Our First Leadership Voice: Mom

At around seven months in the womb, we begin to hear.

And whose voice reaches us first?

Our mother’s.

Filtered through fluid, like listening through a wall of water, each time we hear it, our heartbeat hastens.

At a physiological level, we begin to understand:

This voice matters.

At birth, we take our first gasp of air and announce our entrance with an ear-piercing cry.

As if to say:

I am here! I have something to say!

And just like that, communication begins.

Your First Teacher

Your mother becomes your first voice teacher.

While babies have incredible hearing, they are especially attuned to higher frequencies. So what do caregivers do?

They adapt.

Scientists call it “Motherese.”
A high-pitched, melodic, slow, and exaggerated way of speaking: 

“Who’s a good Baaaay Beeee?” “Buh Buh Baaay Beeee.” 

It might sound simple—but it’s doing something profound.

This is how:

• Enunciation is learned
• Dialects are imprinted
• Communication is built

Through interaction: the back-and-forth between caregiver and child.

When You Think About It

The foundation of human communication is built on the female voice.

Then Something Changes

And this is where it gets interesting.

At puberty, biology shifts the voice:

• In females, estrogen keeps vocal cords shorter, thinner, and the larynx smaller and higher, resulting in a higher pitch
• In males, testosterone lengthens and thickens vocal cords, expands the chest and throat, and lowers the larynx—creating a deeper, more resonant voice

And with that shift… perception changes too.

Research consistently shows:

• Lower voices are perceived as more authoritative
• People with deeper voices are more likely to be promoted—and even elected
• They often earn more

Through evolution, biology, societal conditioning, and technological influences, we made a quiet but powerful association:

Lower pitch = leadership.

The Marginalization

The preference of low-pitch in leadership has had a negative effect on women:

Up to 80% of women report dissatisfaction with their voice feeling like something is off, lacking, or not quite right.

That shows up as:

• Voices held back in meetings
• Ideas left unsaid
• Leadership potential overlooked

At the highest levels, the scrutiny becomes public.

Women competing on the world stage—like Kamala Harris and Hillary Clinton—are critiqued not just for what they say, but how they sound… even how they laugh.

Meanwhile, no one’s writing think pieces about a man’s “tone problem.” No matter how rough around the edges it might be.

What We Lose

When voices are dismissed, we all lose.

• We lose ideas.
• We lose innovation.
• We lose the best person for the role.

And maybe most importantly—we lose alignment with something deeply human:

The very voice that taught us how to communicate in the first place.

What You Can Do (Start Small, Start Smart)

Let’s bring this out of theory and into practice.

Take a look at your meeting room.

• Can every voice be heard without strain?
• Or does someone with a quieter voice have to work twice as hard just to get airtime?

Because when someone has to push their voice:

• Pressure increases
• Pitch rises
• And perception shifts (“Why is she yelling?”)

And just like that, credibility can take a hit—for reasons that have nothing to do with the idea itself.

Better acoustics. Microphones. Intentional listening.

That’s not just a technical fix.
That’s Voice Equity in action.

Let’s Be Clear

The female voice is not a lesser version of a “leaderly” voice.

It’s the original blueprint for human communication.

It starts with lullabies.
It builds through connection.
It teaches us how to speak, listen, and understand.

It’s already powerful.

So Here’s the Shift

When we expand what leadership sounds like,
we make room for voices that have been there all along.
