Are you aware of how much speech therapists can cost? You could end up paying thousands of dollars in your search for a cure for stammering if you go and see one of these people. I should know because I was burned by this charge! Going to see a speech therapist didn’t help me as they simply told me I would have to speak slower for the rest of my life, but I didn’t want to just do that.
I wanted to speak normally like everyone else. I studied how fluent speakers were talking and tried to copy them to improve my fluency.
