pitch and tempo for effective presentation
If you're male, your voice will have a lower pitch than most of your female friends. If you are very slender, you will probably not have as much vocal resonance as someone with a larger chest cavity. But don't despair. There are many features of your voice that you can change with a little practice and if you are going to be giving a presentation, a little bit of vocal warm-up may be all the practice you will need to sound dramatically better.

If you can, have a friend sit at the back of the room and see if the friend can hear you. If you don't have a friend who can help you, record your efforts on a tape recorder that you can playback to see if you are achieving your volume goals.
If you feel comfortable producing individual words in this manner, move up to entire sentences, and then paragraphs. Also, practice varying your volume. For important words, increase the volume making the words quite loud, and then decrease the volume to a very soft, but still audible level.
Second, tempo refers to the speed at which you speakhow fast or how slow. Most speakers who give presentations speak too fast. When you are practicing, you might try timing yourself. A nice comfortable tempo is around 140 to 180 words per minute. If you speak...
