2.1.1. 口型(Mouth shape)


For vowel pronunciation, the airflow from your lungs strikes against your vocal cords through the glottis. This produces a consistent vibration that is amplified as it travels unimpeded through your mouth - the resonator cavity - before being expelled freely.


Notably, a prime organ involved here: lips - the only visible speech articulator observable when infants are learning to speak. Another organ that opens the mouth is the jaw, which, when pulled apart, enlarges the shape of the mouth.

以下是 5 个基础元音发声时的口型(嘴唇位置):

Here are the mouth shapes (or, lips positions) during enunciation of five basic vowels:

Vowels mouth shape

当然,除了嘴唇的形状之外,影响元音发声的器官还有舌面的位置、软腭的动作 —— 影响口腔内气流共振的空间 —— 不过,由于人类语言的相通属性,人们在这些基础元音的发声上都没有任何困难。

Certainly, besides the mouth, other articulators influencing vowel pronunciation include where tongue lies and what's happening with soft palate, forming a specific space that affects the resonance of airflow in the mouth. But thanks to universal linguistic attributes in humans, no one really struggles when it comes down to these basic vowels.

另外,英文的 ə 口型与 e 接近;而 æ 的口型比 e 的大一点、比 ɑ 的小一点。

Moreover, regarding English phonetics: the mouth shape for ə is similar to that for e, whereas for æ, a slightly larger opening is formed than when saying e, but smaller one compared with pronouncing ɑ.
