Speak With Energy Without Sounding Fake
Forced enthusiasm fails because listeners can hear where energy comes from.
One skill: Producing energy from meaning
You’ve been told to “bring more energy”, so you tried, and heard yourself turn into a game-show host. It felt fake because it was: you added energy as a coat of paint on top of the words. Real vocal energy isn’t added. It leaks, from a body that currently cares about what it’s saying. Which means the fix isn’t acting. It’s plumbing.
Listeners hear the body, not the effort
The voice broadcasts physiology whether you like it or not. Victoria Tartter’s experiments showed listeners can reliably hear a smile they cannot see, smiling reshapes the vocal tract, raising the frequencies of the sound itself. The same transparency cuts both ways: arousal, boredom and effort all print onto the signal. That’s why manufactured enthusiasm registers as wrong, the words say excited while the body underneath says “performing”.
So the honest route to energy is to change the body’s state, not the voice’s costume. Alison Wood Brooks’ reappraisal work gives the lever: arousal you’d call nerves relabels cleanly as excitement, because it’s the same physiology. Nerves before speaking aren’t the enemy of energy, they’re unrefined fuel for it.
Three honest fuel sources
- Find the sentence you actually care about. Every topic has one point you’d defend at dinner. Start your preparation there: energy radiates outward from a stake, and listeners hear which sentence it is.
- Convert the nerves. Say “I’m excited” and let the arousal drive pace and pitch instead of suppressing it into a careful flat voice. Suppressed nerves read as low energy; converted nerves read as presence.
- Physically smile at the right line. Not throughout: at the one line that earns it. The listener hears the smile arrive, which lands as warmth precisely because it’s local and true.
- Mistake to avoid: uniform intensity. Energy that never varies is another monotone. Peaks need valleys; calm sentences are what make the alive ones audible.
✗ Painted on
“EVERY sentence is AMAZING and I’m SO excited about ALL of it!!”
✓ Leaking through
“Most of this is routine. But one number stopped me, ”
“and honestly, I’m still thinking about it.”
Your turn
The stake hunt
Take any dry topic you have to present, a status update works perfectly.
- Ask: what here would I argue about if someone got it wrong? Write that sentence down.
- Speak the update for 45 seconds, ordinary voice, letting only that one sentence carry your actual opinion.
- Notice you didn’t “add” energy anywhere, yet the update has a pulse now.
Practice it for real
The gap between felt and transmitted energy is exactly what a recording exposes.
- Record the same 60-second answer twice: once flat on purpose, once after naming your stake and converting the nerves.
- Play both replays back to back: hear where take two moves and take one doesn’t.
- Keep the second take’s setting; that’s your energized-but-yours voice.
Key takeaways
- The voice transmits body state: listeners literally hear smiles, and hear performance too.
- Energy can’t be painted on; it leaks from a stake you actually hold. Find that sentence first.
- Nerves are unconverted energy: “I’m excited” routes the same arousal into presence.
- Vary the intensity: uniform enthusiasm is just monotone at a higher altitude.
