塞音（爆破音、闭塞音）。辅音发音方法的一种。发音时气流通路闭塞，然后突然打开发出噪音。一般的鼻音也可以归入塞音，因为发音时气流通过鼻腔，但是口腔中的气流信道被阻碍。

In phonetics, a stop, also known as a plosive or oral occlusive, is a consonant in which the vocal tract is blocked so that all airflow ceases.

The occlusion may be made with the tongue blade ([t], [d]) or body ([k], [ɡ]), lips ([p], [b]), or glottis ([ʔ]). Stops contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in /m/ and /n/, and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.
