A subset of utterances were low-pass filtered and rated for differences in intonation, speech rate, and rhythm. Listener ratings were minimally related to acoustic measures, underscoring the complexity of atypical prosody in ASD. Acoustic analyses revealed greater utterance-final fundamental frequency excursion size and slower speech rate in the ASD group. Slower speech rate was also evident in the ASD parent group, particularly parents with the broad autism phenotype. Overlapping prosodic differences in ASD and ASD Parent groups suggest that prosodic differences may constitute an important phenotype contributing to ASD features and index genetic liability to ASD among first-degree relatives.

Temporal Coordination and Prosodic Structure in Autism Spectrum Disorder: Timing Across Speech and Non-speech Motor Domains / Kathryn FRANICH in Journal of Autism and Developmental Disorders, 51-8 (August 2021)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 51-8 (August 2021) . - p.2929-2949 Titre : Temporal Coordination and Prosodic Structure in Autism Spectrum Disorder: Timing Across Speech and Non-speech Motor Domains Type de document : texte imprimé Auteurs : Kathryn FRANICH, Auteur ; Hung Yat WONG, Auteur ; Alan C.L. YU, Auteur ; Carol K.S. TO, Auteur Article en page(s) : p.2929-2949 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/complications/psychology  Female  Humans  Male  Speech/physiology  Speech Disorders/complications/psychology  Speech Perception/physiology  Time Perception/physiology  Young Adult  Autism  Motor control  Prosody  Speech timing  Temporal processing Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and normal nonverbal IQ and matched controls. Results indicate similar group results for prosodic grouping patterns, but significant differences in relative timing and longer syllable durations at phrase ends for the ASD group. Variability on the speech task was significantly correlated with variability on the drumming task, consistent with the view that impairment in both speech and non-speech motor domains can be linked with deficits in temporal processing.
