In this study, we investigate syntactic and prosodic features of the speaker's speech at points where turn-taking and backchannels occur, on the basis of our analysis of Japanese spontaneous dialogs. Specifically, we focus on features such as part of speech, duration, F0 contour pattern, relative height of the peak F0, energy trajectory pattern, and relative height of the peak energy at the final part of speech segments. We examine, first, the relationship between turn-taking/backchannels and each feature of speech segments independently, showing that the features examined in this study are all related to turn-taking or backchannels and that the way they correlate is fairly consistent with previous studies. Next, we explore the inter-relationship among the features with respect to turn-taking and backchannels. We show that in both turn-taking and backchannels, (1) some instances of syntactic features make extremely strong contributions, and (2) in general, syntax has a stronger contribution than any individual prosodic feature, although the whole prosody contributes as strongly as, or even more strongly than, syntax. We also discuss some implications of our results, comparing them with previous models that have mentioned roles of syntax and prosody in turn-taking and backchannels.
在本研究中，我们基于对日语自发对话的分析，调查了在话轮转换和反馈发生点处说话者言语的句法和韵律特征。具体而言，我们关注的特征包括词性、时长、基频轮廓模式、基频峰值的相对高度、能量轨迹模式以及言语片段结尾处能量峰值的相对高度。我们首先分别考察话轮转换/反馈与言语片段各特征之间的关系，结果表明本研究中所考察的特征均与话轮转换或反馈相关，且它们的关联方式与先前研究相当一致。接下来，我们探讨这些特征在话轮转换和反馈方面的相互关系。我们发现，在话轮转换和反馈中，（1）某些句法特征的实例贡献极大，（2）总体而言，句法的贡献比任何单个韵律特征都更强，尽管整体韵律的贡献与句法相当，甚至更强。我们还讨论了研究结果的一些启示，并将其与先前提及句法和韵律在话轮转换和反馈中作用的模型进行了比较。
