ROBOTS RUN THE SHOW AS SWISS RADIO TESTS AI VOICES FOR A DAY

The voices sound like well-known personalities, the music features trendy dance beats and hip-hop syncopations, and the jokes and laughter are contagious.

But listeners of an offbeat Swiss public radio station repeatedly got the message: Today's programming is brought to you by Artificial Intelligence.

Three months in the making, the French-language station Couleur 3 (Color 3) is touting a one-day experiment using cloned voices of five real, human presenters in what managers claim is a world-first and never-aired-before music composed almost entirely by computers, not people. From 6 a.m. to 7 p.m., the station said, AI controlled its airwaves. Every 20 minutes, listeners got a reminder.

With an eerie, Sci-Fi movie-like track whirring in the background, a soothing, raspy female voice said: “AI is taking your favorite radio by storm.”

“For 13 hours, our digital alter egos have taken the reins, broadcasting their voices and their messages across the airwaves, without mercy or respite,” the voice said, at times almost taunting listeners. “The boundaries between human and machine have been blurred, and it’s up to you to unravel what’s real and what’s fake.”
