Do you mean with an American accent? I hope you don't think British and American English are two separate languages and you have to choose one or the other. They are the same language with some difference of vocabulary, minor spelling differences and accent differences.

Don't worry about the difference. It's mostly just an accident of history that we speak about "British English" and "American English." In the United States, if the civil war of 1860-64 had turned out differently, we would be two separate countries and we would probably have separate dictionaries of "Union English" and "Confederate English."
