We aim to construct a spoken dialogue system for multiple in-vehicle information system. Conventional studies focused on discrimination of the system request and chat. However, it is difficult to advance dialogues smoothly when the system is not able to accept an user utterance in spite of the system request. In this study, we propose a method to discriminate out of a candidate, a candidate and a chat because we aim to perform different dialogue controls for out of a candidate, a candidate and a chat. This method discriminates utterances using matched rate of recognition results by N-gram and prediction sentences and keywords expressed a domain or a function based on a decision tree. As a result of experiments, the proposed method was able to improve 17% with distinction accuracy in comparison with conventional method based on a likelihood ratio. |
