Languages have typical frequencies. Different accents within a language have already frequency variations. If languages use other frequencies than your native language, then your brain needs a while to adapt to it. This is why, when we listen to a film or even a phone call, we need a moment to ‘grove in’.
As you can see in the chart below, the American English differs from the British English already considerably. So if you intend to work on your pronunciation and decide whether you would want to sound more British or American, then it is not just about pronunciation of a few letters or a few words that may be different. It is much more a full package of
- pronunciation of certain letters and combination of letters
- different words for the same thing
- sentence melody
As [wikipopup]George Bernard Shaw[/wikipopup] said: “England and America are two countries separated by a common language”.
