A dialog system for the DIHANA project

In this paper, we present a dialog system developed in the DIHANA project. This system consists of seven modules: an automatic speech recognizer, a language understanding module, a dialog manager, a database query manager, a natural language answer generator, a text-to-speech converter and, nally , a central communication manager. For the implementation of the system, we built an architecture based on the client-server paradigm, where the central communication manager works as the client and the other modules work as servers.
