Atypical speech prosody is a hallmark feature of autism spec- trum disorder (ASD) that presents across the lifespan, but is difficult to reliably characterize qualitatively. Given the great heterogeneity of symptoms in ASD, an acoustic-based objec- tive measure would be vital for clinical assessment and inter- ventions. In this study, we investigate speech features in child- psychologist conversational samples, including: segmental and suprasegmental pitch dynamics, speech rate, coordination of prosodic attributes, and turn-taking. Data consist of 95 children with ASD as well as 81 controls with non-ASD developmental disorders. We demonstrate significant predictive performance using these features as well as interpret feature correlations of both interlocutors. The most robust finding is that segmen- tal and suprasegmental prosodic variability increases for both participants in interactions with children having higher ASD severity. Recommendations for future research towards a fully-automatic quantitative measure of speech prosody in neurode- velopmental disorders are discussed.
