CommU Multi-Robots Conversation

Social conversation robot providing sense of conversation without voice recognition

Due to the difficulties in automatic speech recognitions, a robot is hard to continue a coherent conversation with a user. In this study, we focus on a new approach which is to coordinate multiple robots in a conversation to avoid conversational collapse caused by such recognition failures. Through lab-experiments and field trials, we revealed that pre-scheduled turn-taking behavior between multiple robots makes an interlocutor feel like a conversation is coherent regardless of defective recognition results. We are trying to apply this cooperative use of multiple robots to the information presentation systems in education, therapy and advertisement.
