Audiovisual Speech Processing in Relationship to Phonological and Vocabulary Skills in First Graders.

ABSTRACT:

Purpose

It is generally accepted that adults use visual cues to improve speech intelligibility in noisy environments, but findings regarding visual speech benefit in children are mixed. We explored factors that contribute to audiovisual (AV) gain in young children's speech understanding. We examined whether there is an AV benefit to speech-in-noise recognition in children in first grade and if visual salience of phonemes influences their AV benefit. We explored if individual differences in AV speech enhancement could be explained by vocabulary knowledge, phonological awareness, or general psychophysical testing performance.

Method

Thirty-seven first graders completed online psychophysical experiments. We used an online single-interval, four-alternative forced-choice picture-
