Analysis of User Reactions to Turn-Taking Failures in Spoken Dialogue Systems

This paper presents the results of an analysis of user reactions towards system failures in turn-taking in human-computer dialogues.When a system utterance and a user utterance start with a small time difference, the user may stop his/her utterance.In addition, when the user utterance ends soon after the overlap starts, the possibility of the utterance being discontinued is high.Based on this analysis, it is suggested that the degradation in speech recognition performance can be predicted using utterance overlapping information.
