This is very true -- I always have an amazing tendency to talk faster than normal when presenting, and I find that taking the time to calm yourself before talking is effective. But you can always seem to catch people's eccentricities too; I always seem to end up scratching my right ear while talking, and have no idea I was doing it until people ask why my ear was so itchy. I'll try deeper tones in the future. Darth Vader gets respect, period.
