An AI can replace what a world leader said in his video-taped speech. This will end well. Not.
Researchers have crafted algorithms that can blend an audio recording of someone talking with a video of them saying something else entirely – and create a new convincing lip-synched video with the replacement sound.
In other words, the resulting video carries the injected audio, rather than its original sound, and the frames are manipulated so that the speaker's face and mouth movements match the new audio.
You can be forgiven for seeing this as a vital stepping stone to creating the ultimate fake news – highly believable forged video evidence. Imagine taking a clip of someone important speaking at a private event, and using the aforementioned software to dub in a completely new script, voiced by a skilled impersonator or generated by another AI such as Lyrebird, and then distributing that fraudulent footage.
