Flat, monotone delivery doesn’t grab attention—and it doesn’t inspire. To sound more compelling when presenting, add the three E’s: Energy, Enthusiasm, and Expression. Many professionals fall into the trap of sounding flat, thinking it makes them appear more controlled or serious. But the opposite is true—energy sells your message.

How to Add Energy

  • Vary your pace: Speed up, slow down, and pause for effect.
  • Get physically fit: Physical energy fuels vocal energy.
  • Deepen your breathing: Nasal or shallow voices lack power. Practice breathing from the diaphragm to increase volume and clarity. (Source: Harvard Health)

How to Show Enthusiasm

  • Believe your message matters: If you sound like you care, others will too.
  • Speak to their WIIFM: That’s “What’s In It For Me?” Tailor your message so it resonates with your listeners’ goals.
  • Mix things up: Change location, tone, or volume to keep things interesting.

How to Add Expression

  • Use your face: Your facial muscles help shape vocal tone. Practice in front of a mirror.
  • Smile more often: A smile changes how your voice sounds—brighter, warmer, and more engaging.
  • Watch your mouth: Don’t let your expression sag; it drags your vocal tone down with it.

Real-World Example

One senior executive I worked with had great content but a flat tone. Through vocal exercises and breathing work, she added dynamic range. In her next keynote, her feedback included, “She was inspiring and clear.” Tone made the difference.

Expert Insight

According to UCLA’s Dr. Albert Mehrabian, when it comes to conveying emotion, 38% of communication is vocal—your tone, pitch, and pace. (Mehrabian, 1971) Your tone matters just as much as your words, if not more.

“Don’t just speak to inform—speak to inspire. Tone carries intention.” — Sarah M. Khaled
