Strident

粗糙[音]

One of the source features of sound set up by Chomsky and Halle in their distinctive feature theory of phonology, to handle variations in the sibilance of a sound. Strident sounds are defined articulatorily and acoustically as those sounds produced by a relatively complex stricture, and marked by relatively high frequency and intensity, as in [f], [s] and [ʃ]. The opposite term is Jakobson and Halle’s approach in mellow; in Chomsky and Halle’s later system it is non-strident: these are sounds produced by a less complex stricture, and marked by noise of relatively low frequency and intensity, such as plosives and nasals. 

乔姆斯基和哈勒在其音系学的区别特征理论中确立的声源特征之一，用来描写语音咝音性的变化，粗糙音从发音和声学两方面定义为：发音时制流比较复杂，有频率和强度较高的特点，例如[f]，[s]，[ʃ]。对立的术语在雅克布逊和哈勒的模型中是圆润[音]，在乔姆斯基和哈勒后期的系统中是非粗糙[音]；这些音发音时制流不太复杂，有噪音的频率和强度较低的特点，如破裂音和鼻音。
