Abstract

Spoken conversational agents have been proposed to enable a more natural and intuitive interaction with the environment and human-computer interfaces. In this paper, we propose a framework to model the user's emotional state during the dialog and adapt the dialog model dynamically, thus developing more efficient, adapted, and usable conversational agents. We have evaluated our proposal developing a user-adapted agent that facilitates touristic information, and provide a detailed discussion of the positive influence of our proposal in the success of the interaction, the information and services provided, as well as the perceived quality.
