Research shows that consistency in tone is extremely persuasive. People who don’t get shaken up and maintain a smooth approach have a natural advantage.
Stuttering, long pauses, pitch of the voice going up and down… none of these inspire confidence. Avoid emotional variability in how you carry yourself when presenting. A narrow tonal range conveys a high degree of control and certainty.
That said, this is not the best approach for all scenarios.
