Difference accents by region

As you know, the English has not the same accent everywhere. You'll need to recognize and understand the accent of the person you're talking to. Is not the same, talk with someone of the United States, than talking to someone of England. Sometimes is harder to understand the British English because of their pronunciation and in English schools most of the time they teach you American English and this makes it easier to be understanded. But be careful! Not every area speaks with the same pronunciation, it will be better for you if you practice with persons that pronounced in a different way for prove yourself how much you can understand.
