A master of ceremonies is often tasked with introducing a guest speaker to an audience. There are some general metrics to reach in order to give a successful introductory speech. First, it is important to use the guest speaker's name, correctly pronounced and with all attendant titles.
Customarily, the name of the speaker is given towards the conclusion of the introduction, following a short biography. In the biography, focus on accomplishments, qualifications and notable events that the guest speaker has participated in. Keep the entirety of the biography short and pertinent. An emcee is attempting to warm up an audience, making them more receptive to listen to the guest speaker. Include one or two surprising or interesting facts in the introduction. Finally, practice the speech until it is delivered easily.
