Abstract
This paper analyzes turn-taking structure in multiparty conversation based on the attitudes toward participant role expressed by nonverbal expressions. In previous studies turn-taking events have been mainly analyzed focusing on physical modalities such as utterances and gaze-directions. Unlike those studies we focus on expressions of internal statuses or attitudes toward participant roles (want to be a speaker / want to be a hearer) expressed by each participant at turn-takings. First, participant attitudes are subjectively evaluated by third party evaluators, then, are analyzed quantitatively and qualitatively. The results shows that participant attitudes such as “want to be a speaker” and “want to be a hearer” act as important cues for choosing next speaker and hearer. It suggests that the attitudes contribute to smooth turn-takings and cooperative conversations.
