Autistic adults are often perceived as having an atypical speech. The acoustic characteristics of these impressions prove surprisingly difficult to delineate, but one feature that does robustly emerge across different studies is higher pitch (F0 values) in autistic versus neurotypical individuals. However, there is no clear explanation why…

The current study investigated whether the difficulty in finding group differences in prosody between speakers with autism spectrum disorder (ASD) and neurotypical (NT) speakers might be explained by identifying different acoustic profiles of speakers which, while still perceived as atypical, might be characterized by different acoustic qualities.…

Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal…

As an information-bearing auditory attribute of sound, pitch plays a crucial role in the perception of speech and music. Studies examining pitch processing in autism spectrum disorder have produced equivocal results. To understand this discrepancy from a mechanistic perspective, we used a novel data-driven method, the reverse-correlation paradigm,…

Face masks affect the transmission of speech and obscure facial cues. Here, we examine how this reduction in acoustic and facial information affects a listener's understanding of speech prosody. English sentence pairs that differed in their intonational (statement/question) and emotional (happy/sad) prosody were created. These pairs were recorded…

Atypical expressive prosody is reported as a consistent challenge for individuals with Autism Spectrum Disorder (ASD) and is associated with a broad set of clinical impairments including perceptions of oddness from others. Theories of atypical prosody in ASD have attributed these impairments to the broader symptoms of ASD, particularly in the…
