Abrupt

突发（音）

A term sometimes used in the distinctive feature theory of phonology, as part of the phrase abrupt release: it refers to a sound released suddenly, without the acoustic turbulence of a fricative, as in plosive consonants. Its opposite is delayed release, used to characterize affricates.

有时用于音系学的区别特征理论，常见于短语突发除阻。这个短语指一个音突然除阻，没有像破裂辅音中的擦音所有的那种声学湍流。其对立术语是用来描写塞擦音的延缓除阻。
