Inefficiencies in translation in AOS lead to distortions in what aspects of speech?

• A. Distortions in intra- and inter-articulator temporal and spatial aspects including segmental and prosodic features
• B. Only distortions in pitch
• C. Only distortions in loudness
• D. Only distortions in syllable count

Answer: (A)

In apraxia of speech, the planning-to-execution process falters, so the brain’s motor plan for moving the speech organs doesn’t map cleanly onto the muscles. This shows up as problems with both when and where the articulators move, across both individual sounds and the rhythm of speech. You can see errors that reflect timing within a single articulator (intra-articulator) and between multiple articulators (inter-articulator), as well as distortions in where the lips, tongue, and jaw end up during production. Because these issues span how sounds are formed (segmental features) and how speech is paced and emphasized (prosodic features), the distortions cover a broad range, not just pitch, loudness, or syllable count. That broader, combined impact on temporal and spatial aspects of articulation—across segmental and prosodic features—best captures what inefficiencies in translation cause in AOS.
