Listen English songs & try to sing them ,watch english movies with language subtitles on bottom of screen and read english newspapers ,talk to yourself in frint of amirror in english in a close room...

It requires small precautions. First, don't be conscious. Get rid of your shyness. Be a master of your vocabulary. Don't try to explain complicated ideas, without prior preparation. Do gradual work. You may take 2, 3 months. Don't always compare with other's English.

you should join some English speaking institute and try to speak in English with those who have a command over this language as it will not only improve your English but will also give you confidence.

Hello dear,Try to join any institute where u can learn speaking english at least thrice a week.Try to communicate with friends in english,read english newspapers,watch english movies.Best of luck!
