Machine Voices Getting More Human

Episode 1813 (02:40)

Bourdain

Companies like Amazon and Google are doing to great lengths to make their assistant voices sound more human. Even going so far as to bring celebrities in to record random sentences and then use artificial intelligence to fill in the gaps. Known as "prosody," the technique is starting to put voiceover artists out of work since a computer can fake recorded sounds that are indistinguishable now from the human voice.

The technique has also been seeded down into documentaries, as filmmakers are using prosody to create audio files based on writings, to create statements that people have never made. This happened in the new Anthony Bourdain documentary. And Leo says that's concerning.
