Why Your Voice Feels Tight Under Pressure.
“Just take a deep breath.”
It’s the go-to advice before a big meeting, high-stakes pitch, or any moment where your voice needs to deliver. Well-meaning, no doubt. But if your chest is already tight and your thoughts are moving too fast to catch, that advice can feel more like a taunt than a solution.
This post is about what’s really going on in those moments, and what you can do that actually works.
The moment your voice disappears
A client once wrote to me before we’d even had our first session:
“My throat tightens, my chest is tight, my belly isn’t breathing at all.
I try to relax into it, my voice deepens… then it pitches up again.
I’m going to be a tough nut to crack.”
They weren’t. What they were experiencing was something I see all the time. The voice gives way before the words have even had a chance to arrive. Not because of lack of skill or preparation. But because of how the body responds to pressure.
It often starts with a shift that’s nearly invisible, except to the speaker. A subtle change in breath. Tension creeping in unnoticed. The physical effects of being placed on the spot.
Why “take a deep breath” doesn’t help
When you feel under scrutiny, delivering bad news, pitching an idea, or simply speaking up in a room full of senior people, your body activates its threat response.
This is the sympathetic nervous system at work. Fight, flight, or freeze. The chest tightens. The breath shortens. The pitch rises or vanishes altogether. You might feel like your voice is about to crack, or worse, disappear entirely.
And when someone tells you to “just breathe,” what you’re often doing is pulling in more air on top of the tension. It’s the exhale, not the inhale, that restores calm. That’s what engages the parasympathetic system, the part of you designed to slow down and reset.

The vagus nerve and the power of the outbreath
The vagus nerve is the star of this show. It plays a major role in your parasympathetic nervous system, governing the body’s ability to return to safety after stress.
When you slow and soften your exhale, you stimulate this nerve. That sends a clear message to your brain. We’re safe now. This isn’t just biology. It’s a practical tool for anyone whose work depends on their voice.
This is why sighing, humming, or speaking with a longer outbreath can shift your state within seconds. These aren’t habits to unlearn. They’re skills to deepen.
The breathing reset I teach clients
Here’s one of the first techniques I teach in my coaching sessions. A simple way to release tension and restore vocal ease.
Sit upright or lie down in semi-supine (knees bent, head supported).
Inhale gently through your nose. Let the belly expand without forcing it.
Exhale with a soft hum.
Feel the resonance in your face, chest, or lips.
Repeat for three to five breaths.
This does more than calm you down. It primes your vocal folds, centres your pitch, and gives you back a sense of control, without pushing.
Still feeling tight? Try the Cyclic Sigh
There’s another technique, shown in Stanford-led studies to reduce anxiety even more effectively than box breathing. It’s called the cyclic sigh.
Here’s how:
Inhale deeply through your nose
Take a second, smaller breath at the top
Exhale slowly and fully through the mouth with a sigh
This double inhale helps flush carbon dioxide, regulate heart rate, and signal to your nervous system that the threat has passed. It’s simple, quick, and incredibly useful before stepping into any pressure-filled space.
Your voice doesn’t need control. It needs safety.
What most clients discover isn’t just a more resonant, confident sound. It’s this.
“I don’t need to fight my voice. I need to support it.”
You can plan your message down to the last bullet point. But if your body still thinks you’re under threat, your voice will falter. Not because you’re weak. But because you’re wired for survival.
Through the Cannon Method, I work with professionals to develop voice, confidence, and presence. But it all starts here. With breath. And with the ability to find calm when it matters most.
