There are several practical tools:
1. When you walk to the stage breathe deeply, and walk at a normal pace with a straight back. Avoid rushing.
2. Once you are on the stage smile and use open body language, open your hands, and greet the audience, again do not slouch, stay straight.
3. Create eye contact with your audience. Here is some interesting advice from a popular performer: If you are a man look at women as if you want to have sex with every woman in the room.
4. Start your speech with a loud voice; stress keywords and use pauses.
5. Avoid rushed speech. Articulate well.
