Purpose: The authors sought to investigate interactions among intelligibility-enhancing speech cues (i.e., semantic context, clearly produced speech, and visual information) across a range of masking conditions.
The study explores how visual cues affect native English speakers' understanding of speech from nonnative Korean speakers.
It finds that native listeners perceive Korean-accented speech as more accented when visual cues are present, compared to when they only hear the audio.
The research suggests that visual biases among listeners can hinder their ability to integrate audiovisual information effectively, particularly with nonnative accents.
