Your Most Powerful Tool: Your Voice

Does Your Voice Support Your Fabulous Story?

Here are some observations that researchers have made about public speakers and the voice:

  1. People respond to speakers with great vocal variety.
  2. Successful speakers will change their vocal quality to target different people in the audience.
  3. People trust speakers with a lower-pitched voice, and who speak more slowly. (Patients actually perceive as more caring doctors with these vocal qualities.)
  4. The worst thing a speaker can do is to drone on with no vocal variety.

You can have the most interesting story in the world, but if your voice does not support your story, your presentation will suffer. 

Below are two videos that dramatically show how two individuals use the voice to give themselves power, credibility and charisma
