発話タグの統計的特性を考慮した対話における適切な発話タイミング

抄録

In this research, to determine proper utterance timing in the dialogue system, we have analyzed the impression of the timing with regard to the four dialogue contents. In this experiment, the dialogue contents were composed of four pairs of sentences that were selected based on the statistical results of tagged dialogue corpus. Five utterance timings including overlaps were prepared for the experiment and were evaluated by the subjects by pairwise comparison. The results suggested that the utterance timing from 400 to 600ms gave better impressions in usual conversations.
