By speaking rapidly, you will only loose your audience (imagine a scientific talk given by an auctioneer) by not allowing the audience sufficient time to absorb the information. Although it seems slow, a rate of about 100 words per minute is optimal for a presentation. By contrast, converstion rates run around 200 words per minute. Work on speaking slowly and clearly, and pause frequently to allow your audience time to process information. For instance, give the audience a few seconds to look at a slide after you project it. Don't start speaking right away, since they will still be looking at the slide and not listening to you.
