| Abstract | Almost all current spoken dialog systems have treated dialog that one user talks with one agent. In this paper, to achieve the multi-party conversation (polylogue, many users/agents participate conversation), the number of system agents is increased. Three person's conversation system that treats two agents was developed. This system is extended from the spoken dialog system of two people's conversations that we have developed so far. The response timing to the user and respond type are controlled by using a decision tree. The system also reacts robustly to the user's disfluencies. The dialog tasks is ``Which do you prefer, Japanese noodle (udon) or Chinese noodle (ramen) ?''. We compared the three person's dialog system to the two person's system. According to the results of the experiments, the three person dialog system performed better in terms of lively conversation, and the user can talk to the agents more like chatting. |
