ISCA Tutorial and Research Workshop International Speech Communication Association Error Handling in Spoken Dialogue Systems Preliminary Call for Participation Location: Hotel Roc et Neige http://www. cm.be/images/intersoc/Chateau/chateaug.htm Chateau-d'Oex-Vaud, Switzerland http://www.skis witzerland.com/chateau/chateau.htm August 28-31, 2003 Workshop website: http://www.speech.kth.se/error/ Webmaster: Gabriel Skantze Email contact: errorworkshop_(on)_speech.kth.se Supported by: CLIF (Computational Linguistics in Flanders) SIGDIAL Aims: Spoken dialogue systems in real applications as well as research have attracted increased attention in recent years. With the limitations of current speech technologies, both for recognition and understanding and for speech generation, this interest in `real' systems has led to an increased awareness in the problems raised by system errors, especially in recognizing user input, and the consequent confusion they may lead to for both users and the system itself over the dialogue. The need to devise better strategies for detecting problems in human-machine dialogues and then dealing with them gracefully has become paramount for spoken dialogue systems. This workshop will consider all aspects of how systems can detect and recover from problems in spoken dialogue systems. We will address questions such as: What can we learn from errors in human-human and wizard-of-Oz systems that will help us to handle error in human-machine dialogue systems? How do systems detect when a dialogue is `going wrong'? How do they define such conditions? What factors are the key contributors to and indicators of `bad' dialogues? How do systems identify their own errors? What are the most important causes of such errors, from the user side (e.g. non-native accent, hyperarticulated speaking style, gender, age) and from the system side (e.g. inappropriate prompts)? How difficult is it to determine the causes of particular error? How can we predict which dialogues will be successful? How should we define `success'? What features can best predict it? What mechanisms can be devised to allow systems to recover from error gracefully? Can we devise adaptive strategies to identify patterns of error and respond accordingly? What sorts of behavior do users exhibit when faced with system errors? Can these be taken into account in error handling? What measures (better prompts, anticipation of likely error, better help information) can be taken to minimize possible errors? Papers are invited on innovations in ways that systems can detect their own errors (e.g. through features such as ASR confidence scores); on methods for evaluating spoken dialogue systems that include system errors and error recovery as a major component; on strategies for determining on-line when dialogues are `going wrong'; on mechanisms for recovering once errors are detected; on laboratory and corpus-based studies of human behavior relevant to human-machine problem detection/recovery; on methods for minimizing dialogue problems (e.g. by varying dialogue strategy, system prompts). Position papers are also invited for a special session on aspects of error handling are most in need of additional attention and to propose research approaches in such areas.
