New Anthony Bourdain documentary includes artificial intelligence version of chef's voice

A new documentary about Anthony Bourdain, who died in 2018, includes an artificial intelligence version of the chef's voice, raising ethical concerns for some fans. 

"Roadrunner" director Morgan Neville said in an interview with The New Yorker that he used Bourdain's voice from several sources, including TV, radio and podcasts, to narrate the film. However, he wanted to use three quotes that there were no recordings of – one of them being a part where the "Parts Unknown" host reads an email he wrote.  Neville told the magazine he and his team compiled together about 12 hours worth of recordings and handed it over to a software company, which recreated his voice.
