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.

Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children’s speech to one another and foster their language abilities and how these processes may vary in children with hearing loss. A team of researchers from the University of Miami used new objective measurement approaches to identify and quantify children’s vocalizations during social contact, as determined by children’s proximity and mutual orientation.
In this Developmental Science journal article, Daniel Messinger, Lynn Perry, et al., studied phonemic diversity and how it affects language development in preschool children. Their results highlighted a specific feature of the classroom language environment—phonemic diversity—as a promising correlate of children’s developing language capacities.
This study objectively measured associations between children’s peer vocal interactions and assessed language abilities in inclusion classrooms for children with autism spectrum disorder (ASD) and their peers. All children benefited from peers talking to them, but children with ASD were less central to classroom speech networks than were typically developing children.
