I'm basically fluent when I show my real personality?

I'm basically fluent when I show my real personality? I've noticed for a while that when I show people the real me with no filter, my stutter decreases to nearly 0. I even tested it with Call Reps from Amazon. All I did was be as free as I wanted and I didn't even stutter once. The real challenge for me is applying this face to face with people. I have trouble being social and outgoing the second I meet someone. It usually takes a while until I reach that point. Right now my focus is trying to be 100% filter free immediately and don't hold back. Does this happen for anyone else?
