| Abstract(in English) | This paper describes the discrimination among emotion expressions contained in speech. At first, we investigated an influence of these emotion expressions (anger, pleasure and sadness) on performance of continuous speech recognition system using 1040 sentences uttered by 13 speakers. We found that those three emotions gave 10% to 20% down on the performance. Next, we investigated effective parameters for discrimination among emotions. Based on canonical discriminant analysis, the following parameter are effective for all speakers : maximum fundamental frequency, maximum power and variation range of fundamental frequency. Discriminant rates for all speakers decrease in order of anger (61.4%), pleasure (53.1%) and sadness (45.8%). On the other hand, we also found that contribution rate of these parameters is different dependent on speaker characteristics. |
