An aspect of artificial intelligence that’s sometimes overlooked is just how good it is at creating fake audio and video that’s difficult to distinguish from reality. The advent of Photoshop got us doubting our eyes, but what happens when we can’t rely on our other senses?

The latest example of AI’s audiovisual magic comes from the University of Washington, where researchers have created a new tool that takes audio files, converts them into realistic mouth movements, and then grafts those movements onto existing video. The end-result is a video of someone saying something they didn’t. (Not at the time, anyway.) It’s a confusing process to understand by just reading about it, so take a look at the video below:


You can see two side-by-side clips of Barack Obama. The one on the left is the source for the audio, and the one on the right is from a completely different speech, with the researchers’ algorithms use to graft new mouth shapes onto the footage. The resulting video isn’t perfect (Obama’s mouth movements are a little blurry — a common problem with AI-generated imagery) but overall it’s pretty convincing.

The researchers said they used Obama as a test subject for this work because high-quality video footage of the former president is plentiful, which makes training the neural networks easier. Seventeen hours of footage were needed as data to track and replicate his mouth movements, researcher Ira Kemelmacher told The Verge over email, but in future this training constraint could be reduced to just an hour.

THE RESEARCHERS SAY THEIR TECH COULD BE USED TO IMPROVE SKYPE CALLS
The team behind the work say they hope it could be used to improve video chat tools like Skype. Users could collect footage of themselves speaking, use to train the software, and then when they need to talk to someone, video on their side would be generated automatically using just their voice. This would help in situations where someone’s internet connection is shaky, or if they’re trying to save mobile data.

Of course, there’s also the worry that tools like this can and will be used to generate misleading video footage — the sort of stuff that would give some real heft to the term “fake news.” Combine a tool like this with technology that can recreate anyone’s voice using just a few minutes of sample audio and you’d be forgiven for thinking there are scary times ahead. Similar research has been able to change someone’s facial expression in real-time; create 3D models of faces from a few photographs; and more.

The team from the University of Washington is understandably keen to distance themselves from these sorts of uses, and make it clear they only trained their neural nets on Obama’s voice and video. (“You can’t just take anyone’s voice and turn it into an Obama video,” said professor Steve Seitz in a press release. “We very consciously decided against going down the path of putting other people’s words into someone’s mouth.”) But in theory, this tech could be used to map anyone’s voice onto anyone’s face, will everyone be so scrupulous if the technology becomes widespread?

Don't tell me that's what they're using for buhari. But why is no credible source saying anything about this.

God bless d op of this thread. Exact situation of Naija presidency. Watch the last presidential speech and see for yourself, d speech is just a baddest DOCTORED CLIP. I come in peace

The technology exists and it's called "Deep fakes".

Some dodgy p0rn sites use it by superimposing faces of popular celebrities on their p0rn flicks.

Google : Deep fakes

That's why they can't do a live broadcast.

They last address they created was done days prior as it takes hundreds of hours to make the video realistic and so that was why the AI rendering broadcast did not speak on the Lekki massacre which occurred less than 48hrs before the broadcast.

Now that makes sense

GamalNasser:


Now that makes sense

And also consider that the presidency only reacted to the Lekki massacre two days after the AI broadcast via a press statement released by the media aides in Aso Rock.

Posterity will judge anyone, group or cabal that is playing tiki taka with the affairs of over 200 million Nigerians if this be true.

The delusional people from poto.poto region are at it again.

Their photoshop photos did not work, they are bringing stale news again

At this juncture Nigerians need to demand a live broadcast from the president.

Lol.

That will never happen.

Lol. Did you say "tiki taka"?

Buhari's fulani terrorist regime will soon be the reference point for the study of greatest scams of the century.
Nigerians must not allow these murderers get away with high treason. Bringing an Impostor to rule as president of a country is treason of the highest order!

not surprised at your defence of this evil and clandestine power drunk cabals. How much were you paid?
Buhari died in London, it's not something you can hide. This is not nigeria where you do your abracadabra. Come to London and say this and your stupidity will be slapped with reality.

Watch his forehead

It's very unfortunate how educated illiterates are abusing knowledge. That's why I always advocate 70% science and technology enrolment for all secondary schools in Nigeria.
Only ignorant will keep suspecting that PMB is either cloned, dead or govt use AI to dupe citizens. Some p are in hurry call others illiterates but they're more illiterate in their conscience.
PBM went to many international trips with all PDP governors in his first tenure, many PDP governors go to him when there is need, he went to round the country for 2019 campaign, 3 weeks back he had meeting with Adeboye, he always hold FEC meetings with ministers and among all these people many of them don't like him and still nobody among his enemies has come out to prove to u that he's not alive!
Mtcheww!!!

You don't need all these useless grammar.
A simple live media chat will settle this case.
Buhari dead in 2017 and we have been echoing it.
Only a fraudstar or an ignoramous will say otherwise.

exactly and he needs to do a press briefing with journalist.

Yet he could speak on the staff of office that was stolen at the Oba of Lagos' Palace a day after the Lekki shooting?!

Omenka, why are these guys so dull?
