A Multilingual Spoken Dialog System

This paper will briefly introduce MSDSKIT-1 (Multilingual Spoken Dialogue System Version 1.0 developed by Kyoto Institute of Technology) which integrates Japanese and Chinese now. It is a promotion vision of the SDSKIT-3 (Spoken Dialogue System in Japanese). This system can provide services such as sight-seeing introduction, traffic guidance, hotel reservation. A user can also plan his itinerary under the conduction of the system. We regard a spoken dialogue system as an integrated system with a language-dependent speech interface and a language-independent dialogue controller. We must carefully consider the linguistic characteristics of the particular language for the language-dependent interface during designing a multilingual spoken dialogue system, for example, the syntactical structural features for the language parser. In order to promote SDSKIT-3 into a multilingual system (called as MSDSKIT-1), a great effort has been taken. This paper will present such effort on two aspects: (1) Chinese speech recognizer (2) Chinese language parser.
