result in the child’s speech sounding monotone or flat).

The presentation of CAS is not limited to the above characteristics. For further information on the prevalence, diagnosis, symptoms and treatment of CAS, see the links below.
