Maturation of Speech-in-Speech Recognition for Whispered and Voiced Speech.

17 08 2022

DOI: 10.1044/2022_JSLHR-21-00620 PMID: 35868232

Two experiments evaluated development of speech-in-speech re... Listeners were 5- to 7-year-olds and adults with normal hearing. Targets were monosyllabic words organized into three-word sets that differ in vowel content. Maskers were two-talker or one-talker stre... Children performed more poorly than adults overall. For the two-talker masker, this age effect was smaller for the whispered target and masker than for the other three conditions. Children's SRTs in t... These results provide no compelling evidence that young school-age children and adults are differentially sensitive to the cues present in voiced and whispered speech.
