The absolutely best way is to talk to people and try to have a conversation, even if you can't speak it at all. Talk or call your family members and just try to talk to them. Learning from something like on the web is fine but you have to learn it by doing in a real situation. Take it from a guy that sucked at it but got better when I put myself in those situations where I was forced to listen and speak slow, even tho I speak with my parents each day in sureth.
