Dynamic range to a microphone is the range of sound that can be picked up. Dynamic range for public speaking is the ability to incorporate the range of speaker skills in public speaking.

The speaker skills is a long list of various speech qualities possible with the human voice. The list includes things like...

Pace

Pitch

Power

Volume

Rapport

Emphasis

Modulation

Enthusiasm

Naturalness

Clarity of Speech

Accurate Pronunciation

Mastery of these and other skills is essential to develop as a dynamic public speaker. Consider just three of the skills and how they can enhance your public speaking.

Pace, pitch and power are three of the most important to master in order to grow as a speaker.

Pace: The speed at which you speak. It is important to be able to increase and decrease the speed depending on the content of the speech.

Adjusting the pace can also help create dramatic effect or emphasize a point. Speak too fast and the audience will not be able to keep up with you. Speak too slow and you will bore them. Speak at a varied pace and keep the audience attention.

To practice, get a book and read out loud. Start slow and speed up and then slow down at random. Then practice doing it appropriately to the story being read.

Pitch: The tonal quality is often given little consideration by inexperienced speakers. When under stress our voices often tighten up. Knowing this can help us control the change by controlling how we view stress.

Likewise, slight changes in the pitch can enhance the quality of our speech.

Do not go to low or to high or else control will be lost. Lose control and annoy the ears of the audience.

Again reading a book, practice raising and lowering the pitch as you read the voice of men or women characters talking.

Power: The force behind the words we use can add a unique quality to our speech. Try it.

Speak with the softest voice possible. Then speak with the strongest voice possible.

Now try to speak with a strong voice only keeping the volume as low as possible. Likewise speak with the softest voice as loud as you can.

Next learn how to mix the three together.

Remember, this is only part of the dynamic speaking range. There are other speaking skills to be added to the mix.

Master all of them, learn to use them together and you will have mastered dynamic public speaking.
