This paper describes an early prototype of a telephone based oral dialogue system developed within the ESPRIT SUNDIAL project. Prototypes have been implemented in four languages for two major application areas, flight reservations and enquiries and train timetable enquiries. The paper discusses the overall system architecture adopted and the approaches taken within each of the major modules of the system. Some preliminary results are shown for parts of the system.
