Fellow speaker,
When preparing to do a speech requested by someone else (e.g., meeting planner) for some event, listen to the people involved with the event. Go to the audience members, the key players, the employees, etc., ask them questions, and listen carefully to their answers. Listening to what they have to say and then using their answers in your speech will customize your speech to the needs of your audience.
Listening in,
