What describes the primary goal used to indicate therapy success in AOS?

• A. Faster speech rate with reduced articulation.
• B. Longer utterances with consistent grammatical structure but uncertain sequencing.
• C. Improved intelligibility and consistent production of longer, more complex utterances with accurate sequencing.
• D. Greater use of slang with preserved articulation.

Answer: (C)

In motor speech apraxia therapy, success is most clearly seen when the speaker becomes more intelligible and can produce longer, more complex utterances with accurate sequencing. This shows that the motor planning and programming for speech are becoming more precise, allowing longer phrases to be articulated smoothly and with the correct order of sounds and syllables.

Faster rate with reduced articulation often decreases intelligibility, so simply speaking more quickly without clear articulation isn’t a strong indicator of real progress. Longer utterances are valuable, but if the sequencing of sounds is uncertain, the overall intelligibility may still be poor, which means it doesn’t fully capture meaningful improvement. Using slang, while sometimes natural, doesn’t reflect a goal tied to improving motor planning or intelligibility, and isn’t a standard measure of therapy success.

So the best description of the primary goal is improved intelligibility paired with the ability to produce longer, more complex utterances that are sequenced accurately.
