This paper describes a dialog system allowing a "naive" user to retrieve information from a knowledge base about historical facts, using natural, spontaneous questions in French.
Keyboard input, continuous speech input (through connected word recognition) and isolated word input are provided, as three separate modes. The system is implemented on a VECSYS Datavox speech recognizer, and a PC, programmed in Prolog and C.
Careful assessment sessions were conducted, mainly for continuous speech input. Observations of speakers behaviour when recognition errors occur provide guidelines for implementing better dialog systems in the future.
