How to give a great impromptu speech
Take your time getting ready to speak.
Don't be in too big of a hurry to stand up or make the trip to the podium. Walk slowly to your mark, being relaxed and deliberate.
Stretch the time you have and use it to prepare yourself and consider what your opening lines will be. Most of the time when you're giving an impromptu speech, you'll be singled out to say a few words on the spot.
