Many languages exhibit nasal cluster dissimilation, in which an illicit sequence of nasal–stop clusters is modified in some way (e.g. NC1VNC2 → N1VNC2). This article discusses generalisations in the typology of nasal cluster dissimilation, and claims that nasal cluster dissimilation is driven by constraints on contrast distinctiveness: it occurs preferentially in those environments where the first NC is most confusable with a plain nasal consonant. I propose an analysis that appeals to auditory factors, and provide acoustic and perceptual evidence that is consistent with it.

对对比度的限制促使鼻簇异化

许多语言表现出鼻音簇异化，其中以某种方式修改了非法的鼻塞音序列（例如 NC1VNC2→ N1VNC2）。本文讨论了鼻簇异化类型学的概括，并声称鼻簇异化是由对比独特性的限制驱动的：它优先发生在第一个 NC 与普通鼻辅音最容易混淆的那些环境中。我提出了一个吸引听觉因素的分析，并提供与之一致的声学和感知证据。
