Train Like an Actor: Unlocking the Power of Your Voice for Clear, Confident Presentations

Have you ever listened to someone speak and thought—wait, what did they just say?

We’ve all been there. You lean in, furrow your brow, tilt your head like a confused puppy… but it doesn’t help. You still can’t quite catch the words. Maybe it was the muffled microphone, the too-fast delivery, or the speaker’s habit of blending words together like they’re running a verbal marathon.

If you’ve experienced this as a listener, here’s the uncomfortable question—could your audience be experiencing the same thing when you speak?

Your Voice: The Most Neglected Presentation Tool

Most presenters obsess over their slides. Fonts, data points, color schemes—check. But when it comes to how they actually sound when delivering their message, most leave it to chance. That’s a missed opportunity, especially for anyone speaking English as a second language (ESL) or those who’ve been told they “speak too fast” or “aren’t clear enough.”

Your voice is your delivery system. No matter how perfect your content is, if your audience can’t understand you, you’ve lost them.

This is where you can borrow a secret from professional actors.

What Actors Know That Most Presenters Don’t

Actors don’t step on stage or in front of a camera cold. They warm up their voices every time. Why? Because their careers depend on being heard and understood.

Actors use vocal warm-ups to improve:

• Pronunciation (saying sounds clearly and correctly)

• Articulation (shaping words crisply and cleanly)

• Breath control (so they don’t run out of air mid-sentence)

• Vocal variety (to avoid sounding robotic or flat)

  
  

And the good news? These same techniques work wonders for presenters.

In this excellent video, a voice coach shares simple exercises that professional actors use.

You don’t need to be preparing for Broadway to benefit from them—you just need to care about helping your audience understand your message.

Three Common Voice Mistakes (And How to Fix Them)

1. Mumbling or Slurring Words

Do you ever rush through words without really opening your mouth? Many people do, especially when nervous or speaking in a second language. Lazy mouth muscles lead to lazy pronunciation.

Fix it with: Lip trills (buzzing your lips like a motorboat) and tongue twisters to wake up your face and stretch your articulation muscles.

2. Speaking Too Fast

When adrenaline kicks in, your brain moves faster than your mouth. The result? You speed through your talk like you’re being timed.

Fix it with: Breathing exercises and marking natural pauses in your notes or slides to slow yourself down and give your audience time to process.

3. Monotone or Flat Delivery

Speaking in a flat, emotionless tone is the fastest way to lose your audience. People tune out when they don’t hear energy or variation.

Fix it with: Pitch and volume exercises—try going high, low, loud, and soft to unlock your natural vocal range.

Voice Training Techniques You Can Steal From Actors

Here are some practical exercises inspired by professional actor training:

• Lip Trills (a.k.a. the Motorboat Sound)

  Make a buzzing sound with your lips. It looks silly, but it loosens up your jaw and mouth muscles so your words come out cleaner.

• Tongue Twisters

  Classics like “Red leather, yellow leather” or “Unique New York” help sharpen your articulation. Start slow, exaggerate the sounds, and build up speed.

• Pitch and Volume Play

  Try reading a short sentence in different pitches and volumes. Feel the difference in energy when you go from whispering to booming. This helps you avoid monotone delivery.

• Breathing Control Practice

  Breathe deeply through your nose, expanding your belly, then speak while letting the air out slowly. This helps you avoid breathless sentences and improves control.

  
  

Four Quick Exercises to Add to Your Presentation Routine

1. Warm Up with Lip Trills

   Do this in the car on the way to work or before your meeting. It warms up your vocal muscles and wakes up your face.

2. Challenge Yourself with Tongue Twisters

   Make it a daily habit. Try it with your team or challenge a friend to see who can say them faster and clearly.

3. Record Yourself Reading Aloud

   Play it back. Are you easy to understand? Are you rushing? This is one of the fastest ways to catch unclear speech patterns you didn’t realize you had.

4. Experiment with Pitch and Pause

   Take a sentence like, “I’m excited to share this update with you,” and practice saying it with different pitch patterns and pauses. You’ll quickly notice what sounds more natural and engaging.

   
   

Make Your Voice Part of Your Preparation

Actors wouldn’t dream of performing without warming up their voice. Why should you?

The next time you’re preparing for a big presentation, don’t just rehearse your slides—rehearse your voice. Warm it up. Stretch it out. Play with it. Get comfortable using it as a tool to help you connect with your audience.

Because if actors can fill a theater with their voice, you can fill the boardroom—or the video call—with clarity, confidence, and energy.

So go ahead—train like an actor.
