I am a speech therapist and I like to know what has worked for different people who stutter. I’ve spoken to a few different adults (through everyday life,) and it’s interesting. One grew out of it, (seemed to be related to childhood trauma,) another started to inconspicuously tap his foot for rhythm. He continued to stutter ti a degree, but when he did stutter, he stuttered fluently, so to speak. He didn’t struggle just let it go and kept on talking. He became a salesman.The oddest one was a man who went to a university program for therapy. He was asked to speak in front of a class of speech therapy students. They began to make fun and laugh at him when he began to stutter. Eventually he broke and yelled at them angrily. Of course he was fluent when he yelled (a common occurrence.) Turns out it was all a set up and the students were told to tease him. That single event changed him permanently. I never would have guessed he’d ever struggled with stuttering.
