How to distinguish anterior and posterior nasals, and how to distinguish anterior and posterior nasa

1. Familiar with the pronunciation characteristics of nasal vowels The differences in the pronunciation of anterior and posterior nasal vowels are manifested in: (1) The tongue position is different. When pronouncing the anterior nasal sound n, the tip of the tongue is pressed against the upper gums, do not loosen, do not retract; When the post-nasal sound is ng, the back of the tongue rises high, and the base of the tongue retracts as hard as possible against the soft palate.

2) The mouth shape is different. The upper and lower incisors are relative when n, and the mouth shape is closed; When ng, the upper and lower incisors are a little farther away, and the mouth shape is relatively open; (3) The timbre is different. The anterior nasal n is sharper and clearer, while the posterior nasal ng is thick and loud.

2. Pronunciation tips When conducting pronunciation training, when teaching children to pronounce pre-nasal sounds, they are required to add a "?" at the end, such as an, en, in, because the initial pronunciation part of "?" is close to the end position of the anterior nasal vowel, so the child must be the anterior nasal vowel in front of the "we"; After the back nasal rhyme, you can add an "ah" such as ang, ing, eng, similarly, this "ah" is also to help the child find the end position of the back nasal rhyme, and the difference between the two pronunciation parts is the key to the difference in the pronunciation of the front and rear nasal rhymes. How do you remember which are the prenasal syllables and which are the postnasal syllables? The first is to remember the rhythm of the law, and the second is to remember the representative words next to the sound.

Rhythm and rhyme coordination rules: 1, d, t, n, l except for "tender" and "恁" (nèn), only with eng, not with en. 2. z, c, s except for "how" (zěn), "谮" (zèn), "参" (cēn), "cen" (cén), "涔" (cén), "sen" (sēn), only with eng, not with en.

Mandarin nasal vowels can be divided into two categories: those with a nasal "n" at the tip of the tongue, which are generally called "anterior nasalax finals", and those with a nasal "ng" at the base of the tongue, which are generally called "posterior nasal vowels". n, apical medium, voiced, nasal. During pronunciation, the tip of the tongue is against the upper gums, the soft palate descends, the nasal passage is opened, and the airflow vibrates the vocal cords and passes through the nasal cavity; When the obstruction is removed, the airflow breaks through the obstruction on the tip of the tongue and produces a slight stopper.

For example: which slave milk is difficult to be able peasant cow inner south you milk Nanning difficult to get male and female ability irritated muddy twisting milk cow serf grandma south and north to tune south and north war difficult to distinguish difficult to understand can speak well can do more work to make the fake come true angry and angry angry anger in the form of color ng: (tongue root) behind the tongue, voiced, nasal.

During pronunciation, the soft palate descends, opening the nasal pathway, the posterior part of the tongue is retracted against the soft palate, and the airflow vibrates the vocal cords and passes through the nasal cavity. ng is a nasal sound with two letters, which is a phoneme. ]

How can I tell the difference? Can't you hear clearly, right? Let's be confused when I say it.

If it is a confusion between the front and back nasal sounds. This is mostly due to dialect habits. It is necessary to re-learn how to pronounce them separately.

The pronunciation of the anterior and posterior nasal sounds is very different. Anterior nasal: an:

When pronouncing, pronounce the A sound first, and then gradually raise the tip of the tongue to press against the upper gum to pronounce the n sound. en: When pronouncing the voice, the E sound is pronounced first, and then the tongue surface is raised, the tip of the tongue is against the upper gum, and the air flow is discharged from the nasal cavity, and the n sound is pronounced.

in: When pronouncing, the i sound is pronounced first, and then the tip of the tongue is pressed against the back of the lower incisors, the tongue surface gradually reaches the hard palate, and the air flow is discharged from the nasal cavity, and the n sound is pronounced. un：

When pronouncing, the u sound is pronounced first, then the tip of the tongue is pressed against the upper gums, and then the n sound is pronounced, and the air flow is discharged from the nasal cavity. ün: When pronouncing, pronounce the ü sound first, then raise the tongue against the upper gums, and the air flow is discharged from the nasal cavity, pronouncing the n sound.

Posterior nasal: ang: When pronouncing, the sound of a is pronounced first, and then the base of the tongue is pressed against the upper soft palate, and the air flow is discharged from the nasal cavity, and the posterior nasal sound is pronounced at the tail of ng.

eng: When pronouncing, the E sound is pronounced first, then the tip of the tongue is against the lower gum, the base of the tongue is retracted against the soft palate to pronounce the ng sound, and the air flow is discharged from the nasal cavity. ing：

During pronunciation, the tip of the tongue touches the lower gums, the tongue surface rises to the hard palate, and the nasal cavity resonates into a sound. ong: When pronouncing, the sound of o is pronounced first, and then the base of the tongue is retracted against the soft palate, the tongue surface is raised, the lips are rounded, and the nasal cavity resonates into a sound. ]

First of all, it is necessary to correctly distinguish between the pronunciation of -n and -ng. -n is a nasal sound on the tip of the tongue, which is pronounced with the tip of the tongue against the upper gums to form a blockage, close the mouth, so that the airflow completely leaks out of the nasal cavity, and at the same time the vocal cords vibrate and produce a nasal sound. -ng is a nasal sound behind the tip of the tongue (base of the tongue), and the pronunciation site is the same as g, k, and h.

When pronouncing, use the back of the tongue against the soft palate to allow air to flow out of the nasal cavity, while the vocal cords flutter and produce a nasal sound. When practicing, do not leave the soft palate behind the tongue to prolong the voice. -n and -ng are pronounced in the same way, but the main difference is the different parts of the pronunciation.

When practicing, you should feel the blockage in different parts. Secondly, when pronouncing consonants (nasal rhymes), the pronunciation process should be clear and complete. When pronouncing a specific nasal vowel, the transition from the pronunciation state of the vowel to the consonant should be clear; The closing consonant must reach the obstruction.

For example, an and ang are pronounced. First elongate the voice and pronounce a, do not interrupt, the tongue is calmly stretched forward, the tip of the tongue reaches the upper gums, and a nasal sound appears, that is, an; Similarly, when the elongated voice is pronounced a, the tongue is calmly raised backwards, and the posterior part of the tongue reaches the soft palate, and a nasal sound appears, which is ang. There are some rules for spelling that can be memorized:

1. B, P, M, F spelling eng is not except for the word "tender", the rest of the Chinese characters are spelled eng finals. 3. D, T, and N are all spelled with "ing" finals in addition to the word "you". 4. G, K, H except for the two types of phonetic characters "Gen" and "Ken" spell en finals, the rest of the Chinese characters are spelled with eng finals.

5. Z, C, S In addition to the three commonly used words of "how", "sand (difference)", and "sen", the rest are the words next to "Zeng", all spelling eng finals. In addition, the following rules can be remembered: generally speaking, if the phonetic word is the prenasal vowel, then this series of words is usually the prenasal vowel, and vice versa.

For example, "Ling" is the back nasal vowel, and it is used as the shape and sound of the words "collar, zero, ling, ling, ring, ling, ling; "Ling" and so on are all post-nasal rhyme vowels. In the middle of this note are some individual, such as "adjacent", only the nasal sound before it is pronounced. For example, "Gen" is a pre-nasal sound, and a series of words composed of it next to the sound, such as "with, silver, yin, very, ruthless, hate, 佷" and so on are all pre-nasal words. ]

Prenasal: refers to the pinyin ending with "n", such as: an, en, in un; ?

Post-nasal: refers to the pinyin ending with "ng", such as: ang, eng, ong, ing; Flat tongue:

refers to those that begin with "z, c, s" in pinyin; ?Tongue warping: refers to pinyin that begins with "zh, ch, sh"; There's also an "r" in it

There is a big difference between the anterior and posterior nasals: the anterior nasal tail is n, and the posterior nasal tail is ng ??The anterior nasal sound ends with the tip of the tongue against the back of the upper teeth, and the posterior nasal sound is the root of the tongue to raise the base of the tongue. ]

Their pronunciation is characterized by different parts of obstruction and different openings.

1. The tail of the anterior nasal sound is n, and the tail of the posterior nasal sound is ng.

2. When pronouncing the anterior nasal sound, the vowels in front of N are generally pronounced far forward, the tip of the tongue is against the upper gums, do not loosen, do not shrink, the upper and lower incisors are relative, the mouth shape is closed, and the mouth cannot be too open when the anterior nasal sound is pronounced, so as not to enter the posterior nasal cavity backwards. Its voice is high-pitched and clear.

3. Posterior nasal sounds such as ang, eng, ing, the front vowel pronunciation is backward, the back of the tongue is raised high, the base of the tongue is retracted as much as possible, against the soft palate, the upper and lower incisors are a little farther away, and the mouth shape is relatively open. Its voice is deep and loud.

The vowel reading formula is as follows:

1) Single vowels (6): ɑ, o, e, i, u, ü.

2) Compound rhyme mothers (8): ai love, ei 欸, ui wei, ao boil, ou ou, iu you, ie yes, üe about.

3) Special vowel vowels (1): er.

4) Anterior nasal rhyme (5): an, en, in, un, ün.

5) Posterior nasal rhyme (4): angang, eng heng, ingying, ong.

6) Recognize the syllables (16) zhi (weaving), chi (eating), shi (lion), ri (day), zi (character), ci (thorn), si (silk), yi (clothes), wu (wu), yu (fish), ye (ye), yue (month), yuan (round), yin (cause), yun (cloud), ying (eagle).

Distinction overview: when pronouncing the pre-nasal sound, the vowels in front of -n are generally pronounced in the front, such as: an, en, in the pronunciation of a, e are relatively front, pronounced as the first 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 to form an obstruction with the upper gums, allowing airflow from the anterior nasal cavity to form 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 pronunciation of post-nasal sounds such as ang, eng, and ing, the vowel pronunciation in front is backward, and the pronunciation of a is originally a vowel in the back, and the vowels a and e are first retracted at the same time as the later pronunciation, and then the parabolic upward movement.

The base of the tongue and the soft palate are obstructed, allowing airflow from the posterior mouth to the nasal cavity, producing a posterior nasal sound. i is the anterior vowel of the tip of the tongue, which is pronounced in front, so when pronouncing ing, the heel of the tongue is pulled back at the same time as the i is pronounced, so that the heel of the tongue and the soft palate can be obstructed, resulting in posterior nasal resonance.

Mandarin clearly distinguishes between -n and -ng as two sets of finals. The finals formed by -n are called anterior nasal finals, and the finals formed by -ng are called postnasal finals.

The methods of distinguishing anterior nasal and posterior nasal sounds are: tongue twister practice differentiation, contrast practice differentiation, and classification and notation.

1. Practice tongue twister differentiation.

2. Comparative practice differentiation.

When practicing, find some nasal sounds before and after to compare them, such as "Wen" and "Weng", "Xin" and "Xing", etc.

3. Classification and notation.

For example, "dingding", the corresponding "ding, staring, nailing, hall, top" are all post-nasal sounds. And so on, the relevant biases can be followed in this way. If you can't distinguish the pronunciation of Chinese characters with finals an and ang, remember that all Chinese characters with the following sounds are generally pronounced nasal.

Expansion:

The pronunciation technique of the anterior nasal n is as follows: the tongue is pressed against the gums at the end of the pronunciation, the tongue and the gums are completely blocked in the mouth, and the soft palate is drooping to ventilate the nasal cavity.

The pronunciation technique of the posterior nasal sound ng is to pull the tongue heel back to obstruct the base of the tongue and the soft palate, so that the airflow enters the nasal cavity from the posterior mouth and produces the posterior nasal sound.

The finals formed by -n are called anterior nasal finals, and the finals formed by -ng are called postnasal finals.

There are sixteen Nasal Finals in Mandarin, namely an ian uan üan en in uen ün ang iang uang eng ing ong ueng iong. Mandarin clearly distinguishes -n and -ng as two sets of finals at the end of the rhyme. The finals formed by -n are called anterior nasal finals, and the finals formed by -ng are called postnasal finals.

The pronunciation technique of -n is that the tongue is pressed against the gums at the end of the pronunciation, the tongue and the gums are completely blocked in the mouth, and the soft palate is drooping to ventilate the nasal cavity.
