one of the most chilling examples of what fake news could become is deep fa kes, what fake news could become is deep fakes, the term given to artificial intelligence techniques that could swa p intelligence techniques that could swap people's faces in videos, seemingly seamlessly putting them into situations that never happened. we first covered the phenomenon earlier in the year when a user—friendly application made the technique easy and freely available online. we all share the same home. it seems the ai genie is out of the body. -- bottle. the doors that have been open to me are not open to a lot of kids these days. it was making an impact on real news but you can imagine the applications if we cannot tell what is real. new tools developed by media forensics

projects claim to be able to automatically spot forgeries, and when big give away? they rarely blink. another potential giveaway is to look for signs of life, literally. subtle changes in skin tone invisible to the human eye that can reveal a human pulse. currently, deep takes over those cannot consistently replicate these su btleties consistently replicate these subtleties but as the technique develops, how long will that last? in the future of this technology has some murky possibilities, but we are starting to see some genuinely useful applications of it as well. yes there is definitely a dark side to fa ke yes there is definitely a dark side to fake greek, but their are also some exciting possibilities. we have put a new algorithm to the test here at the bbc, with newsreader matthew. today he is presenting, well, his own news, and marling which is that

doubted understands how the mouth of both the voice actor and matthew agnew, the software can switch these over, manipulating matthew's lips to read the words. this is the brainchild of a london—based sta rtu p, brainchild of a london—based startup, a company dreaming of making affordable hollywood type special effects available to the masses. although we tested it here ina new setting, it currently takes a whole day to create a digital model of a person. of course, the aim is for this dubbing to be possible on any video, regardless of how it's been filmed. although in a world where that becomes simpler, even the company itself can recognise the implications. so regards to trust and videos and photos and what's going to happen in this sort of space, i think photoshop was released in 1990. and since then, it has become very easy to edit images, you can remove objects, you can edit the background, you can do all these things
7:51 pm
that is done to most of the images that you view on the internet or in magazines today, right? the same thing is going to happen to video, i am convinced. i think humans will adapt as they'd adapted to the fact that, just like we don't take photos at face value, we can't take videos at face value, necessarily. so while the possibilities are exciting, we mayjust grow a little bit more suspicious of everything we watch. i'm using some technology that we first saw a few months ago — a speech synthesis system by lyrebird ai. just by listening to a few audio samples of someone talking, it can reproduce their voice digitally. like this. i am donald trump and i think that my digital voice is quite impressive. the lyrebird ai has been trained on many, many voices and it's taught itself what makes each voice different.
7:52 pm
now, that means that you don't have to record every phoneme, every single sound that your voice can make, because amazingly, it's found a more efficient way of sounding like you. the kind of algorithms we are using, it's something called deep learning or neural networks. and something that makes these kind of algorithms special is that you don't need to give them specific things to look for. and so, this dna of the voice, we know that you are able to synthesise new voices based on this and they will sound like the original voices, but we don't really know and so, it's a bit of a black box. but now, i'm using a prototype
7:53 pm
of version two, which has been trained using spanish voices. and this is the result. is this notjust the same as taking what i'm saying, turning it into text, and then putting it through an online translation tool and then getting the resulting text and putting it through lyrebird? so not exactly because, for instance, there are some words in spanish, the strong ‘r', that are not common in some other different languages. and so we could make you pronounce that sound, in your voice, even if you were not able to pronounce it before. why have you added this translation? so imagine if we could do movie dubbing automatically. if you have a course on mexican cooking, you could have it spoken in english or in italian or many other different languages on the same time as they are being released. lyrebird has already used its tech for good, banking the voices of those with motor neurone disease
7:54 pm
so they can still use their voice after they lose their ability to speak. what motivates you? i want to make my best effort into preventing that this kind of technology is misused or is used for other — or some people or it's used to steal the identities of people or to create political instability. do you think it may be possible to deploy deep learning in your network's artificial intelligence to be able to spot the fakes? definitely. and this is something we are working internally as one of the potential preventative measures of this technology. however, i think that the problem with this is that, long—term, is that the generated and the real will be basically impossible to distinguish one from each other. and so, that's why i believe that the solution, the ultimate solution to this kind of issue,
7:55 pm
is educating the public and letting them be suspicious of the media. it's 100 years since the end of the first world war, which makes this remembrance sunday an even more poignant and special day. one of the many commemorations taking place around commonwealth nations is being tested here, at the royal chelsea hospital, a retirement home for british army veterans. it's called nothing to be written, and it's an immersive vr experience based around sending and receiving of the so—called field postcards that soldiers wrote during the great war. it has sort of parallels to text messages that people can send now. that thing where there isn't a lot of message that you can put into it, you can't tell the stories,
7:56 pm
but it's just a connection to say "i'm ok, i'm thinking of you." and i thought that was really beautiful. a century after the supposed ‘war to end all wars,‘ this is a highly emotive insight into what it was like both at home and in the trenches. there are no visuals here of the brutality of war — these guys have already seen it too much of that. absolutely incredible. and it feels cold. the sun has come out, right? this is absolutely amazing. what i liked about wearing these during this session is that i was looking up at the sky and the colours of the sky. i thought that was brilliant. can i take my headset off? yeah. right. mmm. that was so realistic.
7:57 pm
you were there in the trenches. hmm. what they did is what they wanted to do, and that is to protect the country. many of them lost their lives. and i hope it has gone to people now these days what it was all about. very emotional. because i was with them. tonight will be one of the cooler nights and what will the overall quite a mild week once again. tonight, lots of showers across
