document: An information state-based dialogue manager for making voice web smarter In this paper we propose the integration of intelligent components technologies ( natural language and discourse management ) in voice web interfaces to make them smarter . We describe how we have integrated reusable components of dialogue management and language processing in a multilingual voice system to improve its friendliness and portability . The dialogue management component deals with complex dialogue phenomena , such as user-initiative dialogues , and follows the information state-based theory . The resulting dialogue system supports friendly communication ( through the telephone and the web ) in several languages : English , Spanish , Catalan and Italian . The dialogue system has been adapted to guide the users to access online public administration services .
