• The system takes an image of a person as well as an audio clip to create a video
• It identifies facial features in photos using algorithms that recognize the face
• As audio plays, it manipulates the mouth so it looks like the person is speaking
• With improvement, the researchers say the AI could make fake videos seem real
• The system could eventually render video evidence unreliable in court cases

Researchers have developed an artificial intelligence system that can put words right into people's mouths.
It takes an image of a person as well as an audio clip, using them to create a video of a person speaking that audio.
While the system is still rough and not realistic looking, the researchers claim the software could soon make fake videos that seem real

But WAIT...There's MORE!

Artificial intelligence is making human speech as malleable and replicable as pixels. Today, a Canadian AI startup named Lyrebird unveiled its first product: a set of algorithms the company claims can clone anyone’s voice by listening to just a single minute of sample audio.

A few years ago this would have been impossible, but the analytic prowess of machine learning has proven to be a perfect fit for the idiosyncrasies of human speech. Using artificial intelligence, companies like Google have been able to create incredibly life-like synthesized voices, while Adobe has unveiled its own prototype software called Project VoCo that can edit human speech like Photoshop tweaks digital images.

But while Project VoCo requires at least 20 minutes of sample audio before it can mimic a voice, Lyrebird cuts this requirements down to just 60 seconds. The results certainly aren’t indistinguishable from human speech, but they’re impressive all the same, and will no doubt improve over time. Below you can hear the synthesized voices of Donald Trump, Barack Obama, and Hillary Clinton discussing the startup:
