What are the four character words that contain vowel letters

There are five vowel letters in English: 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.

: The pronunciation needs to be fully open, the lips are natural, the base of the tongue is retracted, the posterior sound, the long vowel, and the letter combination ar pronounce this sound. u: The tongue is the same as u, but slightly lower than u, and the lip is smaller, more prominent, and longer vowel than u.

The Wonderful Use of Vowel Letters in English Words:

In English words, vowel substitution is a common occurrence. Because vowel letters have a relatively low status in English words, they tend to be an aid to pronunciation and do not affect the meaning of the word itself, so it can be replaced or omitted. Word makers love to use its properties to create new words.

The words created in this way are different from the original words, and at the same time can inherit the meaning of the original words, and can also derive new meanings from the original meanings.

aa、ee、ii、oo、uu。

1. There are five vowel letters in English: a, e, i, o, and u.

2. The vowels of Mandarin in Chinese are divided into two categories: single vowels (10) and compound vowels (13).

According to the front and back of the tongue position during pronunciation, it can be divided into: front vowel, middle vowel, and back vowel. The tongue is naturally flattened when the front vowel is pronounced, and the tip of the tongue touches the lower teeth.

Such as i, ü in Chinese pinyin, etc. When a middle vowel is pronounced, the middle of the tongue is raised, slightly tense, and then the air flows out of the mouth. Such as the a in Chinese pinyin, the i in English, etc.

When posterior vowels are pronounced, the base of the tongue is raised and inserted into the soft palate for pronunciation. For example, the u, o, etc. of Hantan Pinyin.

Key points of vowel phonetic transcription:

1. The essential pronunciation of vowels is to vibrate the vocal cords, which are not hindered when the airflow passes through the mouth.

2. Vowels are divided into single vowels and diphthongs.

a. When pronouncing the vowel, only need to pay attention to the lip shape and tongue position; Cell sounds are divided into front vowels, middle vowels and back vowels, and learners should pay attention to these differences: first of all, the position of the tongue during pronunciation, whether it is in the front of the mouth, the middle or the back of the mouth, and then the degree of opening and closing of the gums will lead to whether the final vowel is a semi-conjunct vowel, an open vowel, a semi-open vowel, or a conjunctive vowel.

b. The diphthongs contain two factors, one is the pronunciation from one vowel to another vowel, the difference lies in the height and front and back of the tongue, the degree of opening and closing of the gums, and the roundness and size of the lip.

3. There are a total of 20 English vowel phonetic transcriptions, and the writing of the communication letter is as follows:

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

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

a，e，i，o，u。

There are two types of 26 letters in English: one called vowel letters and the other called consonant letters. There are five vowel words: a, e, i, o, u, and the rest are consonant letters.

Vowel letters pronounce long sounds in stressed open syllables, stressed relative open syllables, and short sounds in stressed closed syllables. In Spanish and Italian in the United States, a, e, i, o, and u are vowel letters. Each vowel letter corresponds to a vowel sound, except that in Italian there is a distinction between an open and closed accent between e and i.

The degree of opening of the opening sound is relatively large, and the degree of opening of the closed syllable is relatively small.

There are 5 vowel letters, which are: a, e, i, o, and u.

These 5 vowels are a fusion of all vowels, that is to say, all vowel diphthongs, which are produced by these 5 letters and their combinations. So, the vowels usually correspond to the vowel letters.

But note that not all vowel letters are pronounced with only one sound, it may be pronounced with multiple sounds, and it should be noted here, so we understand that most of the vowels, almost all vowels will be concentrated in the pronunciation of a few letters, and these letters are vowel letters.

Overview of vowels: A vowel, also known as a vowel, is a type of phoneme, as opposed to a consonant. A vowel is a sound produced by the unhindered flow of airflow through the mouth during pronunciation.

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 pronouncing a vowel, the vocal cords inevitably vibrate is called a voiced vowel. In some languages, the vocal cords do not vibrate when vowels are pronounced, and clear vowels are produced. In some languages, some vowel letters are not pronounced in certain situations, such as in most cases, the vowel letter "e" in French is not pronounced at the end of the word.

The vowel letters of English are: a, e, i, o, and u.

Your five vowel letters are combined in different ways to form the 48 phonetic transcriptions of the middle pronunciation of English. To learn English, you must keep in mind the pronunciation rules of phonetic transcription, which is also the basis of English reading.
