A 3-year-old child was seen at the speech-and-language clinic for a speech assessment to address teacher and parent concerns about speech intelligibility. During the initial interview and observation, the SLP noted that the child exhibited inconsistent errors of vowel and consonant production during repetitive speech tasks, inappropriate prosody, and prolongations of speech sounds. The SLP chooses an assessment to determine the presence of childhood apraxia of speech (CAS). Which of the following procedures is most appropriate for this type of assessment?
A. Analyzing place, manner, and voicing of all consonant sounds at the word level.
B. Evaluating fluency of speech during structured and unstructured conversational activities.
C. Testing stimulability of later-developing speech sounds in multiple phonetic contexts.
D. Determining speech production in a variety of syllables-to-sentence combinations.
