In this paper, we describe a new methodology to develop mixed-initiative spoken dialog systems, which is based on the extensive use of simulations to accelerate the development process. With the help of simulations, a system providing informa- tion about a database of nearly 1000 restaurants in the Boston area has been developed. The simula- tor can produce thousands of unique dialogs which benefit not only dialog development but also pro- vide data to train the speech recognizer and under- standing components, in preparation for real user interactions. Also described is a strategy for creat- ing cooperative responses to user queries, incorpo- rating an intelligent language generation capability that produces content-dependent verbal descriptions of listed items.
