This paper describes certain findings of intonation and intensity study of emotive speech with the minimal use of
signal processing algorithms. This study was based on six basic emotions and the neutral, elicited from 1660 English
utterances obtained from the speech recordings of six Indian women. The correctness of the emotional content was
verified through perceptual listening tests. Marked similarity was noted among pitch contours of like-worded,
positive valence emotions, though no such similarity was observed among the four negative valence emotional
expressions. The intensity patterns were also studied. The results of the study were validated using arbitrary
television recordings for four emotions. The findings are useful to technical researchers, social psychologists and to
the common man interested in the dynamics of vocal expression of emotions |
