Relax most people experience stage fright when they stand and speak in front of a group. Breathe deeply and speak slowly to avoid shaking.
Stand with your weight balanced to avoid the feeling of shaking and trembling. If your hands shake hold them in front of you rest them on the podium or let them hang down at your sides.
Concentrate on what you are saying and the stage fright will pass.
Do not rush take your time and say each word distinctly.
