1. I honestly don't know. But I don't think so? I don't usually talk to myself, even if I'm alone. I do live stream though, and still stutter. I guess that counts? 2. I still stutter regardless. Thinking of the stutter just causes the anxiety to rise, which may or may not worsen the stutter. 3. Most of the time yeah. I sometimes try to avoid certain words just because I KNOW it'll be a struggle. 4. For me, I don't stutter when doing impressions, when singing, or when doing different voices. In high stress situations is usually a coin toss if I will or not. I've sat in front of an interview panel and stuttered like Adam Sandler on the Water Boy. Yet, I've been in MUCH higher stress and anxiety situations where I've been 100% fluent.
