Fluency is an important part of research on second language learning, but most research on language proficiency typically has not included oral fluency as part of interactions even though natural communication usually occurs in conversations. The present study considered aspects of turn‐taking behavior as part of the construct of fluency and investigated whether these aspects differentially influence perceived fluency ratings of native and nonnative speech. Results from two experiments using acoustically manipulated speech showed that, in native speech, too “eager” answers (interrupting a question with a fast answer) and too “reluctant” answers (answering slowly after a long turn gap) negatively affected fluency ratings. However, in nonnative speech, only too “reluctant” answers led to lower fluency ratings. Thus, we demonstrated that acoustic properties of dialogue are perceived as part of fluency. By adding to the current understanding of dialogue fluency, these lab‐based findings carry implications for language teaching and assessment.

对话中的流利度:母语和非母语语音的轮流感知行为形状

流利度是第二语言学习研究的重要组成部分,但大多数语言熟练度研究通常没有将口语流利度作为互动的一部分,即使自然交流通常发生在对话中也是如此。本研究考虑了轮流行为的各个方面,将其作为流利性构建的一部分,并调查了这些方面是否会差异地影响母语和非母语语音的流利等级。两个使用声学处理语音的实验的结果表明,在母语中,过于“急切”的答案(以快速答案打断问题)和过于“不情愿”的答案(在较长的转弯间隙后缓慢回答)会对流利度等级产生负面影响。但是,在非母语发言中,只有过于“不情愿”的答案才会导致流利程度较低。从而,我们证明了对话的声学特性被视为流利性的一部分。通过增加当前对对话流利性的理解,这些基于实验室的发现对语言教学和评估具有启示意义。
