Diagnostic evaluations for ASD typically include the autism diagnostic observation schedule (ADOS-2), a semi-structured assessment composed of a series of social presses. The current study examined associations between concurrent objective features of child vocalizations during the ADOS-2 and examiner-rated autism symptom severity. The sample included 66 children (49 male; M = 40months, SD = 10.58) evaluated in a university-based clinic, 61 of whom received an ASD diagnosis. Research reliable administration of the ADOS-2 provided social affect (SA) and restricted and repetitive behavior (RRB) calibrated severity scores (CSS). Audio was recorded from examiner-worn eyeglasses during the ADOS-2 and child and adult speech were differentiated with LENA SP Hub. PRAAT was used to ascertain acoustic features of the audio signal, specifically the mean fundamental vocal frequency (F0) of LENA-identified child speech-like vocalizations (those with phonemic content), child cry vocalizations, and adult speech. Sphinx-4 was employed to estimate child and adult phonological features indexed by the average consonant and vowel count per vocalization. More than a quarter of the variance in ADOS-2 RRB CSS was predicted by the combination of child phoneme count per vocalization and child vocalization F0. Findings indicate that both acoustic and phonological features of child vocalizations are associated with expert clinician ratings of autism symptom severity. LAY SUMMARY: Determination of the severity of autism spectrum disorder is based in part on expert (but subjective) clinician observations during the ADOS-2. Two characteristics of child vocalizations-a smaller number of speech-like sounds per vocalization and higher pitched vocalizations (including cries)-were associated with greater autism symptom severity. The results suggest that objectively ascertained characteristics of children's vocalizations capture variance in children's restricted and repetitive behaviors that are reflected in clinician severity indices.

Out of the mouths of babes: vocal production in infant siblings of children with ASD / Rhea PAUL in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.588-598 Titre : Out of the mouths of babes: vocal production in infant siblings of children with ASD Type de document : texte imprimé Auteurs : Rhea PAUL, Auteur ; Yael FUERST, Auteur ; Gordon RAMSAY, Auteur ; Kasia CHAWARSKA, Auteur ; Ami KLIN, Auteur Année de publication : 2011 Article en page(s) : p.588-598 Langues : Anglais (eng) Mots-clés : Autism  speech  vocalization  infant siblings Index. décimale : PER Périodiques Résumé : Background:  Younger siblings of children with autism spectrum disorders (ASD) are at higher risk for acquiring these disorders than the general population. Language development is usually delayed in children with ASD. The present study examines the development of pre-speech vocal behavior in infants at risk for ASD due to the presence of an older sibling with the disorder. Methods:  Infants at high risk (HR) for ASD and those at low risk, without a diagnosed sibling (LR), were seen at 6, 9, and 12 months as part of a larger prospective study of risk for ASD in infant siblings. Standard clinical assessments were administered, and vocalization samples were collected during play with mother and a standard set of toys. Infant vocal behavior was recorded and analyzed for consonant inventory, presence of canonical syllables, and of non-speech vocalizations, in a cross-sectional design. Children were seen again at 24 months for provisional diagnosis. Results:  Differences were seen between risk groups for certain vocal behaviors. Differences in vocal production in the first year of life were associated with outcomes in terms of autistic symptomotology in the second year. Conclusions:  Early vocal behavior is a sensitive indicator of heightened risk for autistic symptoms in infants with a family history of ASD.

Comparative analysis of vocal communication and atypicality in mandarin-speaking children with autism spectrum disorder, developmental delay, and typical development / Min LIU in Research in Autism Spectrum Disorders, 119 (January 2025)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 119 (January 2025) . - p.102513 Titre : Comparative analysis of vocal communication and atypicality in mandarin-speaking children with autism spectrum disorder, developmental delay, and typical development Type de document : texte imprimé Auteurs : Min LIU, Auteur ; Yanxia WANG, Auteur ; Xinyu HU, Auteur ; Mudi SUN, Auteur ; Lu QU, Auteur ; Xuling HAN, Auteur ; Hang ZHAO, Auteur ; Haidan LU, Auteur ; Qiaoyun LIU, Auteur Article en page(s) : p.102513 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Communication  Vocalization  Vocal atypicality  Area under the curve  Developmental disorder Index. décimale : PER Périodiques Résumé : Purpose The current study aimed to examine the similarities and differences in vocal characteristics between Mandarin-speaking 36-72-month-old children with autism spectrum disorder (ASD), children with developmental delay (DD), and typically developing (TD) children. Methods We analyzed vocal characteristics during parent-child free play. Video and audio samples were collected from 21 children with ASD, 18 children with DD matched groupwise for developmental level, and 15 TD children matched groupwise for chronological age. Results Compared to children in the DD and TD groups, children with ASD exhibited a significantly higher proportion of nonspeech vocalizations (NSV, p<0.01), atypical vocalizations (ATY, p<0.001), noncommunicative vocalizations (NCV, p<0.001), and no response to others (NR, p<0.001). These four metrics were significantly correlated with children s performance on the developmental evaluation and intelligence test. Receiver operating characteristic analyses indicated that the area under the curve (AUC) ranged from 0.871-0.978, with moderate accuracy, when using these four metrics to differentiate between children with ASD and TD children; this value improved to 1.000 with high accuracy when combining the four metrics. The AUC ranged from 0.747-0.820 when using the four metrics to differentiate children with ASD from those with DD and improved to 0.857 when combining the four metrics. Conclusion These preliminary data suggest that vocal communication and vocal atypicality may be unique features of children with minimally verbal ASD and that the four metrics-NSV, ATY, NCV, and NR-have the potential to be ASD behavioral markers in screening and diagnosis.

Enhanced Memory for Vocal Melodies in Autism Spectrum Disorder and Williams Syndrome / Michael W. WEISS in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1127-1133 Titre : Enhanced Memory for Vocal Melodies in Autism Spectrum Disorder and Williams Syndrome Type de document : texte imprimé Auteurs : Michael W. WEISS, Auteur ; Megha SHARDA, Auteur ; Miriam D. LENSE, Auteur ; Krista L. HYDE, Auteur ; Sandra E. TREHUB, Auteur Article en page(s) : p.1127-1133 Langues : Anglais (eng) Mots-clés : Adolescent  Adult  Auditory Perception  Autism Spectrum Disorder/complications  Child  Humans  Music  Voice  Williams Syndrome/complications  Williams syndrome  autism  memory  vocalization Index. décimale : PER Périodiques Résumé : Adults and children with typical development (TD) remember vocal melodies (without lyrics) better than instrumental melodies, which is attributed to the biological and social significance of human vocalizations. Here we asked whether children with autism spectrum disorder (ASD), who have persistent difficulties with communication and social interaction, and adolescents and adults with Williams syndrome (WS), who are highly sociable, even indiscriminately friendly, exhibit a memory advantage for vocal melodies like that observed in individuals with TD. We tested 26 children with ASD, 26 adolescents and adults with WS of similar mental age, and 26 children with TD on their memory for vocal and instrumental (piano, marimba) melodies. After exposing them to 12 unfamiliar folk melodies with different timbres, we required them to indicate whether each of 24 melodies (half heard previously) was old (heard before) or new (not heard before) during an unexpected recognition test. Although the groups successfully distinguished the old from the new melodies, they differed in overall memory. Nevertheless, they exhibited a comparable advantage for vocal melodies. In short, individuals with ASD and WS show enhanced processing of socially significant auditory signals in the context of music. LAY SUMMARY: Typically developing children and adults remember vocal melodies better than instrumental melodies. In this study, we found that children with Autistic Spectrum Disorder, who have severe social processing deficits, and children and adults with Williams syndrome, who are highly sociable, exhibit comparable memory advantages for vocal melodies. The results have implications for musical interventions with these populations.
