“Ladies and gentlemen, welcome to the ultimate showdown of creativity and technology—’The Ads Battle: Human vs. AI.”

In the digital arena tonight, the contest is straightforward yet groundbreaking. Two identical video ads step into the spotlight, differentiated only by the voice that brings them to life—one human, one AI.

The victor will be decided based on three critical KPI’s:

1) Conversions: the ultimate measure of success

2) Click-Through Rate (CTR), evaluating the immediate appeal

3)Cost Per Click (CPC), assessing cost-effectiveness

The Contenders

“In the red corner, armed with HeyGen technology, we have the AI-voiced ad generated by HeyGen, a solid platform for creating content using AI—with many innovative, customizable features (ex: modify the pitch in the voice).” HeyGen is very well known for its solid record of top-performing AI creatives!

“In the blue corner!!, we find Benoit, a UGC black belt with a sometimes wild imagination and a very pronounced French Canadian accent. You can’t find better for an imperfect voice! Still, Benoit has an impressive history with UGC creatives, handling campaigns that have rolled through millions in ad spend.

“In a stunning first-round knockout, the human voice clinched victory, demonstrating that genuine connection can’t be underestimated. The AI-generated voice, despite its technological edge, fell short where it mattered most: it cost over double per click ($1 vs. 40 cents) and struggled to match the human voice’s click-through rate. But the deciding blow was delivered on conversions—the AI voice failed to secure any.
