Heterogeneous Multi-Robot Dialogues for Search Tasks

Dialogue agents are often designed with the tacit assumption that at any one time, there is but one agent and one human, and that their communication channel is exclusive. We are interested in examining situations in which multiple heterogeneous dialogue agents need to interact with a human interlocutor, and where the communication channel becomes necessarily shared. To this end we have constructed a multi-agent dialogue test-bed on which to study dialogue coordination issues in multirobot scenarios.
