To get rid of a lisp, stand in front of a mirror and speak. Notice which sounds are most hard to pronounce. Write a paragraph that has many of the sounds that give you a problem. Stand in front of the mirror again and read the paragraph. Pronounce the words one by one and slowly. Do it several times.
