An analysis of the frequency, time and dynamics characteristics of the acoustic signal is one of the useful and reliable methods of objective assessment of the psychophysiological state of a pilot. The information conveyed through the nonverbal channel is nonspecific. The pattern of the stressor that causes a change in the pitch can be often identified only tentatively, if there is no additional information. The intensity of the stressor cannot be well correlated with the degree of the pitch change. The voice alters most seriously in response to psychic stressors and factors that affect adversely the normal merchanics of respiration (breathing at increased pressure, acceleration). The voice remains unaltered during an exposure to hypoxia and high ambient temperatures.
