Forging Voices and Faces: The Dangers of Audio and Video Fabrication
Technology companies including Google, Baidu, and Adobe have recently funded efforts to fabricate audio or video from samples of speech or fragments of footage. Startups including Voicery and Lyrebird have developed customizable human voices (built from audio recorded by professional voice actors) that can be programmed to say anything. These companies have also released do-it-yourself software that lets you synthesize your own voice (or someone else’s, with their permission) from a 1-minute recording.
And open-source tools to build such programs are available on Github.
