A Visual Speech Intelligibility Benefit Based on Speech Rhythm.

ABSTRACT: This study examined whether visual speech provides speech-rhythm information that perceivers can use in speech perception. This was tested by using speech that naturally varied in the familiarity of its rhythm. Thirty Australian English L1 listeners performed a speech perception in noise task with English sentences produced by three speakers: an English L1 speaker (familiar rhythm); an experienced English L2 speaker who had a weak foreign accent (familiar rhythm), and an inexperienced English L2 speaker who had a strong foreign accent (unfamiliar speech rhythm). The spoken sentences were presented in three conditions: Audio-Only (AO), Audio-Visual with mouth covered (AVm), and Audio-Visual (AV). Speech was best recognized in the AV condition regardless of the degree of foreign accent. Howe
