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.
