Audiovisual Mandarin Lexical Tone Perception in Quiet and Noisy Contexts: The Influence of Visual Cues and Speech Rate.

This study provided compelling evidence showing that integrated audiovisual information plays a vital role not only in improving lexical tone perception in noise but also in modulating the effects of speech rate on Mandarin tone perception in quiet for native listeners. Our findings, supporting the theory of embodied cognition, are implicational for speech and hearing rehabilitation among both young and old clinical populations.
