| Abstract(in English) | This paper describes a method for estimating the internal state of the user of a spoken dialog system before his input utterance. In the practical use of dialogue-based system, the user often perplexed with the prompt. An ordinary system provides more detailed information to the user taking time to input, but these helps are meddlesome for the user considering the answer to the prompt. To make appropriate response, the spoken dialogue system have to be able to consider the user's internal state before user's input. The conventional researches on user modeling have focused on the linguistic information of the utterance. One problem of these approaches is that it cannot estimate the user's states until the end of the user's first utterance. Therefor, our study focused on the user's non-verbal output such as fillers, silence or head-moving until the occurrence of user's input utterance. This paper describes the method of the user modeling by HMM. We conducted the examination discrimination, and obtained the accuracy of 79.6%. |
