This paper is concerned with the prosodic features of "anger" expressions in Japanese speech. We compared aural impressions of speech with the physical parameters of the prosodic features. One female announcer uttered 4-mora and 6-mora words with four degrees of anger: neutral, displeasure, anger, and fury. Listening tests were conducted using these words as speech samples to quantify aural impressions. Prosodic-feature parameters were speech rate and F0 parameters. Analysis results were as follows: (1) The prosodic-feature parameters that correlate to the rate of coincidence between the listening test result and the speaker's intention were the magnitude of accent command and minimum and maximum fundam ental frequencies, (2) The prosodic-feature parameters that correlate to the rate of identification as a specific degree of emotion were the magnitude of accent command and maximum fundamental frequency, and (3) The coincidence rates for displeasure (35.0%) and anger (23.3%) were low compared with that for fury (70.8%).
