Detailed explanation: Basic knowledge of English international phonetic symbols and pronunciation

When the vowel phonemes are pronounced, the airflow is emitted from the chest and passes through the vocal passage without obstruction. It is only regulated by the vocal organ. It is a dull sound.

When pronunciation of consonant phonemes occurs, the airflow is emitted from the chest cavity, passes through the vocal passages, and is obstructed by the articulators. There are two types of consonants, voiced and voiceless.

The minimum unit classification number of phonemes is 48, including 20 vowels and 28 consonants (11 unvoiced sounds and 37 voiced sounds)

The text symbol classification unit of phonetic phonemes is 5 long units, Single short unit 7, double unit 8, burst 6, grind 10, break 6, nasal 3, half 2, lingual 1

The smallest segment classification of syllable speech 1. Pure vowel syllable 2. Vowel Secondary mixed syllables 3. Unstressed consonant syllables

The composition of monosyllabic words 1. Single vowel letter 2. Single vowel letter E 3. Single vowel letter consonant 4. Multiple vowels and consonants

5. Single vowel letter and single consonant letter E 6. Single vowel letter and two consonant letters E 7. Polyphonetic letter consonant letter E

Disyllabic words 1. Have two monosyllables 2 .Stressed monosyllables and unstressed consonant syllables

Polysyllabic words 1. Have three or more monosyllables 2. Two vowel syllables and unstressed consonant syllables

Stressed syllables The loud and clear syllables read in words can be divided into 1. Open syllables 2. Closed syllables 3. r syllables 4. re syllables 5. Combined syllables

Unstressed syllables are read more vaguely in words Weak syllables can be divided into 1. Single syllables 2. Combined syllables 3. Unstressed consonant syllables 4. r syllables

Monosyllabic words are all stressed syllables, so there is no need to mark the stress mark, and the five types can be determined directly syllable.

Disyllabic words 1. Generally, verbs are stressed at the back and non-verbs are stressed at the front

2. If they are composed of monosyllabic words with unstressed consonant syllables, then the vowels are Stressed on the original word

3. If it is composed of a monosyllabic affix, it is stressed on the original word

4. If it is composed of a monosyllabic prefix, some prefixes can be stressed, forming a double reading. For example: pre-before post-after re-un-not ex-predecessor

5. If it is converted from a verb or a non-verb, it can be judged according to the original word or the part of speech after the conversion.

Polysyllabic words 1. Generally, the stress is on the third to last syllable

2. If it is composed of a two-syllable affix, the stress is on the original two-syllable word

3. If there are more than two syllables before the first stressed syllable, then the second stressed syllable will be placed on the penultimate syllable

4. If the word ends with -tion, -sion, If -ic follows the ending, the preceding vowel will be stressed

Syllabic division Monosyllabic words do not need to be divided, and their pronunciation can be determined directly

Two-syllable words 1. If the stressed syllable comes after , then at least one consonant before the stressed vowel returns to the back.

2. If the stressed vowel comes first, the subsequent consonants are judged as follows:

Structural division to form syllables Structure division to form syllables

Heavy vowels 2 are weakly auxiliary The first unit is divided into two closed syllables. The heavy unit 2r is divided into two closed syllables.

The heavy unit 3 is auxiliary. The weak unit is divided into two closed syllables. The weak unit is divided into two closed syllables. /p>

Heavy Yuan 4 Auxiliary Weak Yuan The first two and last two closed syllables are heavy Yuan r, the auxiliary weak Yuan is divided into two r syllables

The heavy Yuan 1 auxiliary weak Yuan mostly returns to the front closed syllable heavy Yuan The single r weak element is divided into two re syllables

A few open syllables after the return are special: story['stC: ri], very['veri], bury['beri], furry[f[:ri ]

Chongyuan 1 consonant le is divided into two closed syllables single, gentle, giggle, little , apple, crystal, middle, riddle, node

Syllabic category Silent E The vowel letter E is at the end of the word. If there is any vowel letter before it, the E is a silent E, such as: tie, shoe, true, see, dance, like

Open syllable 1. Absolute: ending with a single vowel 2. Relative: ending with a single vowel E 3. Ending with a single vowel E tie, bye, see, doe, tee, flee, true

Closed syllable 1. Absolute: the unit ends with one auxiliary 2. Relative: the unit ends with two auxiliaries E 3. The unit ends with two auxiliaries or more 4. Heavy element rr weak element

r Syllable 1. Absolute: The unit is single and auxiliary R car 2. Relative: The unit is single R and the consonant E ends in horse 3. The unit is single R and auxiliary is park, torch

re Syllable 1. Absolute: The unit is single and auxiliary R E pure 2. Relative: heavy unit single R weak element parent, hero, zero, serious, furious, during, fury

Letter combination 1. Unit consonant al, ew2. Multiple oo, ea 3. Multiple auxiliary oor , ear, ower, augh,tion 4. Two or more consonant letters bl, tn, kl, dn, tm

Single syllable is a syllable composed of a single vowel letter in an unstressed syllable.

The consonants m, n, and l at the end of non-stressed verses are often formed with the consonants before them. The characteristic is that they must be at the end of the word and are non-stressed verses. Such as: apple, table, autumn
