An Analysis of Individual Differences in the F0 Contour and the Duration of Anger Utterances at Several Degrees

Taking up anger emotion expressed by speech, prosodic features were analyzed in order to find out the relationship between the degree of anger and manifestations on the speech signal in terms of individual differences. As a result of analysis, there were some common features among the speakers, although there were some speaker-dependent features. About the baseline frequency and the magnitude of the first phrase command, common tendencies were found in all speakers. The amplitude of the accent command increases as the emotional degree increases on the whole. Some speakers emphasized accent commands at all positions within a sentence, some emphasized only near the end of a sentence. Speaking rate at the 1st and 4th phrases were faster than those at the 2nd and 3rd phrases for the utterance with emotion, although there was an individual difference in the effect of the emotional degree. It is very interesting that two aspects in prosody, i.e., an F0 contour and a speaking rate, might be complement each other in order to represent a difference of emotional degrees.
