We present a dialogue system for a conversational robot, Erica. Our goal is for Erica to engage in more human-like conversation, rather than being a simple question-answering robot. Our dialogue manager integrates question-answering with a statement response component which generates dialogue by asking about focused words detected in the user's utterance, and a proactive initiator which generates dialogue based on events detected by Erica. We evaluate the statement response component and find that it produces coherent responses to a majority of user utterances taken from a human-machine dialogue corpus. An initial study with real users also shows that it reduces the number of fallback utterances by half. Our system is beneficial for producing mixed-initiative conversation.
