Videos about upvoice and other things to avoid

Communication is divided into three parts - Words, Vocal Elements, and Nonverbal Elements

These parts are not equal partners in communication. Their contribution is roughly

  • Words ~7%
  • Vocal Elements ~38%
  • Nonverbal Elements ~55%

In other words, vocal elements convey roughly 5 times more information than words. And nonverbal elements convey roughly 8 times more information than words. Therefore, it is extremely important that all the parts work together in communicating a message.

Below are seven videos providing examples of when the vocal elements doesn't support the words. I call it upvoice but others call it uptalking or high rising terminals.
