Extended data:

International phonetic symbols are symbols for recording phonemes and writing phonemes, which are used in linguistics. The phonetic symbol was put forward by H. West P. Percy Jones. There are 20 vowels, 28 consonants and ***48 in the English phonetic alphabet.

The principle of making phonetic symbols is that a phoneme is represented by only one phonetic symbol, and a phonetic symbol does not just represent a phoneme. Phonetic symbols composed of two phonemes are called diphthongs, such as Chinese phonetic symbols, English Webster phonetic symbols, international phonetic symbols and so on.

There are 28 consonants:

[p]、[b]、[t]、[d]、[k]、[g]、[f]、[v]、[s]、[z]、[θ]、[？ ]、[? ]、[? 】、【t？ 】、【d？ ]

[tr]，[dr]，[ts]，[dz]，[m]，[n]，[？ ]、[h]、[l]、[r]、[j]、[w]
