Abstract
本研究は,多人数会話における話者交替は,発話終了より以前に,参与者らの発話志向態度(次に話したい,話させたい態度)の表出から予測されていると仮定し,次話者予測モデルを提案する.これまで話者交替は,参与者による選択テクニックで成立すると説明されている.そこで,我々は会話映像を用いて,参与者らが話者交替に先立って,どのような発話志向態度を表出しているかを第三者に評定させ,その評定結果と実際の話者交替結果を調べる.その結果,次話者は参与者が選択に向けて明示的に操作するのではなく,発話志向態度の解釈により予測されている可能性を述べる.
This paper proposes a novel turn-taking model in which participants in conversations estimate next possible speaker based on the 'preceding utterance attitudes' (want to speak/let someone speak) in advance of actual turn-takings and shows that the estimation model contributes to understanding of turn-taking phenomena. In the existing turn-taking rule of multiparty conversation proposed by Sacks explains that turn-takings are performed by using 'current speaker selects next' technique. In this research, first, preceding utterance attitudes are evaluated by three evaluators by observing conversation scenes and evaluated attitudes are compared with actual turn-taking results. From the analysis, we suggest that the next speaker is selected by expressing and estimating attitudes of utterance among participants rather than others' utterances.
