Childhood Apraxia of Speech (CAS) is speech production disorder. It causes the child’s speech to be hard to understand. Children with CAS have trouble making speech sounds and blending sounds together to form words.

Children with CAS make even more errors on longer words and sentences. This makes the child’s speech harder to understand. A child with CAS may be able to make a sound or word correctly one time, but not be able to say it another time.

A child with CAS has a hard time putting the tongue, lips and jaw in the right position to make many speech sounds. Usually, the child with CAS does not have difficulty with non-speech oral movements such as chewing, licking, or swallowing. He may have problems with other motor skills such as cutting, coloring, or writing.

Difficultly with speech development may result in difficulties with language development as well as problems with reading and spelling.
