With a goal of contributing to multiparty conversation management, this paper proposes a mechanism for estimating conversational dominance in group interaction. Based on our corpus analysis, we have already established a regression model for dominance estimation using speech and gaze information. In this study, we implement the model as a dominance estimation mechanism, and propose an idea of utilizing the mechanism in moderating multiparty conversations between a conversational robot and three human users. The system decides whom the system should talk to based on the dominance level of each user.
