使用英语、德语、希腊语、意大利语、韩语和西班牙语测试了节律度量Delta C、%V、PVIs和Varcos的性能，据说这些度量用于量化节律类别区分。每种语言的八名参与者使用三种启发方法，自发演讲，故事阅读和阅读一组句子分为“不受控制”的句子，从每种语言的原始作品，句子设计，以最大限度地提高或最小化音节结构的复杂性（“重音定时”和“音节定时”集分别）。基于汇总数据的节律分类在各个指标之间不一致，而分数的跨语言差异通常在统计学上不显著，即使是英语和西班牙语等原型语言之间的比较。语音表现出大量的说话人之间的变化，并证明非常敏感的启发方法和音节的复杂性，使大小的影响是大的，往往与语言。这些结果表明，任何跨语言的差异所捕获的指标是不强大的，度量分数范围内的语言，很容易受到各种方法的决定，使跨语言的比较和节奏分类的基础上，度量不安全的最好的。(c)2012爱思唯尔有限公司保留所有权利。
The performance of the rhythm metrics Delta C, %V, PVIs and Varcos, said to quantify rhythm class distinctions, was tested using English, German, Greek, Italian, Korean and Spanish. Eight participants per language produced speech using three elicitation methods, spontaneous speech, story reading and reading a set of sentences divided into "uncontrolled" sentences from original works of each language, and sentences devised to maximize or minimize syllable structure complexity ("stress-timed" and "syllable-timed" sets respectively). Rhythm classifications based on pooled data were inconsistent across metrics, while cross-linguistic differences in scores were often statistically non-significant even for comparisons between prototypical languages like English and Spanish. Metrics showed substantial inter-speaker variation and proved very sensitive to elicitation method and syllable complexity, so that the size of both effects was large and often comparable to that of language. These results suggest that any cross-linguistic differences captured by metrics are not robust; metric scores range substantially within a language and are readily affected by a variety of methodological decisions, making cross-linguistic comparisons and rhythmic classifications based on metrics unsafe at best.
