If you want to get a good pronunciation then I recommend you watch the news on BBC and if You don't have cable tv, you can go to YouTube - Broadcast Yourself. and put the word "bbc news" in the seeker and it's going to appear a lot of news. Just watch them and notice the pronunciation the have. It's a beautiful accent.
If you just want to practice a couple of words just visit English to French, Italian & Spanish Dictionary - WordReference.com, You put the word in english and a phonetic record appear.
