Differential diagnosis of apraxia of speech (AOS) is complicated by frequently co-occurring speech and language disorders. Auditoryperceptual measures may not adequately differentiate between disorders. This study adapted an acoustic analysis protocol developed for Parkinson's disease (PD). Preliminary results are positive, showing differences between individuals with AOS, PD, and healthy controls (HC).
