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.

Phonological Development in 3-6-Year-Old Mandarin-Speaking Children with Autism, Developmental Delays, and Typical Development / Min LIU in Journal of Autism and Developmental Disorders, 55-12 (December 2025)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 55-12 (December 2025) . - p.4312-4323 Titre : Phonological Development in 3-6-Year-Old Mandarin-Speaking Children with Autism, Developmental Delays, and Typical Development Type de document : texte imprimé Auteurs : Min LIU, Auteur ; Jinhe HAN, Auteur ; Yuexin ZHANG, Auteur ; Jieling WEN, Auteur ; Yanxia WANG, Auteur ; Xinyu HU, Auteur ; Mudi SUN, Auteur ; Lu QU, Auteur ; Xuling HAN, Auteur ; Lian XU, Auteur ; Hang ZHAO, Auteur ; Haidan LU, Auteur ; Qiaoyun LIU, Auteur Article en page(s) : p.4312-4323 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Research on the phonological development of children with autism spectrum disorder (ASD) has not yet reached consistent conclusions, and systematic studies from different language groups are needed. This study aimed to systematically investigate the characteristics of phonological development in 3-6 year-old Mandarin-speaking children with ASD. We analyzed 10 min speech samples from 21 children with ASD, 18 development level-matched children with developmental disorders (DD), and 15 chronological age-matched typically developing (TD) children during semi-structured parent-child free play based on Mandarin phonological features. The children with ASD had a significantly smaller inventory than those with TD on the initial and final inventories. The children with ASD had only a significantly smaller initial inventory than those with DD in Phases 2 and 4. Compared with TD children, children with ASD used a higher proportion of V1 and V1V2C and a smaller proportion of V1V2V3, CV1C, and CV1V2C. No significant differences existed between ASD and DD children in the proportion of any syllable structure, but V1V2V3, CV1, and CV1V2C numbers were significantly fewer than in DD children. Children with ASD were significantly greater than children with TD in the diversity of V1V2, CV1, and overall syllables. ASD children had significantly fewer different types of syllables in both V1V2C and CV1 than did DD children and significantly greater diversity in CV1 and overall syllables than did DD children. These preliminary data suggest that the gap between TD and ASD children’s language abilities increased with age, and this gap was reflected in initial, final, and syllable complexity and diversity. Children with DD and ASD showed similar language abilities, and children with DD showed detailed differences from those with ASD regarding initial, syllable complexity and diversity.
