Collection of responsive utterances to show attentive hearing attitude to speakers

摘要

One of the stressors for users who have a dialogue with a robot is a doubt about whether or not the robot can comprehend user's utterances. To solve this problem, it is effective for a robot to actively show the attitude of attentive hearing for user's utterances. This paper describes collection of responsive utterances to show the attitude of attentive hearing for the purpose of actualizing conversation robots with attitudes of attentive hearing. In the data collection, we made a worker respond to utterances in Japanese elders' narrative corpus so that the responses become appropriate as a role of a listener. As the result, we collected 4,885 responsive utterances uttered for narratives of 9 elders.
