The importance of deep speech phenotyping for neurodevelopmental and genetic disorders: a conceptual review / Karen V. CHENAUSKY in Journal of Neurodevelopmental Disorders, 14 (2022)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 14 (2022) Titre : The importance of deep speech phenotyping for neurodevelopmental and genetic disorders: a conceptual review Type de document : texte imprimé Auteurs : Karen V. CHENAUSKY, Auteur ; Helen TAGER-FLUSBERG, Auteur Langues : Anglais (eng) Mots-clés : Apraxias/genetics  Child  Humans  Language  Language Development Disorders/complications/genetics  Speech  Speech Disorders/genetics/psychology  Childhood apraxia of speech  Motor speech disorders  Phenotype  Speech sound disorders Index. décimale : PER Périodiques Résumé : BACKGROUND: Speech is the most common modality through which language is communicated, and delayed, disordered, or absent speech production is a hallmark of many neurodevelopmental and genetic disorders. Yet, speech is not often carefully phenotyped in neurodevelopmental disorders. In this paper, we argue that such deep phenotyping, defined as phenotyping that is specific to speech production and not conflated with language or cognitive ability, is vital if we are to understand how genetic variations affect the brain regions that are associated with spoken language. Speech is distinct from language, though the two are related behaviorally and share neural substrates. We present a brief taxonomy of developmental speech production disorders, with particular emphasis on the motor speech disorders childhood apraxia of speech (a disorder of motor planning) and childhood dysarthria (a set of disorders of motor execution). We review the history of discoveries concerning the KE family, in whom a hereditary form of communication impairment was identified as childhood apraxia of speech and linked to dysfunction in the FOXP2 gene. The story demonstrates how instrumental deep phenotyping of speech production was in this seminal discovery in the genetics of speech and language. There is considerable overlap between the neural substrates associated with speech production and with FOXP2 expression, suggesting that further genes associated with speech dysfunction will also be expressed in similar brain regions. We then show how a biologically accurate computational model of speech production, in combination with detailed information about speech production in children with developmental disorders, can generate testable hypotheses about the nature, genetics, and neurology of speech disorders. CONCLUSIONS: Though speech and language are distinct, specific types of developmental speech disorder are associated with far-reaching effects on verbal communication in children with neurodevelopmental disorders. Therefore, detailed speech phenotyping, in collaboration with experts on pediatric speech development and disorders, can lead us to a new generation of discoveries about how speech development is affected in genetic disorders.

Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration / Julia R. IRWIN in Journal of Autism and Developmental Disorders, 52-1 (January 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-1 (January 2022) . - p.28-37 Titre : Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration Type de document : texte imprimé Auteurs : Julia R. IRWIN, Auteur ; Trey AVERY, Auteur ; Daniel KLEINMAN, Auteur ; Nicole LANDI, Auteur Article en page(s) : p.28-37 Langues : Anglais (eng) Mots-clés : Auditory Perception  Autism Spectrum Disorder  Child  Cues  Evoked Potentials  Humans  Speech  Speech Perception  Visual Perception  Audiovisual  Autism  Phonemic restoration Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual processing in typically developing children and in children with autism spectrum disorder. Video of a speaker saying the syllable /ba/ was paired with (1) a synthesized /ba/ or (2) a synthesized syllable derived from /ba/ in which auditory cues for the consonant were substantially weakened, thereby sounding more like /a/. The auditory stimuli are easily discriminable; however, in the context of a visual /ba/, the auditory /a/ is typically perceived as /ba/, producing a visual phonemic restoration. Only children with ASD showed a large /ba/-/a/ discrimination response in the presence of a speaker producing /ba/, suggesting reduced influence of visual speech.

Face-viewing patterns predict audiovisual speech integration in autistic children / Shuyuan FENG in Autism Research, 14-12 (December 2021)  

Public ISBD [article]  inAutism Research > 14-12 (December 2021) . - p.2592-2602 Titre : Face-viewing patterns predict audiovisual speech integration in autistic children Type de document : texte imprimé Auteurs : Shuyuan FENG, Auteur ; Haoyang LU, Auteur ; Quan WANG, Auteur ; Tianbi LI, Auteur ; Jing FANG, Auteur ; Lihan CHEN, Auteur ; Li YI, Auteur Année de publication : 2021 Article en page(s) : p.2592-2602 Langues : Anglais (eng) Mots-clés : Acoustic Stimulation  Autism Spectrum Disorder/complications  Autistic Disorder/complications  Child  Child, Preschool  Female  Humans  Mouth  Speech  Speech Perception  Visual Perception  McGurk effect  atypical face-viewing patterns  audiovisual speech integration  autistic children  eye movements Index. décimale : PER Périodiques Résumé : Autistic children show audiovisual speech integration deficits, though the underlying mechanisms remain unclear. The present study examined how audiovisual speech integration deficits in autistic children could be affected by their looking patterns. We measured audiovisual speech integration in 26 autistic children and 26 typically developing (TD) children (4- to 7-year-old) employing the McGurk task (a videotaped speaker uttering phonemes with her eyes open or closed) and tracked their eye movements. We found that, compared with TD children, autistic children showed weaker audiovisual speech integration (i.e., the McGurk effect) in the open-eyes condition and similar audiovisual speech integration in the closed-eyes condition. Autistic children viewed the speaker's mouth less in non-McGurk trials than in McGurk trials in both conditions. Importantly, autistic children's weaker audiovisual speech integration could be predicted by their reduced mouth-looking time. The present study indicated that atypical face-viewing patterns could serve as one of the cognitive mechanisms of audiovisual speech integration deficits in autistic children. LAY SUMMARY: McGurk effect occurs when the visual part of a phoneme (e.g., "ga") and the auditory part of another phoneme (e.g., "ba") uttered by a speaker were integrated into a fused perception (e.g., "da"). The present study examined how McGurk effect in autistic children could be affected by their looking patterns for the speaker's face. We found that less looking time for the speaker's mouth in autistic children could predict weaker McGurk effect. As McGurk effect manifests audiovisual speech integration, our findings imply that we could improve audiovisual speech integration in autistic children by directing them to look at the speaker's mouth in future intervention.

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.

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.
