The accent really isn't significant in my opinion. It can hint where you live, maybe, but its not as important. In the United States, Britain, and Australia we all carry different accents but we can all understand one another for the most part. There are places where different words are used like in America we say "he is calling us" where in Britain I think they say "he is ringing us" talking about someone calling them on a phone.

Unless there is a specific need to learn an accent, it really doesn't matter. It's more important to get the grammar right and the pronunciation. The English language is essentially the same wherever you go in the English speaking world and you'll have no trouble communicating, no matter which kind of English you decide to learn.

As a learner, you just need to focus on standard pronunciation. If you are doing English courses, you'll hear different accents in the audio recordings so you can be familiar with them. Feel free to ask your teacher where each accent comes from.

languages need time , simply listening without you feel will give accent learn the word right in the way you find it right and with time all will go just fine i spouse , good luck
