Practice makes perfect. Practicing a lot and deeply understanding the content of the speech you are planning to say will help boost your confidence. You can also perform your speech in front of a fake audience in your room as a form of practice. Your confidence will build up gradually after a few tries at public speaking so even if you make a mistake or two never give up.
