Vowels
l
In phonetics, a vowel is a sound in spoken language, such as English ah! [ɑː] or oh! [oʊ], pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis声门. This contrasts with consonants, such as English sh! [ʃː], where there is a constriction or closure at some point along the vocal tract. 最常用的区别元音和辅音的方法，是看一个音在它发 出的时候，是否受到发音器官的阻碍。
