CobotDS: a spoken dialogue system for chat

We describe CobotDS, a spoken dialogue system providing access to a well-known interact chat server called LambdaMOO. CobotDS provides real-time, two-way, natural language communication between a phone user and the multiple users in the text environment. We describe a number of the challenging design issues we faced, and our use of summarization, social filtering and personalized grammars in tackling them. We report a number of empirical findings from a small user study.
