A distinct pattern surfaced as this year's Cannes Lions Audio & Radio jury room debated heavy contenders for the industry's top prizes. When it came to AI-driven work, campaigns that used the tech to cut costs or scale production often fell flat. The entries that won prioritized human connection over efficiency. The winning work skipped the generic AI slop shortcut, reflecting a practical industry pattern: the strongest audio campaigns are built through hybrid collaboration.
Edu Luke is the Founder and Sound Branding Creative at HEFTY Music & Sound, a São Paulo studio he's run for 11 years. He grew up inside a family of professional musicians and approaches his work as what he calls a "sound actor," adapting the studio's output to the emotional register of each campaign. HEFTY has earned 71 Cannes Lions, including six Grand Prix, alongside a 2025 Latin Grammy nomination. Luke served as a 2026 Cannes Lions Audio & Radio juror, an assignment that gave him a close view of the industry's current thinking on which uses of AI strengthen the work.
"Right now, there is this grey zone. We have clients in many countries, and each region has its own view of what is possible, what is prohibited and how AI cloning should be used," Luke says. The absence of a shared rulebook shows up inside the industry's judging rooms as well. Live debate is how the 2026 jury surfaced Hyundai's Coquí Alarmed campaign as an Audio Grand Prix winner after it initially went overlooked on the shortlist. "We were discussing big ideas for big markets and, of course, disagreeing in a healthy, respectful way. That's the beauty of live judging," notes Luke. "Online, you don't have the chance to spend time and debate the work. In-person deliberation is a much fairer way to judge."
The same demand for depth exposed where AI-centric entries fell short. Several campaigns that had looked promising on the shortlist didn't hold up when the jury pressed on how the finished work would land emotionally. Two entries in the same category made the point clearly for Luke's team. "One idea was based on parents recording their voices to build a free library of stories," Luke explains. "That was deeply human, and it was far more powerful than a competing idea that simply launched an app to generate custom AI stories for users. The AI concept looked good on paper, but once we heard the final execution and really listened to see how it feels, of course, we were not going to award it because it was a disconnecting factor for sure."
The same principle showed up in categories where the creative team has to do most of the emotional heavy lifting. Luke points to the Gold-winning campaign Searching for Birds on Wires as an example of what happens when a team commits to that emotional depth in a category where audiences have no pre-built affinity for the brand. "Helping an electric power company is incredibly challenging because nobody wakes up excited about paying their bills," notes Luke. "You can only touch people's hearts and shift their perception of that brand with a deeply sensitive project. An AI-generated playlist on Spotify isn't going to make you connect with your consumer in a proper way. That was the biggest lesson there, even for myself and my team."
The pattern the jury saw in categories where AI fell short shows up inside Luke's own studio, where AI has settled into a role as a starting input, useful for prototyping and accelerating early stages while the final deliverable still gets carried by human judgment. Luke frames the discipline his team practices as a mission alignment problem, where the wrong use of AI compromises the emotional work brands are paying for. "Yes, we have to embrace AI as a technology that is here to help us, but we cannot let it become a distraction or a lazy shortcut," he advises. "Our mission is not saving costs by any means for the sake of saving costs. It is to touch people's hearts and make those brands communicate with who they need to."
The mission-alignment framing shows up in Luke's response to a genre of AI marketing content that has become common on industry feeds. Luke's team has tested enough of the underlying tools to know where the pitch stops matching reality, and the gap only widens once the work has to move through the review process and craft standards that a real client engagement requires. "The industry is starting to question all those viral AI videos on LinkedIn where creators boast about making a film in two hours for just two dollars. Everyone has tried those tools by now and realized the technology simply isn't there yet, we have a long way to go," says Luke. "When you have a real mission with a real approval chain, you have a big process to make things happen."
Inside Luke's own studio, AI has become an operational accelerant on the parts of the workflow that don't require creative judgment. His team uses it to prototype songs, clean up poorly recorded audio, and generate scratch voiceovers that keep client approvals moving faster than the traditional cycle would allow. On the business side, Luke leans on operational and legal tools to absorb the administrative work that used to slow the studio down. AI takes the tasks that do not need human sensibility, leaving Luke's team free to spend their hours on the parts of the work that human collaboration still owns. "The smart people are the ones that are aiming for hybrid collaboration and see AI as a tool to help humans do their best," Luke notes.
The one part of the AI question Luke is watching most closely is voice cloning, which functions as both a daily compliance problem for his studio and a heritage concern for the community of professional musicians he grew up around. Now, agencies are trying to work around state-level legislation on AI-generated performers while labels, composers, and platforms fight in court over the underlying licensing framework. Luke's argument is that the sector needs a settled position from the parties with the leverage to set one, regardless of which side wins the specifics. "Behind it, there's a lot of legal stuff. There's Big Tech doing their lobbying, and also the artists, the composers, on the other side," he concludes. "Next year, I'd like to see this clearly. For the good or the bad, hopefully the best, but for once have it written in stone."
