Thread: Deep Fakes Are Here

1. What constitutes a deep fake?

While manipulation of digital files is nothing new, this breed of believable fakery is accomplished using computer programs that employ a form of artificial intelligence. An algorithm is trained to recognize patterns in actual audio or visual recordings of a particular person, a process known as deep learning. As with doctored images, a piece of content can be altered by swapping in a new element — such as someone else’s face or voice — and seamlessly joining the two. The manipulations are most misleading when combined with voice-cloning technology, which breaks down an audio recording into half-syllable chunks that can be reassembled into new words — the same method that’s used to create voice assistants like Apple’s Siri and Amazon’s Alexa.
