Finally, about 20 years ago, we were watching the Today show, and a professor, Ron Webster, was talking about the success of his new theory and treatment for stuttering. I turned to Annie, and said, "You should try this because it's brand new." She agreed, and went down to Webster's three-week course in Roanoke, VA. It literally changed her life.
In her first week, she learned how to speak in slow, short syllables. During the second week, they gradually sped up the rate at which she spoke, working on sounds that are particularly difficult for stutterers. The third week is a continuation of the work learned in the first two weeks. Annie reached a point where she could represent me in speeches, and speak for others with handicaps. She will always have to work on her speech, but with her courage and determination she overcomes the disability every day with phone calls and normal conversation.
