A Spoken Dialogue System for Electronic Program Guide Information Access

In this paper, we present POSTECH Spoken Dialogue System for Electronic Program Guide Information Access (POSSDS-EPG). POSSDS-EPG consists of automatic speech recognizer, spoken language understanding, dialogue manager, system utterance generator, text-to-speech synthesizer, and EPG database manager. Each module is designed and implemented to make an effective and practical spoken dialogue system. In particular, in order to reflect the up-to-date EPG information which is updated frequently and periodically, we applied a web-mining technology to the EPG database manager, which builds the content database based on automatically extracted information from popular EPG websites. The automatically generated content database is used by other modules in the system for building their own resources. Evaluations show that our system performs EPG access task in high performance and can be managed with low cost.
