A description is given of a conversational mode speech understanding system which enables its user to make airline reservations and obtain timetable information through a spoken dialogue. The system is structured as a three-level hierarchy consisting of an acoustic work recognizer, a syntax analyzer and a semantic processor. The semantic level controls an audio response system making two-way speech communication possible. The system is highly robust and operates on-line in a few times real time on a laboratory minicomputer. The speech communication channel is a standard telephone set connected to the computer by an ordinary dialed-up line.
