In the demonstration, a conversation robot that facilitates four-participant conversation and answers questions from other participants is shown. The participants consist of the robot and three persons, one host and two guests. The topic of conversation is introduction of the robot itself. The demonstration is realized from three key functions: (1) answering the question from the participant, (2) facilitating utterances of a participant who has less turns relatively than others, and (3) managing the addressee of the answer especially to the question which the host asks on behalf of the guests.
