Jennifer Lai is a Senior Designer who has been working in field of Speech Recognition at the IBM T.J. Watson Research Center for 12 years. During the first 6 years she worked on the IBM Speech Recognition engine, creating language models and tools to facilitate model creation, while for the last 6 years she has directed her attention to developing speech applications for users. Jennifer specializes in requirements gathering and analysis, interaction design, and usability testing for speech systems including the IBM product MedSpeak for Radiology. As the lead for User Centered Design, Jennifer has focused more closely the past few years on managing relationships with the user/client development partners. She has published numerous papers on the use of speech in multi-modal systems, the comprehensibility of text-to-speech, the development of statistical language models and has multiple patents in Natural Language Translation and Speech Interfaces. She has taught a full day tutorial on the design of speech interfaces at CHI every year for the past four years, has presented papers at CHI'97, 2000 and 2001, and has participated in several CHI workshops. She has also led both workshops and focus groups as part her work at IBM.

Nils Dahlbäck is Assistant Professor in Cognitive Science at the Natural Language Processing Laboratory at the Computer and Information Science Department, Linköping University, Sweden. He earned Bachelor Degrees in Psychology (1973) and in Speech Therapy (1997) from Lund University, and his Ph.D. in Communication Studies from Linköping University (1992). His current research interests are: dialogue managers for natural language and multi-modal interaction; hypermedia navigation, especially the influence of individual differences in cognitive and cultural factors; the effects of use of speech interactive technology for non-native language speakers. He has also worked on developing iterative methods for the development of Natural Language interfaces, and especially the use of Wizard of Oz-techniques for this, and on dimensions for describing NL-dialogue systems. He was co-organizer of the CHI 2000 workshop on natural language interfaces, and the CHI 2001 SIG on Natural Language, as well as other workshops on NL-dialogue and multi-modal interaction. He has also participated in a number of CHI workshops previously.

Arne Jönsson is Associate Professor in Computer Science, Department of Computer and Information Science, Linköping University, Sweden. Ph. D, Computer Science (1993). Tech lic, Computer Systems (1984). BA in Education Psychology (1984).  MSc in Computer Technology, (1980).  He has been working with research on natural language interfaces, especially dialogue managers and empirical studies of human computer interaction for almost twenty years. He has organized various scientific workshops on Dialogue Systems, most recently two IJCAI-workshops on "Knowledge and Reasoning in Practical Dialogue Systems". He is project leader for research projects on multimodal interaction, dialogue models and development of Swedish dialogue systems. He has published a number of papers on dialogue systems, methods for empirical investigations and methods for development of dialogue systems.
