This paper describes a multimodal dialogue system under development in our lab which has been designed to assist students and professors in some of their daily activities within the Faculty of a University. The system combines features of multimodal dialogue systems and Ambient Intelligence. The paper focuses on the system's architecture, which is based on XHTML+Voice. It explains the speech- and GUI-based interfaces, and discusses the connection of both. Then it explains the system usage, shows a sample interaction and discusses the identification and localization of users within the Faculty. Finally, it presents the conclusions and outlines possibilities for future work.
