Which sign is commonly observed when producing consonant clusters or multisyllabic words in AOS?

• A. Segmentation and breakdowns with increasing errors as cluster complexity rises
• B. Uniform articulation with no errors
• C. Only vowel distortions
• D. Improved accuracy with clusters

Answer: (A)

In apraxia of speech, planning and programming the movements for speech become challenged, especially for harder sequences. The sign you’re looking for when producing consonant clusters or multisyllabic words is segmentation and breakdowns within the word that grow worse as the sequence gets more complex. This happens because coordinating several articulators in rapid, precise order demands more from the motor planning system; when that planning is impaired, elements tend to come apart, with hesitations, pauses, substitutions, or distortions appearing more often as the cluster or word length increases. In other words, the more complex the sequence, the more the speech tends to break down. This fits the characteristic pattern of AOS, where errors become more prominent with increased articulatory demand.
