Voice Actors For Big Mouth

Have you ever watched Big Mouth and thought, "How do they do that?" The voices behind those hilariously awkward pre-teens are a masterclass in pure, unfiltered chaos. It’s not just acting; it’s a joyful, ridiculous, and deeply human form of artistry. Let’s dive into the weird world of the voice actors who make puberty sound so darn funny.

The Magic of Vocal Transformation

You might not recognize Nick Kroll’s normal speaking voice, but you’ve definitely heard him as the hormone monsters Maurice and Maury. These characters are loud, impulsive, and utterly shameless. Kroll has explained that voicing them requires him to tap into his most unfiltered, childlike energy. It’s a reminder that sometimes our best selves are the ones we let get a little messy.

Then there’s John Mulaney as the anxiety-ridden Andrew Glouberman. Mulaney’s delivery is a masterpiece of frantic, high-pitched desperation. He makes Andrew’s constant embarrassment feel like a universal experience. Have you ever felt like the world is ending over a zit? Mulaney proves you’re not alone.

Voicing the Hormones Themselves

One of the show’s secret weapons is the actor for the Shame Wizard, David Thewlis. Yes, that David Thewlis—the intense actor from Harry Potter. Hearing him deliver lines about guilt and regret with such sincere seriousness is comedy gold. It teaches us that even our worst feelings can become something hilarious with the right perspective.

Don’t forget the women! Maya Rudolph voices the feisty and opinionated Hormone Monster Connie. She brings a level of maternal authority to a creature that lives for chaos. And let’s be honest, her voice makes you feel like you could handle any awkward conversation with a little more sass.

Why This Matters for Your Own Life

Here’s the surprising takeaway: these actors show us that embarrassment is a superpower. They don’t shy away from awkwardness. They lean into it, amplify it, and make it sing. You can try this yourself! Next time you feel flustered in a meeting or at a party, try using a funny voice to describe your situation. It breaks the tension instantly.

Voice acting also pushes you to be a better listener. To mimic a character, you have to absorb their rhythm, their pauses, and their quirks. That skill—really hearing someone—makes everyday conversations much richer. Plus, it’s just more fun to talk like a hormone monster than like a stressed-out adult.

How You Can Get Started

Believe it or not, you already have the tools. Your own voice is a unique instrument full of potential. Start by reading a children’s book out loud in different voices. Give the narrator a Southern drawl. Turn the villain into a sleepy British butler. The goal isn’t perfection—it’s play.

There are amazing online communities and even free apps for voice acting warm-ups. Try a simple one: say “Butterfly” in a growl. Then in a whisper. Then like a robot. It sounds silly, but it wakes up your vocal cords and your funny bone. You’ll find yourself laughing before you know it.

The Uplifting Takeaway

Here’s the truth: life is full of awkward, messy, and embarrassing moments—just like in Big Mouth. But the voice actors on that show remind us that we can choose how we sound in response to those moments. We can be the anxiety-ridden Andrew, or we can be the flamboyant, confident Hormone Monster Maurice. Both are valid, but one is way more fun.

So, go ahead. Tomorrow, walk into the grocery store and silently narrate your shopping list in a movie trailer voice. Or practice a friend’s catchphrase in the car. Big Mouth’s actors didn’t start as experts; they started by being willing to look a little silly. And that willingness is what makes life more colorful, more connected, and infinitely more funny. You have a voice. Use it wildly.
