Possibilities and limits of using speech signals in aviation and space psychophysiology.
A number of measurable speech characteristics reflect the emotional state and its influence upon the operators performance. The validity of acoustical and temporal measures of paralinguistic and semantic processes increases with the increase of motional activation. At lower activation levels the informational value of characteristics is mostly affected by linguistic factors as well as by pychological ones, related to social communication in the course of common working activity.
