Investigation was conducted on how prosodic features of emotional speech changed depending on emotion levels. The analysis results on fundamental frequency (F0) contours and speech rates implied that humans have several ways to express emotions and use them rather randomly. Investigation was also conducted on what acoustic features were important to express emotions. Perceptual experiments using synthetic speech with copied acoustic features of target speech indicated importance of the segmental features other than the prosodic features. Especially, a high importance was observed in the case of happiness.
