Abstract
Research was conducted to determine if alterations in the acoustical
characteristics of voice occur after moderate cumulative sleep deprivation. Eight
subjects participated in the study. Sleep deprivation was obtained by prescribing four
nights of reduced sleep (6 hrs instead of 8). Speech data were obtained with
sociometric badges, cognitive and subjective fatigue data were also collected. Speech
volume and pitch were found to be significantly different when subjects were sleep
deprived. Secondary circadian effects were not observed. The results support the
proposition that speech can be used to measure the fatigue state of individuals.
