Final answer:
The ASHA 2007 document defines three core characteristics of CAS as inconsistent errors on consonants and vowels, difficulty with sound transitions, and inappropriate prosody in stress realization.
Step-by-step explanation:
Characteristics of Childhood Apraxia of Speech (CAS)
The American Speech-Language-Hearing Association (ASHA) 2007 document outlines the three core characteristics of CAS. These characteristics are:
- Inconsistent errors on consonants and vowels in repeated productions of syllables or words.
- The difficulty with coarticulatory transitions between sounds and syllables.
- Inappropriate prosody, especially in the realization of lexical or phrasal stress.
CAS is a motor speech disorder that makes it hard for children to speak. ASHA's document helps in the diagnosis and treatment by providing these core characteristics that define CAS. Clinical professionals use this criterion to assess and plan intervention strategies for individuals with this disorder.
