Intimacy Estimation of the Characters in Drama Scenario

Abstract

Recently, a portable digital device equipped with voice guidance has been widely used, increasing the demand for the usability-conscious dialogue system. One of the problems with the existing dialogue system is its immature application to non-task-oriented dialogue. Non-task-oriented dialogue requires some scheme that enables smooth and flexible conversations with a user. For example, it would be possible to provide topics related to a person who is familiar with a user or avoid providing topics related to a person who is not a good friend with the user, by considering relationship with others in real life of the user.

In this paper, we focus on the dialogue made by the two characters in a drama scenario, and tried to express their relationship with a scale of “intimacy degree.” There will be such various elements related to the intimacy degree as the frequency of response to the utterance and the attitude of a speaker during the dialogue. We focus on the emotional state of the speaker during the utterance and try to realize an intimacy estimation with high accuracy. As the evaluation result, we achieved high accuracy in intimacy estimation than the existing method based on speech role.
