How to distinguish between a front vowel, a middle vowel, and a back vowel?

1. The number of vowels is different:

1.4 front vowels : i: i e

2.3 middle vowels: , ,

3.6 back vowels:/ u / / u :/ / ɔ / / ɔ:/ / λ / / a: /

Second, the pronunciation is different:

1.When pronouncing a prevowel, the pronunciation is close to the front of the mouth.

2.When pronouncing a middle vowel, the pronunciation is close to the middle of the mouth.

3.When pronouncing a posterior vowel, the pronunciation is close to the front and back of the mouth.

Third, the meaning is different.

1.The so-called anterior vowel means that the front of the tongue should be used for pronunciation, that is, the front of the tongue should be raised towards the hard palate, the tip of the tongue should be against the lower teeth, and the mouth should be flattened and not rounded. The four front vowels are pronounced [i:

The anterior part of the tongue is raised highest, and the gums are nearly fully closed. The front of the tongue is slightly lower than [i:] and the gums are slightly larger.

The distance between the upper and lower teeth is approximately enough to accommodate a small fingertip. When pronouncing the third anterior vowel [e], the front of the tongue is more advanced than [i], and the gums are larger. The distance between the upper and lower teeth is approximately equivalent to the tip of an index finger.

The front of the tongue is lowest when the fourth front vowel [ ] is pronounced, and the gums are the largest. The distance between the upper and lower teeth is approximately equivalent to an index finger plus a middle finger.

2.The so-called posterior vowel means that the posterior part of the tongue should be used for pronunciation, that is, the back of the tongue should be towards the soft palate.

Lift. The tip of the tongue can be pronounced without touching the lower teeth when pronouncing the back vowel. Except for the post-vowel [ɑ:

In addition to the middle and regular lips, the other four sounds should be rounded, and the mouth should be rounded when pronouncing. Individual sounds such as [u] [u:] lips should also protrude forward.

Second, pay attention to the tongue position of the posterior vowel. Of the five back vowel sounds, [ɑ: has the lowest tongue position and the largest opening.

3.The so-called middle vowel means that the middle of the tongue should be used in pronunciation, that is, the middle of the tongue should be slightly raised, the tip of the tongue can be lightly touched against the lower teeth, and the mouth shape should be flat or medium.

The difference between the front vowels, the middle vowels, and the back vowels is that the parts of the hair and the wood are different.

1. Front vowels: The highest point of the tongue is in the front of the tongue when pronouncing.

2. Middle vowels: When pronouncing, the highest point of the lower position is in the middle, and the tip of the tongue should touch the lower teeth or slightly away from the lower gums.

3. Post-vowel sound: When pronouncing, the highest point of the bowing position is in the back, and the body must be retracted, and the tip of the tongue must leave the lower gums.

The difference between high vowels, semi-high vowels, semi-low vowels, and low vowels:

According to the height of the tongue during pronunciation, it can be divided into: high vowel, semi-high vowel, semi-low vowel, low vowel, etc. Tachibana good.

Longitudinally, we can divide the longitudinal line segments that represent the distance between the tongue and the palate.

The ends of the line segment and the two dividing points are the four vowels of different heights represented by the height of the tongue. Of course, in specific linguistic studies, this graph can be more subdivided if necessary. The tongue position can be thought of as the distance between the tongue and the palate.

The closer the distance, the higher the tongue position. The farther it goes, the more it goes.

The height of the vowel depends on the distance between the tongue and the palate, not the size of the mouth, because the size of the mouth does not necessarily cause the tongue to be high or low. If it is made, the distance between the tongue and the palate is large.

The differences are as follows:

1. 4 front vowels : i: i e.

When pronouncing a prevowel, the pronunciation is close to the front of the mouth.

2. 2 middle vowels: : .

When pronouncing a middle vowel, the pronunciation is close to the middle of the mouth.

3. 6 back vowels:/ u / / u :/ / ɔ / / ɔ:/ / λ / / a: /。

When pronouncing a posterior vowel, the pronunciation is close to the front and back of the mouth.

International phonetic alphabet is a recorded phoneme.

, which is also a phoneme-based symbol, is used in linguistics. The proposer of the phonetic alphabet is H. Svester P. Parcy Jones. English Phonetic Transcription.

There are 20 vowels and 28 consonants in it, for a total of 48.

Vowels: ɑ:i:] u:][e] [.]

ei]、[ai]、[i]、[iə]、uə]、au] 、u]。

Consonants: p], [b], t], [d], [k], [g], [f], [v], [s], [z], [t], d].

tr]、[dr]、[ts]、[dz]、[m]、[n]、[h]、[l]、[r]、[j]、[w]。

The difference between the vowels in the front vowel and the back vowel is the tongue position of the pronunciation. When pronouncing a prevowel, the pronunciation is close to the front of the mouth. When pronouncing a middle vowel, the pronunciation is close to the middle of the mouth.

When pronouncing a posterior vowel, the pronunciation is close to the front and back of the mouth. When pronouncing a prevowel, the anterior part of the tongue works, the middle part of the tongue of the middle vowel does, and the posterior part of the tongue of the posterior vowel does.

Introduction to vowels

Vowels, also known as vowels.

It's phonemes. , as opposed to a consonant. A vowel is a sound produced by the unhindered flow of air through the mouth during the pronunciation process.

When vowels are pronounced, the airflow from the lungs through the glottis hits the vocal cords, causing the vocal cords to vibrate evenly, and then the tremolo airflow passes through the mouth unhindered, producing different sounds through the adjustment of the tongue and lips. When vowels are pronounced, the vocal cords inevitably vibrate, which is called voiced vowels. There are also languages that pronounce vowels without vibrating and produce clear vowels.

Vowels are divided into front vowels, middle vowels, and back vowels. The difference between the pronunciation of the front vowel, the original sound, and the back original sound is: front vowel:

When pronouncing, the highest point of the tongue is bright, and the pants rush to the front of the tongue. Middle vowels: The highest point of the tongue is in the middle of the pronunciation, and the tip of the tongue should touch the lower teeth or be slightly away from the lower gums.

Posterior vowels: When pronouncing, the pure selling tongue is the highest, all in the back, and the body must be retracted, and the tip of the tongue must leave the lower gums.

According to the different parts of the tongue raised in the oral cavity during the pronunciation of vowels, vowels can be divided into: front vowels, front and back vowels, and middle vowels.

Front vowels: When pronouncing, the vowel hand is pronounced close to the front of the mouth;

Middle vowel: The highest point of the tongue is in the middle of the mouth. It is characterized by the constant position of the tongue, lip shape, and opening during pronunciation.

Posterior vowels: A type of vowel formed by the lifting of the back of the tongue. During pronunciation, the tongue is retracted, the tip of the tongue is downward, and the back of the tongue is raised against the soft palate, also known as soft palate vowels.

Diphthongs in phonetics refer to two vowels that are united, and they appear as a whole. There is a smooth transition, that is, the pronunciation in a diphthong involves two different tongue positions, and slides from one tongue to the other.

In the International Phonetic Alphabet (IPA), monophthongs are represented by a single letter, e.g. [ ] diphthongs are represented by two letters, such as [a], and less loud letters can be marked with a [ symbol to indicate that it is part of a diphthong, e.g. [a]e].

1. The pronunciation is different.

When pronouncing a prevowel, the pronunciation is close to the front of the mouth. When pronouncing a middle vowel, the pronunciation is close to the middle of the mouth. When pronouncing a posterior vowel, the pronunciation is close to the front and back of the mouth.

2. Pinyin is different.

Front vowels such as i, ü, etc. in Hanyu Pinyin. Middle vowels such as the a in Chinese pinyin, the i in English, etc. Post-vowel sounds such as u, o, etc. in Hanyu Pinyin.

Classification of species. 1. The vowels of socks in some languages can be divided into tongue vowels and tongue vowels. Most vowels are tongue vowels, such as [a], [e], [i], [o], [u], etc., while there is a class of apical vowels in the Chinese family that are rarely seen in other languages, and the apical vowels are tense when pronounced, including flat tongue sounds (apical front sounds) such as the finals of Hanyu Pinyin zi, ci, si, and warped tongue sounds (apical back sounds).

2. According to the airflow path, it is divided into: oral vowels and nasal vowels. Oral vowels are vowels in which the nasal pathway is blocked during pronunciation, and the airflow passes only through the mouth.

Most vowels are spoken vowels. Nasal vowels, on the other hand, are vowels in which the soft palate is lowered and air flows through the mouth and nasal cavity at the same time. Nasal vowels are mainly seen in:

French, Portuguese, Chinese, Jin, Jinan, Tibetan, Lhasa, etc.
