| Outline of Final Research Achievements |
In face-to-face conversations, the prosody of speech reflects some kind of interpersonal information, and is closely related to speaking style adapted to a situation. In this research, we conduct a dialogue experiment that controlled the conditions such as appearance and way of speaking using humanoid robot. In order to investigate if and how speaking styles change depending on the dialogue partner, we conducted an experiment where subjects hold conversations with two different humanoid robots, one elder and the other coeval with the subjects. We extracted prosodic features from the speech data of the subjects and analyzed intra-individual variability. The occurrence of laughter events was also analyzed. The analysis results showed that speech rate, fundamental frequency and the number of laughter events are significantly different depending on the dialogue partner.
