辅助动作

One of the types of sound feature set up by Chomsky and Halle in their distinctive feature theory of phonology, to handle variations in manner of articulation. They are subdivided into suction and pressure types, a distinction made on the basis of the ingressive or egressive glottal or velar movement involved in sounds with two simultaneous closure, as in implosives, ejectives and clicks.

乔姆斯基和哈勒在其音系学的区别特征理论中确立的语音特征之一，用来描写发音方式的变化。辅助动作分为吸和挤压两类，是按发音时有两个同时闭塞时声门或软腭的动作是内吸还是外呼来区分的，如内破音，挤喉音、吸气音。
