Previous research has provided ample evidence for the processing advantage of formulaic sequences, leading researchers and teachers to argue for its facilitation of speech fluency. However, few studies have examined how the processing of formulaic sequences interacts with speaker proficiency and task difficulty; even fewer studies have investigated how formulaic sequences facilitate different dimensions of speech fluency. To address these gaps, this study examined the impact of formulaic sequences on speech fluency for both first and second language speakers (N = 269) across proficiency levels on elicited imitation tasks. Participants' speech fluency was measured on both rate and pausing features. Results from linear mixed‐effects models reveal that formulaic sequences had a significant effect on the reduction of pauses, but not on speech rate. The effect on pausing was stronger in the processing of long sentences and on intermediate second language speakers. These results suggest that formulaic sequences have differential impacts on the rate and pausing dimensions of speech fluency, and the impacts are further conditioned by speaker proficiency and task difficulty. Findings of this study have both theoretical and pedagogical implications regarding the acquisition of formulaic sequences and the development of speech fluency.

在拟议的模仿任务中解开公式序列与语音流利度之间的关系:熟练度,句子长度和流利度维度

先前的研究为公式序列的处理优势提供了充足的证据,导致研究人员和教师争辩说它有助于语音流利。但是,很少有研究检查公式化序列的处理如何与说话者的熟练程度和任务难度相互影响。很少有研究调查公式化序列如何促进语音流利性的不同维度。为了解决这些差距,本研究研究了母语和第二语言使用者的常规序列对语音流利性的影响(N= 269)的水平,以完成模仿任务。参与者的语音流利度是根据速率和暂停功能进行衡量的。线性混合效应模型的结果表明,公式化序列对暂停的减少有显着影响,但对语速却没有影响。在长句处理和中级第二语言说话者中,对暂停的影响更强。这些结果表明,公式化序列对语音流利度的速率和暂停维度有不同的影响,并且这些影响还取决于说话者的熟练程度和任务难度。这项研究的发现对公式序列的获取和语音流利度的发展都具有理论和教学意义。
