7. Know your speech
This sounds obvious, but it's crucial that you're very, very familiar with your remarks. That means practicing it several times or even memorizing it if you can, all while paying particular attention to your pacing. Most people talk in a slower and more stilted manner in front of people compared to how they would in casual conversation. Practicing will keep you from seeming stiff up there.
8. Control your pauses
If you find yourself pausing for any reason, hold it for at least 10 seconds. Pauses of two to three seconds make it seem as though you’re stumbling, while a long one seems intentional and will catch even the most uninterested peoples’ attention.
