Product Description:

Speech acoustic-prosodic features were semi-automatically derived from segments of semi-structured interviews (Autism Diagnostic Observation Schedule; ADOS) with 28 children previously diagnosed with ASD. Prosody was quantified in terms of intonation, volume, rate, and voice quality. Automatically extracted speech features demonstrated prosodic characteristics of dyadic interactions. As rated ASD severity increased, both participants demonstrated effects for turn-end pitch slope, and both spoke with atypical voice quality. The psychologists acoustic cues predicted the childs symptom severity better than the childs acoustic cues.
