Effects of Audiovisual Asynchrony on Speech Intelligibility in Typically Hearing Adults and Cochlear Implant Users

Typically hearing listeners benefit from multisensory integration over a broader range of speech asynchronies than CI users. Interestingly, at extreme asynchronies, CI users appear to be impaired by visual speech cues compared to typically hearing individuals, suggesting that they may attempt to use visual speech cues to inform intelligibility even when they occur outside of the range of asynchronies over which integration typically occurs. These findings align with literature on increased visual bias in CI users and raise questions regarding potential compensatory mechanisms for speech intelligibility.
