1. What are the phonetic symbols in English?
All phonetic symbols are shown in the following figure: The International Phonetic Alphabet strictly follows the principle of "one symbol, one sound", that is, "one phoneme, one symbol, one phoneme" is an essential pronunciation method for reading English words well. In languages that use the Pinyin system, the same letter often has several pronunciations in different words. For example, in English like and lit, the "i" is pronounced using the International Phonetic Alphabet as [a ɪ] and [e], respectively. Similarly, in Mandarin b ā n (class) and b ā ng (state), the "a" is pronounced using the International Phonetic Alphabet as [a] and [e], respectively. In addition, the same sound has different spellings in different languages. For example, the sh sound in English, ch sound in French, sch sound in German, sz sound in Polish, and s sound in Czech are all actually the [∝] sound in the International Phonetic Alphabet. These are the strengths of the International Phonetic Alphabet, which can scientifically and accurately record and distinguish speech sounds (there are 72 consonants and 32 vowels on the phonetic alphabet, which is roughly sufficient for annotating speech sounds). The arrangement of the International Phonetic Alphabet is convenient for analysis and mastery (consonants are roughly determined by their pronunciation location and method, with the vertical and horizontal coordinates of Kaifeng Mountain, and vowels are positioned according to their tongue position).
