Pronunciation problem

Hello prabeersikdar! The best way to improve pronunciation is to listen to lots of English, whether on tv or cd's, tapes, etc. Watch English films in their original version, whenever possible. If there's any chance you have some English speakers around, just talk to them about anything. If you can't think of anything to say, ask them about their lives. Most people like talking about themselves, so it's a good listening practice. Try to imitate everything: from intonation to the movements of their mouths. You can do it in front of a mirror. It really helps, believe me!!
Hope this helps
