语音信号中的元音间隔的百分比（%V）和辅音间隔的标准偏差（deltaC）是两个维度，根据这两个维度，不同节奏类别（例如，重音定时的、音节定时的）的语言似乎在声学水平上是可区分的（Ramus等人，1999年）。在这种情况下，已经发现，特别是Δ C作为语音速率的函数而显著变化（巴里等人，2003和Dellwo &瓦格纳，
2003年）。
本文认为，如果deltaC是由语音速率，它将描述的语音速率，而不是节奏。出于这个原因，将计算变化系数（varcoDeltaC），以便监测跨语音速率的相对deltaC变化。varcoDeltaC的结果支持以下观点：a）根据varcoDeltaC节奏类似乎更好地区分，以及B）某些语言的节奏倾向于作为语速的函数而变化（德语，英语），而其他语言的节奏似乎不受语速变化的影响（法语）。
The percentage of vocalic intervals (%V) and the standard deviation of consonantal intervals (deltaC) in a speech signal are two dimensions according to which languages of different rhythm classes (e.g. stress-timed, syllable-timed) seem to be differentiable on an acoustic level (Ramus et al., 1999). In this context it has been found that especially deltaC varies considerably as a function of speech rate (Barry et al., 2003 and Dellwo & Wagner,
2003).
The present paper argues that if deltaC was determined by speech rate it would describe speech rate rather than rhythm. For this reason a variation coefficient (varcoDeltaC) will be calculated in order to monitor relative deltaC variation across speech rates. Results for varcoDeltaC support the views that a) according to varcoDeltaC rhythm classes seem to be better differentiable and b) some languages tend to vary in rhythm as a function of speech rate (German, English), while the rhythm of other languages seems to be unaffected by changes in speech rate (French).
