Abstract A growing body of literature suggests that the world's languages can be classified into three rhythm classes: mora-timed languages, stress-timed languages, and syllable-timed languages. However, scholars cannot agree on which rhythmic measures discriminate rhythm classes most satisfactorily and whether the speech rate factor should be considered. In this study, we analyze speech production by bilingual speakers, and compare their production with that of monolingual speakers and ESL speakers. Our rhythmic metric measure results show that when speech rate is taken into consideration, a combination of the two metric measures for vowels, Varco∆V and vocalic nPVI, is most reliable in discriminating different rhythm classes, while consonants do not seem effective, whether the speech rate factor is included or not.

莫拉定时、重音定时和音节定时节奏课程：双语者在英语演讲中的线索

摘要 越来越多的文献表明，世界上的语言可以分为三个节奏类别：节奏型语言、重音型语言和音节型语言。然而，对于哪种节奏措施最能令人满意地区分节奏类别以及是否应考虑语速因素，学者们无法达成一致意见。在这项研究中，我们分析了双语者的演讲产出，并将他们的产出与单语者和 ESL 演讲者的产出进行了比较。我们的节奏度量测量结果表明，当考虑到语速时，元音的两种度量度量 VarcoΔV 和声乐 nPVI 的组合在区分不同的节奏类别时最可靠，而辅音似乎并不有效，无论是包括或不包括语速因素。
