Why there are multiple pronunciations of English vowels

The original question should be why the vowel letters in English have multiple pronunciations?

Simple, historical reasons!

Complication: Before the Wanba people, people could speak first, and then there were hieroglyphs, and later people found it easier to use symbols to indicate pronunciation, so they changed the hieroglyphs to consonant letters. Later, it was discovered that all syllables could be represented in one spelling with consonants + vowels, and there were vowel letters.

However, no matter what kind of speech you speak, the consonants are not easy to change, because there are restrictions on the pronunciation parts, but the vowels change back and forth, the tongue is high and low, the mouth is bigger and smaller, and the round is flat, so the vowels are more. However, the vowel letters have been fixed, so they have to use two or three letter combinations to represent different vowels.

This has resulted in a phenomenon of fewer vowel letters and more vowels.

Progress improves.

Are you talking about phonetic vowels or alphabetic vowels, and there is only one way to pronounce phonetic vowels, and letters such as a e and so on, so that you can distinguish the pronunciation of different words, so as not to cause ambiguity, such as bed, bad

Speech is the sound form in which people use sound forms to identify the meaning of words and sentences, so as to smoothly realize communication. Correct pronunciation, especially vowel phonemes, is not only a beautiful package of language, but also plays an important role in distinguishing the meaning of words.

In short, the different pronunciations of vowels not only reflect the wonderful art of phonetics, but also have practical significance to achieve accurate recognition of communication.

The letters that make e are: f [ef], l [el], m [em], n [en], s [es].

2. The letter of i: is: b [bi:

c [si:] d [di:] e [i:

g [d3i:] p [pi:]、t [ti:

v [vi:] z [zi:]。

3. The letter of a: has: r [ɑ

4. The letters that pronounce u: q [kju:], u [ju:] w [d blju:].

5. The letters of ei are: a [ei], h [eit] j [d3ei], k [kei].

6. There are no letters for ai and eu.

Summary. Hello, there are 20 vowels in English, and the details are as follows:

How many vowels does English have?

Hello, there are 20 vowels in English, and the details are as follows:

12 monophthongs: 12 monophthongs: ɑ:i: u: long vowels; e is a short vowel. There is a correspondence between long and short vowels.

Front vowel: [i:] i] [e] middle vowel:

Post vowel: [u:] u] [a:

When pronouncing, vowels with the same tongue position, lip shape, and opening are called unit sounds. When the unit sound is pronounced, it can be divided into three categories: front vowel, back vowel and middle vowel according to the position of the tongue bulge. The highest point of the tongue is in the front of the mouth when pronouncing prevowels; When pronouncing posterior vowels, the highest point of the tongue is at the back of the mouth; The highest point of the tongue is in the middle of the mouth when vowels are pronounced.

The second component of a conjunctive diphthong is the conjunctive vowel, i.e. and In English, there are 5 conjunctive diphthongs, namely: a e a

The second component of the concentrated diphthong is the middle vowel, that is, in English, there are three concentrated diphthongs, namely: e

How many diphthongs are there.

8 diphthongs.

There are 20 vowels in English, divided into 12 vowels and 8 diphthongs.

Vowel parts: vowels: [i:], i], [answer[ ]u:], u], [e], [

Diphthongs: [ei], [ai], [i], [i], u], au], u].

There are 28 consonants.

p]、[b] 、t]、[d]、[k]、[g]、[f]、[v]、[s]、[z]、[tʃ]、dʒ]、tr]、[dr]、[ts]、[dz]、[m]、[n]、[h]、[l]、[r]、[j]、[w]

Divided into English vowels and American vowels:1. English vowels.

20 in total) vowels: i: e u:

Diphthong: a e a e

2. American vowels.

18 in total) vowels: i e o u

Diphthong: a a

Note (1): In American sounds, it is sometimes customary to pronounce the position of the vowel o as a diphthong, and the position of the vowel e as a diphthong.

Note (2): Since the same vowel is generally longer before the voiced consonant than before the clear consonant, and the stressed syllable is generally longer than the weaker syllable, the American phonetic alphabet does not need to be marked with the long vowel symbol in the British phonetic alphabet This is the biggest difference between the British phonetic alphabet and the American phonetic transcription.

In English, there are five vowels: a, e, i, o, and u.

The vowel alphabet, or vowel letter, refers to the alphabet that plays a role in the sound of a language. The vowel sound is also called "vowel". There are 48 phonemes in the International Phonetic Alphabet (IPA), including 20 vowel phonemes and 28 consonant phonemes.

Categorizing Letters The 26 letters of the English language are divided into two types: one called vowel letters and the other called consonant letters. The vowel letters are:

a, e, i, o, u, and the rest are consonants. Classify letters according to their pronunciation commonalities, and then summarize the pronunciation rules of letter names, from which you can intuitively learn the seven vowel phonemes.

There are five vowel letters in English: a, e, i, o, and u. When pronouncing the anterior vowel, the highest part of the tongue moves towards the front of the mouth and arches slightly. When the posterior vowel is pronounced, the back of the tongue is raised towards the soft palate.

The position and shape of the lips is the third criterion for vowel classification. Half vowels are pronounced in the same way as vowels.

Consonant part:

p], [b], t], [d], [k], [g], [f], [v], [s], [z], [tr], [dr], [ts], [dz], [m], [n], [h], [l], [r], [j], [w] clear consonants are the number of vocal cords that do not vibrate: [p], [t], [k], [f], [s], [tr], [ts], [h] voiced consonants are phonetic transcriptions that can cause vocal cord vibrations, and the rest are voiced consonants except clear consonants. The 48 English phonetic transcriptions are like 60 Chinese pinyin, as long as you master them proficiently, it will play a considerable role in learning spoken English.

A few concepts about phonetics: Phoneme: The smallest unit of sound, there are 48 phonemes in English.

Syllable: A unit of pronunciation made up of vowels and consonants. Vowel:

The sound is loud, it is a musical sound, and the airflow in the mouth is unobstructed, which is the main component of syllables. There are 20 vowels in English. Consonants:

The pronunciation is not loud and is noise, the airflow in the mouth is obstructed, it is not an important part of the syllables, and there are 28 consonants in English.

Vowels: [i:], i], [u:], u], [e], [

Diphthongs: [ei], [ai], [i], [i], u], au], u].

There are 28 consonants.

p]、[b] 、t]、[d]、[k]、[g]、[f]、[v]、[s]、[z]、[tʃ]、dʒ]、tr]、[dr]、[ts]、[dz]、[m]、[n]、[h]、[l]、[r]、[j]、[w]

English Phonetic Transcription. The English phonetic transcription is a symbol that records phonemes, and it is a phoneme-writing symbol, and its formulation principle is: a phoneme is represented by only one phoneme, and a phoneme only represents a phoneme.

English is a phonetic script, and the letters express phonetics. However, English has more than 40 pronunciations and only 26 letters. In order to accurately identify pronunciation, phonetic symbols are introduced, which are called phonetic symbols.

There are two types of IPA: the British Phonetic Alphabet (DJ Phonetic Alphabet) and the American Phonetic Alphabet (Phonetic Alphabet).
