Hi Rajangam, the best ways to speak english is to stand in front of the mirror and talk to your self. Look at your gestures and postures, correct them, that's how you build your self confidence and improve upon your spoken english. For example you can imitate for an interview, or may be talking to a friend, or your boss, or reciting some earlier conversations you may have in mind. Try this it always works. And always ask people around you to correct you in your grammar whenever you speak, don't shy, and don't even feel bad about others correcting you, thats how you learn things in life. Go forward and be positive, have a great learning's ahead!!
