How to distinguish the front and back nasal sounds in Pinyin?

There is no distinction between the front and back nasals

1. The pinyin cannot be distinguished

There is no other way, the only way is to memorize it by rote, laziness is not enough

2 , Can't tell the difference when listening to other people's words

This is not a big problem. Anyway, you can know which word it is and what it means based on the context and context.

3. Can't pronounce it correctly when speaking

a. It doesn’t matter in daily life. You can still understand what you say even if you don’t speak accurately, and it doesn’t affect communication

b. If you are going to take the Mandarin exam, you have to practice

If you must find a method, the key is to master the essentials of pronunciation. The pronunciation of front nasal sounds and back nasal sounds is mainly distinguished by two points:

First, the obstruction parts are different, and second, the opening size is different. Same.

When pronouncing a front nasal sound, the vowel in front of -n is generally pronounced more forward than *. For example: in the pronunciation of an, en, and in, the pronunciation of a and e is relatively forward, and a is pronounced as The front a and e are pronounced as middle e, and i is originally a vowel in front of the tip of the tongue. The pronunciation is in the front. During the process of pronouncing the vowel, the tip of the tongue gradually rises to form an obstacle with the upper gums, causing the airflow to flow out of the front nasal cavity, forming a front nasal sound. When pronouncing front nasal sounds, the mouth should not be opened too wide to prevent airflow from entering the posterior nasal cavity.

For the pronunciation of back nasal sounds such as ang, eng, and ing, the preceding vowel is pronounced * after, and the a is pronounced as the back a. E is originally a vowel that is pronounced last. When the vowels a and e are pronounced at the back, the tongue heel is raised upwards, causing an obstruction between the tongue heel and the soft palate, causing the airflow to enter the nasal cavity from the back of the oral cavity, producing a back nasal sound. i is a vowel in front of the tip of the tongue and is pronounced in the front. Therefore, when pronouncing ing, the heel of the tongue must be pulled back while pronouncing i, so that the heel of the tongue and the soft palate form an obstacle, resulting in postnasal whine. How to remember which syllables are pre-nasal and which are post-nasal? The syllables of the front nasal sound are more than the syllables of the back nasal sound. In line with the principle of remembering less but not too much, we mainly remember the syllables of the back nasal sound. One is to remember the rules of phonetic and rhyme coordination, and the other is to remember the representative characters of the phonetic side. The rules of coordination between sound and rhyme:

1. d and t are only combined with eng, not en.

2. z, c, and s except "尮" (zěn), "谮" (zèn), "神" (cēn), "cen" (cén), "涔" (cén) and "sen" (sēn) ).

3. d, t, and n only match ing, not in (except for "you").

I have a complaint: I think the front and back nasals (especially in, ing, en and eng) are not important. Although I know when to use front nasal sounds and when to use back nasal sounds, I usually only pronounce the front nasal sounds. , the back nasal sound means tired (especially in and ing, en and eng).
