Dialogue system

A dialogue system, by the use of artificial speech, addresses the user, but also recognises and responds to the speech of the user. A dialogue system therefore comprises of at least a text-to-speech or concept-to-speech module, and a speech recognition module. These dialogue systems are being used for (telephone) information systems on e.g. rates of exchange on the stock market, train schedules, or for booking of plane or train tickets.
