A Population-Based Study

TLDR

The study examines children’s exposure to audible television. Children wore digital recorders for up to 24 months, and their audio was processed by speech‑identification software and analyzed via conditional linear regression to assess the association between audible television exposure and outcomes such as adult word counts, child vocalizations, and conversational turns.

Abstract

Main Exposures: Audible television. Children wore a digital recorder on random days for up to 24 months. 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. Conditional linear regression was used to determine the association between audible television and the outcomes of interest. Outcome Measures: Adult word counts, child vocalizations, and child conversational turns.
