A voice is multidimensional in that it carries words, emotion, energy, and identity. Some voices immediately draw us in with what they say and how they make us feel. Historically, voices from the American South have been associated with warmth and hospitality, which is why they’ve often been used in telephone marketing. They’re easy on the ear and create a sense of comfort. We experienced this with the late American President, Jimmy Carter. His gentle Southern drawl conveyed humility, compassion, and sincerity, qualities that shaped how the public perceived both the man and his message.

Great speakers across generations have shared a common trait: vocal resonance. It’s that deep, rich quality that seems to vibrate through the air and command attention—Martin Luther King Jr., James Earl Jones, Barack Obama, Oprah Winfrey, and Adolf Hitler, to name a few. The latter of which may seem offensive to add to this list. Yet, these voices do more than communicate—they move people to action. Therefore, matching intention with the desired outcome is a must.

I remember experiencing this firsthand as a young boy visiting the Texas State Capitol with my father, who was then a state attorney. That day, my dad introduced me to Congresswoman Barbara Jordan, who named me an honorary page. Her voice was unforgettable—deep, strong, and full of conviction. It was the first time I’d heard a woman speak with such unshakable authority. At least a woman outside of my family, all of whom carry unshakeable authority in their voices. I didn’t just hear Ms. Jordan’s voice—I felt it.

Years later, I attended the Broadway play Tea at Five, in which Kate Mulgrew portrayed Katharine Hepburn. In the play, Hepburn talks about how her voice teacher helped her cultivate the distinct tone we all associate with the actress. Her voice announced her presence even before seeing her on screen. Like Hepburn, many speakers, actors, and leaders alike intentionally shape their voices to reflect who they are and how they want to be remembered.

You can too!

We explored this in more depth in our earlier blog, “The Executive VOICE,” where we outlined five key tools every leader can use to strengthen their vocal presence. These tools—known collectively as Vocal Diversity—include:

• Pitch – the musical highs and lows that add emotion
  
• Speed – the pace that controls urgency and clarity
  
• Timbre – the texture or quality that makes your voice unique
  
• Volume – knowing when to command and when to soften
  
• Articulation – clarity in how your words are shaped and delivered
  

Monotone speaking quickly loses attention. By varying these elements, you create a voice that invites people to stay tuned in, whether you’re talking to direct reports, senior leadership, or an audience of thousands.

Your voice, when developed with intention, becomes one of your greatest leadership assets. Its power comes not from perfection, rather from sounding authentically you, while being confident, clear, and compelling.
