Abstract
Research has indicated the important role that vision plays in face-to-face voice communication. This study was an attempt to quantify further the visual contribution to speech intelligibility in a high intensity noise environment in terms of the angle and distance from the listener to the speaker. Results indicated that (1) visual cues resulted in a significant increase in listener-intelligibility scores, (2) the angle at which the listeners observed the speaker influenced their listener-intelligibility scores, and (3) the distance of the listener from the speaker did not have a significant effect on listener-intelligibility scores within three to nine-foot limits. The importance of speech-reading training and the use of visual cues is evident where face-to-face voice communication has to be conducted in high intensity noise environment.
