Fellow speaker,
When watching/listening to yourself speaking, decide what your position" on your speech is: what are you going to focus on when listening/watching the speech? For example is it the word pacing and delivery? Or the stage usage and tie-in with the stage to the speech? Whatever it is, focus in on that one thing and ignore everything else when listening/watching the speech. After you are fully aware of that thing, watch/listen to the speech again looking for something different.
Positioned,
Tim
