Which cueing approach can improve intelligibility in AOS without changing underlying motor planning?

• A. Visual cues for timing
• B. Silent reading
• C. External pacing cues, such as metronome pacing or finger tapping
• D. Increase loudness

Answer: (C)

External pacing cues provide a timing scaffold that guides speech production. In apraxia of speech, the difficulty lies in the accurate timing and sequencing of articulatory movements, not in a complete loss of motor planning. A steady beat from a metronome or a simple rhythm like finger tapping gives the speaker a temporal frame to align each syllable and phoneme with, which helps steady rate, reduce variability, and smooth transitions between sounds. Because this approach offers guidance on timing without changing the underlying motor commands themselves, intelligibility improves while the motor plan remains the same. Other options don’t offer the same rhythmic structure: visual timing cues can help, but they’re not as proven for maintaining fluent timing; silent reading yields no audible speech; increasing loudness affects audibility rather than the timing and coordination of movements.
