Abstract : The purpose of the investigation was to determine the relation of syllable duration and intensity to speech intelligibility. Three conditions of R/T communication were studied: (a) subjects talking over R/T circuits in quiet (no aircraft noise in headset) prior to voice communication instruction; (b) subjects talking over R/T circuits with aircraft noise in headset prior to training; and (c) subjects talking over R/T circuits with noise after two hours of voice communication instruction. The relationships of syllable duration and intensity to speech intelligibility in these three situations were studied. (Author)
