This book constitutes the refereed proceedings of the international Tutorial and Research Workshop on Affective Dialogue Systems, ADS 2004, held in Kloster Irsee, Germany in June 2004.
The 21 revised full papers and 14 revised short papers presented were carefully reviewed and selected for presentation. The papers are organized in topical sections on emotion recognition; affective user modeling; emotional databases, annotation schemes, and tools; affective conversational agents and dialogue systems; synthesis of emotional speech and facial animations; affective tutoring systems; evaluation of affective dialogue systems; and demonstrations.
Human conversational partners are able, at least to a certain extent, to detect the speaker’s or listener’s emotional state and may attempt to respond to it accordingly. When instead one of the interlocutors is a computer a number of questions arise, such as the following: To what extent are dialogue systems able to simulate such behaviors? Can we learn the mechanisms of emotional behaviors from observing and analyzing the behavior of human speakers? How can emotions be automatically recognized from a user’s mimics, gestures and speech? What possibilities does a dialogue system have to express emotions itself? And, very importantly, would emotional system behavior be desirable at all?
Given the state of ongoing research into incorporating emotions in dialogue systems we found it timely to organize a Tutorial and Research Workshop on Affective Dialogue Systems (ADS 2004) at Kloster Irsee in Germany during June 14–16, 2004. After two successful ISCA Tutorial and Research Workshops on Multimodal Dialogue Systems at the same location in 1999 and 2002, we felt that a workshop focusing on the role of affect in dialogue would be a valuable continuation of the workshop series.
