I don't stutter. Public speaking is scary as hell all the same. I typically worry that I'll fail to put my ideas across coherently; that I'll forget my presentation; that I'll sound stupid or childish; or that I'll be exposed as having a woefully inadequate knowledge of my subject matter. If presenting in a professional capacity, I am also very scared in case I misrepresent my organisation or otherwise say anything which gets me into trouble, particularly in response to unexpected questions from my audience. All of this fear compounds itself and it makes it hard to appear relaxed, and sometimes even my voice will shake and betray how nervous I am. Then I get nervous about the possibility that I might appear nervous, it's a vicious cycle.
