本研究旨在揭示日语自然会话中与下一说话人选择相关的韵律特征。社会学会话分析领域的话轮转换系统是会话中说话人转换的系统基础。在以前的研究中，我们证明了日语话语的韵律与系统的一个组成部分，即话轮结构成分有关。然而，目前还不清楚是否韵律也相关的另一个组成部分，即轮分配组件。在本文中，而专注于下一个说话人选择的话轮分配技术之一，我们研究的韵律特征和下一个说话人选择的话语类型之间的关系。结果表明，在话语中倒数第二个和最后一个重音短语之间的F0的差异是不同的，无论当前话语选择下一个说话人。此外，当前说话人是否在当前话语中进行自我选择，在最后重音短语处的功率和莫拉持续时间不同。这表明韵律特征是当前话语中选择下一个说话人的线索。
This study aims to reveal prosodic features related to next speaker selection in spontaneous Japanese conversation. A turn-taking system in the field of conversation analysis in sociology was proposed as a systematic basis of speaker-change for conversation. In a previous study, we demonstrated that the prosody of Japanese utterance is relevant to one component of the system, namely, a turn-constructional component. However, it is unclear whether the prosody is also relevant to another component, that is, a turn-allocation component. In this paper, while focusing on next speaker selection as one of the turn-allocation techniques, we investigated relationships between the prosodic features and types of next speaker selection in utterances. The results showed that the difference of the F0s between the penultimate and the final accent phrase in utterance differs whether the current utterance selects the next speaker. Also, the power and the mora duration at the final accent phrase differ whether the current speaker does self-selection in the current utterance. These suggest that the prosodic features are clues for selecting the next speaker in the current utterance.
