Are errors of prosody in AOS frequently abnormal?

• A. Frequently abnormal
• B. Always normal
• C. Never observed
• D. Only in severe cases

Answer: (A)

Prosody reflects how speech is timed, stressed, and intoned, all of which hinge on precise motor planning. In apraxia of speech, the main problem is programming the sequence and timing of movements for speech. When that planning is disrupted, the timing and organization across syllables and words fall apart, so prosody often becomes abnormal. You’ll typically see a slowed, halting rhythm with uneven stress patterns, longer pauses between unit parts of speech, and sometimes a monotone or unpredictable pitch. Because producing natural prosody requires accurate motor sequencing, these prosodic disturbances are a common and noticeable feature in AOS, even though the exact presentation can vary from person to person.
