How would you like to improve the odds of people remembering your main points when speaking. Meaningful gestures with the appropriate vocal emphasis allow your message to be absorbed at 3 difference levels.
The words you used are heard by the ears. With the right emphasis in vocal variety gives a rhythm and with the right gesture provides visual impact. In John Medina’s book “Brian Rules: 12 Principles for Surviving and Thriving at Work, Home, and School.” he emphasizes how vision trumpets all the other senses. That is why having a repertoire of gesture to show what you are saying is so important.
When you have the words crafted in harmony with the voice you are easier to listen to, and when you bring the right body movement you will be remembered.
