The Design of a Multi-Domain Mandarin Chinese Spoken Dialogue System

Yi-Chung Lin, Tung-Hui Chiang, Heui-Ming Wang, Chung-Ming Peng, Chao-Huang Chang


In some dialogue systems, the design of dialogue strategy is bound tightly to the domain by straightforwardly hard-coding the response actions into the system. Such a paradigm is quite easy to build up a prototype system, but makes it difficult to port the system across different domains. This paper presents a domain-transparent design of dialogue management to increase system portability. The basic idea of this framework is to extract the domain-dependent factors to form an external domain knowledge database, leaving the dialogue management component independent of the tasks. Based on the proposed framework, porting to another domain needs only to replace the domain knowledge database without changing the dialogue management module. This paper also proposed a task description table interface enabling system developers to design the dialogue strategy flexibly. With this approach, the effort of porting a spoken dialogue system across different domains can be relieved.
