This paper describes the integration of the main components of a man-machine dialogue system for the Italian language, which allows information services to be accessed through the telephone line. The components are: 1) a large vocabulary speaker-independent continuous speech recogniser (AFE), 2) a natural language understanding stage (LP), 3) an intelligent dialogue manager (DM) and 4) a message generator (MG), including a high quality text-to-speech synthesiser. A prototype of an intermediate development state for E-mail access was presented in [lj. In the current implementation, a user can access a train information service through a PBX telephone line. A general overview of the system architecture will be given together with an evaluation of the real-time demonstrator performance through experienced and naive users.
