A Mandarin spoken dialogue system with limited portability

In the new generation human-computer interaction technology, spoken dialog system based on content is the key issue. This paper describes the status of our spoken dialogue system for tour information retrieval - GUIDE - whose lexicon consists of 2000 words and WER is 5.7%. Different from ATIS application, tour information is wider and more relative. So we develop an object-oriented knowledge base including database and deducing rules. We also develop a modular architecture of GUIDE: by doing so, we have successfully and easily adapted GUIDE to a new similar application.
