The issue addressed in this study is effects of speakers’ fast speech rate (FSR) and strong accent (StrA) on simultaneous interpretation (SI) quality. Although it is perceived that FSR and StrA negatively affect overall SI quality, such effects have been mostly derived from small-sample quantitative studies and have not been consistently borne out by empirical evidence. The present mixed-methods study therefore draws upon a sample of 32 professional interpreters to shed both quantitative and qualitative insights into the issue. In particular, a parallel mixed design was used in Phase I of the study to explore the effects of FSR and StrA on three measures of SI performance (i.e., fidelity, fluency and expression), followed by Phase II where data quantitizing was performed to verify an emerging finding from Phase I. Overall, FSR produced differential effects on the three measures, while StrA exerted a consistent detrimental effect across the measures.

研究语速和口音对同声传译的影响：混合方法

本研究中解决的问题是说话者的快速语速 (FSR) 和重口音 (StrA) 对同声传译 (SI) 质量的影响。尽管人们认为 FSR 和 StrA 对整体 SI 质量有负面影响，但这种影响主要来自小样本定量研究，并没有得到经验证据的一致证实。因此，目前的混合方法研究利用了 32 名专业口译员的样本，以对这个问题进行定量和定性的分析。特别是，在研究的第一阶段使用平行混合设计来探索 FSR 和 StrA 对三个 SI 性能指标（即保真度、流畅度和表达）的影响，然后是第二阶段，其中进行数据量化以验证第一阶段的一个新发现。总的来说，
