Compelling professional speaking starts with inflection.

The voice that lacks inflection speaks on one tone and sounds robotic, monotonous and dull. The speaking voice has a natural range of 5 to 8 tones. It is important to use these tones as you speak to add variety, interest and color to your voice and what you are saying.

Both Henry Kissinger and Robert Dole speak in monotones. Their speech is completely devoid of inflection.

In "My Fair Lady", Henry Higgins used a xylophone to show Eliza Doolittle how to develop inflection. He first played the sentence below on the xylophone and then had Eliza imitate the pitches. It was the most direct way to bring inflection into her voice. You can do the same on the piano with any sentence. As you read the sentences, notice how the voice rises and falls.

kind come.
let
How of you to me

Once you get the idea, try using inflection with other sentences. It adds to your personal style, making you sound so much more interesting than if you say everything on one pitch.
