Abstract：The openness, colloquialism and diversity of out-of-domain (OOD) utterances make them difficult to the domain specific spoken dialogue system. This paper tackles this problem by proposing a coprocessor for domain specific dialogue system. Based on the artificial intelligence markup language(AIML), open semantic understanding templates are designed, and understanding template classification is used to address the unmatched OOD utterances. Then the extended finite state machine (EFSM) is adopted to transform the understanding template into answering template and realize the control of the state and information of the dialogue process. The application in mobile phone shopping guide domain shows that the proposed coprocessor can effectively help the Chinese dialogue system to finish the dialogue process and get better user experience.
