If you are truly serious about improving your public speaking, then consider video taping yourself. You’ll be amazed at how well you do some things, and you’ll find areas for improvement that you never imagined.
After many years of teaching advanced public speaking skills, I still watch the videos of my presentations and I ALWAYS find areas for improvement and little things that make me laugh.
Video recording has an extra bonus for those of us who perform the same presentation multiple times. I wish I were a naturally funny person, because adding humor does wonders for your presentation. However, even though I’m not a comedian, I still get lucky with a funny line here or there. When I critique my presentations, I’ll always make note when the audience laughs. I write that line down and use it again. After a while, it appears that I actually have some wit.
Those who are serious about public speaking will find great benefit to recording their presentations. If video is too cumbersome for you, consider a digital audio recorder with a lavaliere mic – small investment with a big return.
