PFORDRESHER, Auteur ; Cunmei JIANG, Auteur ; Fang LIU, Auteur Article en page(s) : p.408-423 Langues : Anglais (eng) Mots-clés : acoustics  autism  song  speech  vocal imitation Index. décimale : PER Périodiques Résumé : Vocal imitation in English-speaking autistic individuals has been shown to be atypical. Speaking a tone language such as Mandarin facilitates vocal imitation skills among non-autistic individuals, yet no studies have examined whether this effect holds for autistic individuals. To address this question, we compared vocal imitation of speech and song between 33 autistic Mandarin speakers and 30 age-matched non-autistic peers. Participants were recorded while imitating 40 speech and song stimuli with varying pitch and duration patterns. Acoustic analyses showed that autistic participants imitated relative pitch (but not absolute pitch) less accurately than non-autistic participants for speech, whereas for song the two groups performed comparably on both absolute and relative pitch matching. Regarding duration matching, autistic participants imitated relative duration (inter-onset interval between consecutive notes/syllables) less accurately than non-autistic individuals for both speech and song, while their lower performance on absolute duration matching of the notes/syllables was presented only in the song condition. These findings indicate that experience with tone languages does not mitigate the challenges autistic individuals face in imitating speech and song, highlighting the importance of considering the domains and features of investigation and individual differences in cognitive abilities and language backgrounds when examining imitation in autism. Lay abstract Atypical vocal imitation has been identified in English-speaking autistic individuals, whereas the characteristics of vocal imitation in tone-language-speaking autistic individuals remain unexplored. By comparing speech and song imitation, the present study reveals a unique pattern of atypical vocal imitation across speech and music domains among Mandarin-speaking autistic individuals. The findings suggest that tone language experience does not compensate for difficulties in vocal imitation in autistic individuals and extends our understanding of vocal imitation in autism across different languages.

Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation / Lifang WANG in Autism Research, 14-11 (November 2021)  

Public ISBD [article]  inAutism Research > 14-11 (November 2021) . - p.2355-2372 Titre : Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation Type de document : texte imprimé Auteurs : Lifang WANG, Auteur ; Peter Q. PFORDRESHER, Auteur ; Cunmei JIANG, Auteur ; Fang LIU, Auteur Article en page(s) : p.2355-2372 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/complications  Child  Humans  Imitative Behavior  Singing  Speech  Voice  Asd  duration  pitch  song  speech  vocal imitation Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation. However, few studies have identified clear quantitative characteristics of vocal imitation in ASD. This study investigated imitation of speech and song in English-speaking individuals with and without ASD and its modulation by age. Participants consisted of 25 autistic children and 19 autistic adults, who were compared to 25 children and 19 adults with typical development matched on age, gender, musical training, and cognitive abilities. The task required participants to imitate speech and song stimuli with varying pitch and duration patterns. Acoustic analyses of the imitation performance suggested that individuals with ASD were worse than controls on absolute pitch and duration matching for both speech and song imitation, although they performed as well as controls on relative pitch and duration matching. Furthermore, the two groups produced similar numbers of pitch contour, pitch interval-, and time errors. Across both groups, sung pitch was imitated more accurately than spoken pitch, whereas spoken duration was imitated more accurately than sung duration. Children imitated spoken pitch more accurately than adults when it came to speech stimuli, whereas age showed no significant relationship to song imitation. These results reveal a vocal imitation deficit across speech and music domains in ASD that is specific to absolute pitch and duration matching. This finding provides evidence for shared mechanisms between speech and song imitation, which involves independent implementation of relative versus absolute features. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation of actions and gestures. Characteristics of vocal imitation in ASD remain unclear. By comparing speech and song imitation, this study shows that individuals with ASD have a vocal imitative deficit that is specific to absolute pitch and duration matching, while performing as well as controls on relative pitch and duration matching, across speech and music domains.
