Stop consonant voice onset time (VOT) was examined in a typological survey of over 100 languages. Within broadly defined laryngeal categories (long-lag, short-lag, and lead voicing), VOT means were found to vary extensively. Importantly, the means for members of the same laryngeal series did not vary independently but instead were highly correlated across languages. The strong linear relations identified here cannot be reduced to previously reported ordinal relations, and provide evidence for a uniformity constraint on phonetic realization: within a language, each laryngeal specification must be realized in approximately the same way across stops of different places of articulation.
本文对 100 多种语言进行了类型学调查，研究了塞音的嗓音起始时间（VOT）。在广义的声门类别（长时滞、短时滞和引导发声）中，发现 VOT 均值差异很大。重要的是，同一声门系列成员的均值并非独立变化，而是在不同语言中高度相关。这里确定的强线性关系不能简化为先前报告的顺序关系，为语音实现的一致性约束提供了证据：在一种语言中，每个声门特征必须在不同发音部位的塞音中以大致相同的方式实现。
