I think some PSDs are going to have some resistance about working with a revoicer. I'd call it denial. People just can't admit how difficult their speech is to understand. When I was seven years old, I heard a tape recording of my speech for the first time. Hearing speech as normal adds to the denial.
People have a great deal of difficulty accepting their disability.
Our culture encourages them to do everything they can to become normal. The way the public looks at people with disabilities is they tell us the first thing we should want is to be able-bodied. They assume that we want to be able-bodied. It's a logical assumption because they project their fear of having a disability on those who do. They think everyone feels the same and would rather be able-bodied.
