What began on stage as beatboxing in the early 2005 evolved into something much deeper: an exploration of how voice can move people, shape stories, and build unforgettable brand experiences.
Over the years, Rudi Rok has transformed his voice into a design tool - building emotional soundscapes, crafting sonic identities, and pushing the boundaries of what a single human voice can do. Today, he works at the intersection of creativity and strategy, where sound isn’t just heard - it’s felt.
As a creative director and voice artist, Rudi leads bold projects with global impact.
His work has been recognized by Cannes Lions, LIA, D&AD, and AdFest - not for the volume, but for the resonance it creates.
Every tone, every breath, every sound you hear is intentional. And it all begins with the most human instrument we have.
The most advanced sound design tool wasn’t invented. It was born.
— and it still beats AI at being human
Before dedicating his career to the power of voice, Rudi Rok spent years building brands from the ground up. In 2016, he founded Helsinking, a boutique ad agency where he directed, edited, shot, and shaped creative concepts across hundreds of commercial projects.
Through this hands-on experience, Rudi developed a deep and holistic understanding of branding - from visuals to storytelling to sound. It’s this background that makes him a uniquely valuable creative partner today: fully focused on human voice, but fluent in the bigger picture of brand identity.
RUDI ROK - HUMAN VOICE DESIGN SHOWREEL 2025
The human voice is the most expressive, versatile, and emotional sound design tool in existence.
In the age of AI, the human voice becomes premium.
For us, it’s more than just sound - it captures life, values, and a deep connection to something raw and real.
Our voice is not emulated. Not programmed. Not synthetic.
It’s something at the moment. Precise. Alive.
Over the last decade, I’ve built a creative process around the human voice.
Concept, voice, execution - all handled with the same level of detail, originality, and control you’d expect from a full production studio. Everything is crafted with intent. Every project is tailored. Every team, handpicked.
What I offer isn’t something you can download, imitate, scale, or prompt.
It’s singular. It’s strategic. It works.
In my studio everything is made with 100% human voice.
This is Human Voice Design.

Fiat 500E - Engine Sound
THE CREATIVE CHALLENGE
When Fiat introduced the all-electric 500e, they needed a sound that would meet EU regulations requiring electric vehicles to have an Acoustic Vehicle Alert System (AVAS). The sound not only had to ensure safety but also reflect the car’s playful and iconic character, making it stand out from the competition.
Nick Wood, CEO and Creative Director of Syn Music, approached Rudi Rok to tackle this challenge. The mission was to create a sound entirely from human voice—something truly unique that would match Fiat’s vision for the 500e.
THE SOLUTION
We saw this as a perfect opportunity to use Rudi’s talent as a voice artist to craft a one-of-a-kind engine sound. Working closely with Nick Wood and the Syn Music team, we began shaping the sound using only Rudi’s voice, ensuring it captured both the essence of the vehicle and the technical requirements for safety.
Our approach was rooted in creativity, using the warmth and imperfection of the human voice to bring life and character to the Fiat 500e. The result was an engine sound that feels not only functional but also human—giving the car an audio identity that is distinctive, lively, and memorable.
OUTCOME
The engine sound of the Fiat 500e stands out as a groundbreaking achievement in automotive sound design. Crafted entirely from human voice, it brings warmth, character, and creativity to a space typically dominated by synthetic sounds. This project demonstrates Rudi’s ability to deliver imaginative and human-centered solutions that resonate with both the brand and its audience.

Mountain Dew Radio Spot
A full gaming universe. One word. 100% human voice.
In collaboration with BBDO and SYN Music, Rudi Rok brought a groundbreaking sound design concept to life for Mountain Dew’s award-winning Play The Dew campaign - an audio-first creative that turned the brand’s name into a complete gaming soundscape. Every sound in the campaign was created using just one word: “Dew.” And every sound was made with one tool: the human voice.
Rudi’s task was to create an immersive first-person shooter (FPS) audio world for the campaign’s radio launch - without any instruments, libraries, or synthetic elements. Gunfire, helicopters, footsteps, explosions, zombie growls, fighter combat — all designed vocally, using variations of “Dew.”
This sonic foundation became the DNA of the entire campaign, influencing gameplay films, racing soundscapes, and even a TikTok-powered audio game where players shouted “Dew” to accelerate.
The Voice Behind the Impact
Rudi Rok’s role centered on concept development, vocal performance, and soundscape creation. Using advanced vocal techniques and a strategic layering process, he crafted a rich, high-intensity gaming world that felt both cinematic and playful. Each sound was expressive, emotionally resonant, and brand-ownable. Crafted for brand storytelling and audience immersion.
Strategic Insight
Instead of traditional partnerships or in-game branding, Mountain Dew used audio as the lead medium. The campaign proved that with a distinct idea, even a single word can become a full branding ecosystem — especially when performed by a one-of-a-kind voice artist.
Creative Outcome
The Play The Dew campaign captured the energy of gaming culture through a playful and disruptive use of voice. In a time where AI-generated content dominates, this campaign made human sound the differentiator - emotional, unpredictable, and unforgettable.
Rudi Rok’s human voice design was the core creative engine behind one of Mountain Dew’s most innovative campaigns to date.

Ensto - Sonic Logo
Ensto - a large international tech company, specializing in electricity distribution networks - went through a process of rebranding and refreshing their strategy and as a result, they created a new slogan: ”Better life. With electricity.”
They approached us as they wanted to create a sonic logo that would reflect this new brand promise and strategy. Their main values as a company include human centricity, creativity and excellence in execution. Having a sonic logo made entirely with human voice, enforced and brought even more value.
THE CREATIVE PROCESS
The vision for the sonic logo was to create an audible representation of a world transforming from the old age of loud noise and pollution, into the future - a more harmonious, clean and natural world. Here’s the journey, how we brought the mnemonic to life using human voice:
This premise took us to the first version of the sonic logo, which was a very tangible take on this vision:
VERSION 1/5
We felt that this version was too concrete and rough…
VERSION 2/5
..so we added in a harmony, to take us through the transformation from the past to the future.
This was a good step forward, and we decided to play with the idea of going towards a more abstract approach.
Each of the letters E-N-S-T-O got their own note, and these notes created a melody that was the base for the third version of the logo. We also decided to bring in electricity as an separate element:
VERSION 3/5
However, having the sound of electricity in the beginning of the logo felt like too much…
VERSION 4/5
…so we made a version without it:
This felt like the right direction to go, and to finish it up…
…we brought back in the harmony as an element that acted as a representation of the world transforming and moving forward to a better life:
VERSION 5/5
“Better life. With electricity”

Slotherhouse - Character Voice
In Slotherhouse, a 2023 comedy-horror feature film, Rudi Rok was tasked with voicing the film’s main antagonist: a killer sloth named Alpha. The character needed to shift between being both charmingly cute and terrifyingly dangerous, and Rudi’s expertise in voice acting brought this unique blend to life.
THE CREATIVE CHALLENGE
The brief was simple yet demanding—Alpha needed a voice that could carry the emotional range of a villain while still sounding like an animal. Rudi was asked to create a vocal performance that would highlight Alpha’s dual nature, switching seamlessly between affectionate and menacing. Drawing on his background in sound design and voice acting, Rudi researched real sloth sounds and expanded them into something both recognizable and emotionally expressive.
THE PROCESS
Rudi recorded Alpha’s voice in Finland with his trusted local team, while the director and producers participated remotely from the U.S. The sessions were a highly collaborative process, with Rudi physically embodying the character’s slow, deliberate movements during recording. This physicality was crucial in helping him capture the sloth’s personality and ensure that the voice matched the on-screen action.
The character’s journey—from a seemingly lovable pet to a feared predator—required careful attention to detail in the voice performance. The team’s reaction after each session reflected the success of Rudi’s work, with Alpha becoming an integral part of the film’s dark, comedic tone.
OUTCOME
Rudi’s voice work was central to Alpha’s character, making the sloth both endearing and frightening. The film, released in August 2023, gained attention for its quirky premise, with Rudi’s performance standing out as a key element in bringing the character to life. His voice acting helped define the balance between humor and horror that made Slotherhouse memorable.
