| Abstract(in English) | One of the old but unsolved issues in designing mixed-initiative spoken dialogue systems is how to decide the timing of system utterances. This paper addresses the issue restricting the target domain to information-seeking dialogues. We first claim that it is critically important for a system to decide when it should takes the dialogue initiative, and define the notion of information-requesting utterance segments (IRUSs), which gives useful clues for turn/initiative taking. We then report the present results of our experiments in which we took a machine learning-based approach achieving 81.1% accuracy in segmenting user utterances into IRUSs. We also examined how speech recognition errors influenced the performance of our model, finding that it worked tolerantly to at most 30% word recognition errors. |
