Abstract
In this research, we analyzed the dialogue that consisted of an instruction and a response utterance to clarify the relation between cognitive process and timing structure of utterance. The results showed that correlation coefficient between duration of instruction utterance and switching pause had diverse values when fluctuation of instruction utterance duration was too small to be recognized. However, the correlation coefficient between them had positive and high value when fluctuation of instruction utterance was explicitly big. From these results, we discussed that there are two types of utterance structure in human dialogue.
