DialogXpert plans goal-directed dialogue by using a frozen large language model to propose actions and a learned value model to choose among them, with inferred user emotions included in its state. In LLM-simulated evaluations across negotiation, emotional support, and tutoring, it reports 2.32 average turns and 0.9746 success on CraigslistBargain. Real-user performance is not established.
