We have a number of tools at our disposal as we work to make compelling sales presentations, including our presentation media and delivery style. Often we work hard on getting these things right, but overlook the vehicle that will get our message across - our voice. We've all had to sit through monotone presenters who droned on and on, rarely changing pitch or volume. We can't afford to be one of these presenters. Here are a few ideas to help you use your voice as a powerful tool:

First, tape yourself. How we sound to ourselves can be different than how we sound to our audience. Record an entire presentation rehearsal session, play it back, and make note of your volume, pace and tone.

Next, use volume as a tool to make key points and capture attention. This can be done purposefully by changing volume over the course of a presentation: getting louder or getting quieter. Many of us have seen enthusiastic, effective presenters bring their voices almost to a whisper to make a key point.

Then note your pace and tone. Don't fall into a predictable pattern - you'll lull the audience to sleep. Modulate pace and tone to hold their attention.

Lastly, be sure to work on your breathing. This sounds simple, but nothing ruins a presentation faster than a speaker who runs out of air and finishes a sentence with an inaudible gasp!
