What is anterior and posterior nasal and what does anterior and posterior nasal mean

Note that the n sound is that the tip of the tongue and the front edge of the tongue against the gums make a nasal sound, the rest of the tongue leaves the palate and the ng sound is the base of the tongue against the soft palate, the other parts of the tongue are still placed at the bottom of the mouth, and the mouth should not be lazy when practicing, pay attention to the nasal vowels need to move from the vowels a, o, e to n, ng, and the mouth shape is reduced (especially an ang) until a pure anterior and posterior nasal sound is made.

And you should feel that the a sound in the vowel an is coming from the front of the mouth, the mouth is wide open and the tongue is stretched forward, and the tip of the tongue is against the lower incisors; The A sound in the ang is made from the back of the mouth, the mouth is wide open and the tongue is retracted, and the tip of the tongue is away from the lower gums. There is also such a difference between en and eng, but it is not so obvious. The i in in,ing is basically the same, but in order to emphasize the difference, ing can be slightly pronounced as the sound of ieng.

First practice distinguishing an ang, then distinguish en eng, and finally in can't distinguish others will feel that your accent is very strong, and the difference between en eng and in ing is not much to affect communication.

Let's take an analogy. Tone yin heart xin [anterior nasal].

英 ying 星 xing 【後nasal sound】The post-nasal sound is exaggerated, and it will be a bit of a hmmer sound. Hehe.

When pronouncing the pre-nasal sound, the vowels in front of -n are generally pronounced in the front part, such as: an, en, in the pronunciation of a, e are relatively forward, pronounced as the front a, e is pronounced as the middle e, i is originally the tip of the tongue before the vowel, the pronunciation is in front, in the process of vowel pronunciation, the tip of the tongue is gradually raised up and the upper gums form an obstruction, so that the airflow from the anterior nasal cavity is formed, forming the anterior nasal. The anterior nasal sound should not be pronounced too wide in the mouth to avoid airflow backward into the posterior nasal cavity.

The anterior nasal sound refers to the finals with n as the ending in pinyinThere are eight prenasal vowels in Mandarin, namely an, ian, uan, üan, en, in, uen, and ün.
