A Population-Based Study
Dimitri A. Christakis,Jeffrey A. Richards,Frederick J. Zimmerman,Michelle M. Garrison,Dongxin Xu,Umit Yapanel +5 more
TL;DR: In this article, a software program incorporating automatic speech-identification technology processed the recorded file to analyze the sounds the children were exposed to and the sounds they made, and a conditional linear regression was used to determine the association between audible television and the outcomes of interest.

Teaching by Listening: The Importance of Adult-Child Conversations to Language Development
Frederick J. Zimmerman,Jill Gilkerson,Jeffrey A. Richards,Dimitri A. Christakis,Dongxin Xu,Sharmistha Gray,Umit Yapanel +6 more
TL;DR: Television exposure is not independently associated with child language development when adult-child conversations are controlled, but adult- child conversations are robustly associated with healthy language development.
Journal ArticleDOI
Audible Television and Decreased Adult Words, Infant Vocalizations, and Conversational Turns: A Population-Based Study
Dimitri A. Christakis,Jill Gilkerson,Jeffrey A. Richards,Frederick J. Zimmerman,Michelle M. Garrison,Dongxin Xu,Sharmistha Gray,Umit Yapanel +7 more
TL;DR: Audible television is associated with decreased exposure to discernible human adult speech and decreased child vocalizations, which may explain the association between infant television exposure and delayed language development.
Journal ArticleDOI
Automated vocal analysis of naturalistic recordings from children with autism, language delay, and typical development.
D. K. Oller,Partha Niyogi,Sharmistha Gray,Jeffrey A. Richards,Jill Gilkerson,Dongxin Xu,Umit Yapanel,Steven F. Warren +7 more
TL;DR: The first automated approach implemented is not only able to track children's development on acoustic parameters known to play key roles in speech, but also is able to differentiate vocalizations from typically developing children and children with autism or language delay.
Journal ArticleDOI
A Social Feedback Loop for Speech Development and Its Reduction in Autism
TL;DR: Analyzing the microstructure of child-adult interaction during naturalistic, daylong, automatically labeled audio recordings of children with and without autism found that an adult was more likely to respond when the child’s vocalization was speech related rather than not speech related.
