Titre : Objective measurement of vocalizations in the assessment of autism spectrum disorder symptoms in preschool age children Type de document : Texte imprimé et/ou numérique Auteurs : Jacquelyn M. MOFFITT, Auteur ; Yeojin Amy AHN, Auteur ; Stephanie CUSTODE, Auteur ; Yudong TAO, Auteur ; Emilin MATHEW, Auteur ; Meaghan V. PARLADE, Auteur ; Melissa HALE, Auteur ; Jennifer DUROCHER, Auteur ; Michael ALESSANDRI, Auteur ; Lynn K. PERRY, Auteur ; Daniel S. MESSINGER, Auteur Article en page(s) : p.1665-1674 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/diagnosis Autistic Disorder Child Child, Preschool Humans Male audio processing objective measurement vocalization Index. décimale : PER Périodiques Résumé : Assessment of autism spectrum disorder (ASD) relies on expert clinician observation and judgment, but objective measurement tools have the potential to provide additional information on ASD symptom severity. 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; MÂ =Â 40months, SDÂ =Â 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.

Titre : Out of the mouths of babes: vocal production in infant siblings of children with ASD Type de document : Texte imprimé et/ou numérique 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.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02332.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=121

Titre : Enhanced Memory for Vocal Melodies in Autism Spectrum Disorder and Williams Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : M. W. WEISS, Auteur ; M. SHARDA, Auteur ; M.

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.
