In this paper we present our recent activities in developing systems for vocal access to a database information retrieval system, for three applications in a travel domain: L'Atis, Mask and RailTel. The aim of this work is to use spoken language to provide a user-friendly interface with the computer. The spoken language system integrates a speech recognizer (based on HMM with statistical language models), a natural language understanding component (based on a caseframe semantic analyzer and including a dialog manager) and an information retrieval and response generation component. We present the development status of prototype spoken language systems for L'Atis and Mask being used for data collection.
