A study on utterance adjustment strategies of Talking-Ally that utilizes speech disuencies

Abstract

Disuencies in spontaneous speech is often regarded as speaker's speech error, and it is often explained by attributing it to the internal mechanism of the speaker. On the other hand, it can also be regarded that disuencies were created as a result of the interaction between the speaker and the hearer. From this point of view, an utterance generation system “Talking-Ally” has been constructed. In this study, the objective is to explore the factors that create disuencies by a constructive approach. In particular, it focuses on the conversation adjustment function related to maintaining the conversational situation when the hearer's eye-gaze deviates from the conversation. First, we constructed a model to adjust the utterance strategies while adapting it to the hearer, then conducted an interaction experiment by using this model. And we discussed how disuencies of utterances can work.
