I hear that it is very difficult to show emotion or passion when you’re delivering a speech to an empty room, in front of a video camera, unless you’r an actor.
I could do it and so could most people. The trick is to edit the speech down to half the size and slow down. Pause a few times. And say it like you actually mean it, not like you are reading meaningless syllables. They could stand a person next to the camera and have him SAY it to that person, not just read.
