1. Phonetic transcription (English: phonetic transcription) is the use of symbols or marks to mark the pronunciation and intonation of words, which can also be called phonetic transcription or phonetic symbols. There are two main types of phonetic symbols, one is in the Latin alphabet.

Basic phonetic symbols such as the International Phonetic Alphabet.

Chinese Pinyin, General Pinyin, this category is usually called Pinyin; The other type is the symbols created according to the characteristics of the original language, such as Chinese character phonetic symbols.

This category is often referred to as phonetic symbols. The phonetic symbols are also referred to as Zhuyin as opposed to pinyin.

2. Phonetic transcription is to record phonemes.

is a phoneme-based symbol. It was formulated on the principle that a phoneme is represented by only one phonetic transcription, and a phonetic transcription represents only one phoneme. Such as the Chinese pinyin alphabet.

Wechsler Phonetic Transcription and International Phonetic Alphabet in English, etc. In the narrow sense"Phonetic transcription"This means the phonetic alphabet of the English language.

There are two types of diphthongs:1. Closed diphthong: its second component is i or u: ei ai au

ei〕——wait

ai〕——white

au〕——out

2. Concentrated diphthongs: its second component is i u i —hear

эairuэ〕—tour

The diphthongic phoneme is made up of two vowels, and when pronounced, one vowel slides from one vowel to the other, and the mouth shape changes. The previous vowel is pronounced clearly and loudly and for a long time; The latter vowel is vaguely pronounced and weak, and the duration is short. Three points to pay special attention to are:

1) Do not disconnect the two notes before and after, but coherently form a whole.

2) Don't ignore the latter vowel because it's shortly pronounced.

3) The sliding process should be complete and the time should be sufficient when pronouncing.

The eight diphthongs are pronounced as: [ei], [ai], [i], [au], [u], [i], u].

Diphthongs, in phonetics, refers to two vowels that are united, and they appear as a whole. There is a smooth transition, that is, the remorse pronunciation in the diphthongs involves two tongue positions that are not exactly the same, and slides from one tongue to the other.

Phonetics is a sub-discipline of linguistics that studies the sounds of speech (i.e., speech). Phonetics, in the narrow sense, corresponds to the English word phonetics, which focuses on the specific nature of phonetics and the methods by which they are produced, as opposed to phonology (or phonology), which studies the abstract rules and phonological systems by which phonemic or phonetic distinguishing features operate in a language. Phonetics, in a broad sense, refers to the sum of these two aspects of research.

This article is about phonetics in the narrow sense.
