What's the difference between the new English phonetic alphabet and the old one?

The specific changes are as follows, except for the changes in the text, nothing else has changed.

English phonetic symbols are constantly improving. Modern linguists believe that /tr//dr//ts//dz/ in the original DJ phonetic symbol is a consonant, not a allophone.

Therefore, unvoiced consonants (/tr//ts/) and corresponding voiced consonants (/dr//dz/) in traditional DJ phonetic symbols have been deleted from the phonetic symbols of BBC English website. So just like the consonants of the American phonetic alphabet, the British phonetic alphabet has 24 consonants.

So BBC has 44 phonetic symbols, including 24 consonants and 20 vowels.
