Sonorant

响音

One of the major class features of sound set up by Chomsky and Halle in their distinctive feature theory of phonology, to handle variations in manner of articulation. Sonorant sounds are defined articulatorily, as those produced with a relatively free airflow, and a vocal fold position such that spontaneous voicing is possible, as in vowels, liquids, nasals and laterals. Its opposite is non-sonorant (or obstruent), referring to sounds where there is a stricture impeding the airflow, as in plosives, fricatives and affricates.

乔姆斯基和哈勒在其音系学的区别特征理论中确立的主要音类特征之一，用来描写发音方式的变化，响音从发音上定义为用相对不受阻的气流、声带取可自发带声位置时发出的音，例如元音、流音、鼻音和边音。与非响音或阻塞音对立，后者指有制流阻碍气流的音，如破裂音、擦音和塞擦音。
