hej, thanks for upping this post! It is something I was also thinking about a lot recently. Who actually determines that a pronunciation is the "correct" one. i wanna thrown an observation into this:
English belongs to all of us now. If you are happy with your pronunciation, you are good. If someone says to you: "oh, your pronunciation is incorrect" this person needs a holiday!

Who defines, whats right whats wrong. Adding the fact that English has become a most random language.

If you look at those words: "read" can be pronounced as "reed" or as simply "red" as in past tense. Still they spell it the same "read"?? Or "meet" and "meat", identical in pronunciation, only the context and syntax can help. How about "break" and "brake"? You get me? Random!!

English has got latin in its core (from history right?), who wld oppose something that beautiful as a re.latinisation of English.

If you worry about the tone/sound of your english, if imitation is your goal?, then practice is the way i guess. But I think we should move on from this, and clarify in any professional context, before english people get controlling about other ppls pronunciation. The most sloppy english speakers are prob the English themselves. Ever been to Liverpool? I wanna go hear this live 360C°..
