我们研究韵律和语境因素表征的反向通道功能的单个肯定词。数据来自标准美式英语的发言者之间的合作任务为导向的对话。尽管词汇变异性很高，但反向通道在韵律上定义得很好：它们比表达其他语用功能的肯定词具有更高的音高和强度以及更大的音高斜率。此外，我们确定短语最后上升音高作为一个显着的触发backchanneling。
We examine prosodic and contextual factors characterizing the backchannel function of single affirmative words. Data is drawn from collaborative task-oriented dialogues between speakers of Standard American English. Despite high lexical variability, backchannels are prosodically well defined: they have higher pitch and intensity and greater pitch slope than affirmative words expressing other pragmatic functions. Additionally, we identify phrase-final rising pitch as a salient trigger for backchanneling.
