Childhood Apraxia of Speech (CAS)

Childhood Apraxia of Speech (CAS)

CAS in Younger Children

  • Nonverbal
  • Quiet during play
  • Reliance on gestures
  • Vowel errors = undifferentiated (centralized) vowels. For example, dad sounds like “did”
  • Inconsistent hypernasality

CAS in Older Children

  • Persistence of patterned (phonological) errors at older ages (e.g., fronting). Child continues to say “tootie” for cookie, even though he can produce a /k/ sound
  • Difficult to understand in connected speech
  • Minimal progress despite years of therapy
  • Difficulties with mutisyllabic word productions (e.g., child can say “butter” and “cup” but has difficulty blending the words together to make “buttercup”)
  • Distorted consonants/distorted consonant substitution errors (typically in severe cases) – inconsistent hypernasality, trial and error groping
  • Prosodic abnormalities (persists in severe cases). Child may have difficulty gauging an “indoor” versus an “outdoor” voice
  • Ongoing articulation errors (ie., /r/, /s/, /l/), especially in multisyllabic word productions and connected speech (persists in milder cases)
