美语发音概述--英语发音类别

基本分类及常识

语音分元音和辅音两大类，每一个语音必定属于这两者之一。

元音

元音是一种有声音，发音时用舌头和嘴唇使口腔定形，声带振动。同时气流从咽腔和口腔不断流出，不受阻碍，也没有变狭窄，因而听不出摩擦。

辅音

（在正常言语中）除元音外所有的其它音都叫辅音。一部分辅音发音时，气流不通过口腔，如[m]；另一部分辅音发音时，气流在通过口腔时，受到这样或那样的阻碍，或在口腔中的某个点受到摩擦。

元音分类A

根据发音时舌头在口腔中抬起的部位不同，我们把单素元音分为前元音、中元音和后元音。

例如：[1] 前元音，口型舒展

[u:] 后元音，口型收拢

前元音

舌前部向硬颚抬起时发出的元音叫前元音。

前元音(Front Vowels)主要有：

英式英语：[i:] [i] [e] [1]

美式英语：[i] [I] [A] [1]

舌中部向硬颚抬起时发出的元音叫中元音。

元音分类B

根据构成元音的音素的不同，我们把元音分为12个单元音（monophthongs）和8个双元音（diphthongs）。Monophthongs: [i:] [i] [e] [1] [8] [2:] [3] [3:] [u] [u:] [4:] [4]

Diphthongs: [ei] [2i] [3i] [4u] [2u] [i4] [e4] [u4]
