What improvement pattern is often observed with cued or model-based therapy in AOS?

• A. No improvement with cueing.
• B. Improvements are limited to rate, not accuracy.
• C. Therapy benefits only when goals are cognitive, not motor.
• D. Improved accuracy and fluency when provided with model or cueing, with repetition and cues facilitating motor relearning.

Answer: (D)

Providing an external model or cues helps the person with apraxia of speech plan and execute the correct sequence of articulatory movements. The model gives a concrete template for how sounds should be produced, including placement, timing, and prosody, which reduces errors during speech attempts. Repetition with those cues reinforces the motor plan, supporting motor relearning so accuracy improves alongside fluency. Over time, practice with model-based cues can become more automatic, but the initial and strongest gains are seen in both more accurate articulation and smoother, more fluent speech when guidance is present. This pattern aligns with how modeling and cueing support motor learning in AOS, rather than showing no improvement or limits to rate alone.
