Use of the invariant method of speech analysis to discern the emotional state of announcers.
An improved method of discerning emotional colouring of speech on the frequency of main tone and average number of intersections at zero level within the range of first formant frequencies is described. Vowels from words pronounced by announcers in different emotional states served as material for experiments. The method elaborated in the experiments with actors and drama school undergraduates was then tested in natural conditions on amateur parachute jumpers.
