Tap

触音

A term used in the phonetic classification of consonant sounds on the basis of their manner of articulation: it refers to any sound produced by a single rapid contact with the roof of the mouth by the tongue, resembling a very brief articulation of a stop. It is commonly heard in many American English pronunciations of the medial /t/ or /d/ in writer and rider. Some phoneticians distinguish between taps and flaps in terms of the articulatory movements involved.

语言学按发音方式给辅音分类的术语，指用舌单次快速接触口腔顶部发出的音，与发音很简短的塞音相像。常见于美国英语writer“作家”和rider“骑车人”中的中间音/t/或/d/的发音。有的语音学家按不同的发音动作区分触音和闪音。
