Trill

颤音

A term in the phonetic classification of consonant sounds on the basis of their manner of articulation: also known as a trilled consonant, or a roll, ‘trill’ refers to any sound made by the rapid tapping of one organ of articulation against another. (Vocal-fold vibration is not included in such a definition.) Several accents of English use the trilled r, as in Welsh and Scots. French and German are examples of languages which have a uvular trill. The trill may also be accompanied by audible friction, and would then be called a ‘fricative trill’. Bilabial trills are also possible, as when one makes a ‘freezing’ noise, brrr [B], or imitates a car engine.

语音学按发音方式给辅音分类的术语，也称作“颤”辅音或滚音。“颤音”指一个发音器官急速轻拍另一个发音器官发出的音。（声带振动不在这个定义之内。）有几种英语口音有颤音r，如威尔士人和苏格兰人的口音。法语和德语以及其他一些语言是有一小舌颤音的语言。颤音也可伴有可闻摩擦，这样的颤音称作“擦颤音”。也可以有双唇颤音，如发“哆嗦”噪音brrr[B]，或模仿汽车引擎的声音。
