会話支援するロボットの支援タイミングの評価

抄録

We are studying a robot that provides a topic of discussion for carrying on lively and smooth human-to-human communication. It is necessary to confirm the importance of controlling the speech timing in consideration of the smoothness of the conversation. We compared three type of robots that talk on different timing, such as (1) speaking without considering the conversation atmosphere, (2) speaking when the conversation is stagnating, (3) talking when the conversation is excited. We analyzed how change the conversation atmosphere after providing topic, and we confirmed the impression that the talker feels to the robot. As a result, the impression on the robot was good when talking to excited conversation, but the situation of the conversation after speaking was getting worse. On the other hand, when talking when the conversation is stagnant, the conversational situation after speaking tends to improve.
