| Research Abstract |
Designing a spoken dialogue interface involves an appropriate handling of recognition errors, which often caused by background noise or indistinct voice uttered by users, and has great impact on the usability of such interface system. This study has developed the methods for estimating user's recognition accuracy by his/her utterance, and also investigated the method to apply the recognition accuracy estimate, which depends on a dialogue state, for optimal selection of responses to the user. Evaluation experiments showed the effectiveness of the proposed methods.
