What are the phonetic symbols?

All the phonetic symbols are as follows:

International phonetic symbols strictly stipulate the principle of "one symbol and one phoneme", that is, "one phoneme and one symbol and one phoneme" is an essential pronunciation method for reading English words well.

In languages that use pinyin schemes, the same letter is often pronounced in different words. For example, the "I" in English like and lit is phonetic with international phonetic symbols, which are [a? ] and [e], another example is: A of bān (class) and bāng (state) in Putonghua, which are respectively [a] and [e] in international phonetic symbols.

In addition, in different languages, the same sound has different spellings. For example, English sh, French ch, German sch, Polish sz, Czech s, are actually all international phonetic symbols [? ] sound.

These are the advantages of international phonetic symbols, that is, they can record and distinguish sounds more scientifically and accurately (there are 72 consonants and 32 vowels in the phonetic symbols on the pass list, which is enough to mark sounds). The arrangement of international phonetic symbols is easy to analyze and master (consonants are roughly positioned according to the pronunciation position and pronunciation method, and vowels are positioned according to the position of the tongue).
