Most of us have that problem and it's not going to go away completely. We can improve, if we want and take a few simple measures. Here are a few things I can think of: 1) (as many suggested above), make American friends, hang out with them, talk to them more. 2) Listen to them attentively how they say each word---one at a time. Find out where/how you pronounce that word wrong. For example, Broccoli. We call it "borocauli". Americans call it "brokli". Once you know how they pronounce a difficult word, silently repeat it many times. Use it when you can by pronuncing it the American way. Do it with other words you have problem with. 3) Listen to NPR, watch CNN and other program. 4) When you hear someone pronounce a word differently (more accurately or in the American way), repeat it silently. 5) If you have a good American friend, you can ask him/her to correct you totally ruin some words when you pronounce. Don't feel ashamed when they do that. Take it as an opportunity to improve. Because it's your friend catching you. 6) Some colleges, universities, and churches have a program called Accent Reducer (or something similar). In those classes, you speak and others analyse your pronunciation and help you improve it. 7) Remember that some accent is considered "Very Sexy" by a lot of American girls. 8) If possible, find a part-time job that requires you to be on the phones most of the time (for example customer service or call center). This helps a lot. This much should already help you a whole lot. DP.
