There may be times in your career when you have to do a lot more public speaking than you are used to. Perhaps you are doing a road show around the country preparing for an initial public offering. Or maybe you have to explain a new initiative to workers at 40 plants around the world.
If you are speaking to a large group, say 500 people or more at a time, you can count on someone providing you with a microphone and speakers, so that you can be heard without yelling. If you are talking to only one or two people at a time, no amplification is needed; you can use your normal speaking voice.
