this is bbc news, the headlines: the un secretary general calls for an immediate ceasefire in sudan after nearly 70 people were killed in fighting between rival military factions. the leader of the nurses�* union says they're prepared to continue strikes in england right up to christmas unless the government puts more money on the table for a pay deal. the chief minister of the indian state of uttar pradesh appeals for calm after a former politician convicted of kidnapping is shot dead live on tv along with his brother. the building of all new smart motorways in england

is being cancelled over safety concerns and costs, this includes 11 already on pause and three set for construction. now it is time for click. this week: phone: sit up straight! the phones are taking charge, the robots are doing the cooking and the humans are... well, just lying around, really. we're in korea to visit the country's best—known exports. we're in ukraine to meet the hacktivists trying to help win the war. and if you've ever

wondered where the sounds in your phone come from, prepare to be... underwhelmed. smacks lips. low-pitched groan. that's your new ringtone right there. jaunty music plays. you know how it is. you're wandering through a bustling capital city and you fancy a coffee, so you call up an app, select your drink — ooh, iced banana latte, don't mind if i do — and send the order through so the barista can make it in advance. and the barista's name is b;eat. hello, b;eat. well, right now, i'm struggling to see the point of him. all he's done is put the cup on to the machine. i'm in seoul, south korea, for the first time since the pandemic, and i'm looking for signs of this hyper—advanced nation's continued push into the future.

machine speaks korean. of which my banana latte is a small sign. see, in 2020, the government at the time introduced a new policy called untact — that's the opposite of contact — which aimed to promote economic growth by automating parts of society and removing human contact at the same time. here's a mobile shop where you can buy phones and sign contracts without dealing with a real person. and here's how you get airport information these days. robot: please give me the airline information. | i will show you where it is. please wear a face mask for the health of the people around you. it's no surprise this policy was given a boost by covid, when we were all encouraged not to touch anything or be near anyone. mind you, i'm not sure it explains why my chicken was fried by a robot yesterday. how do you want yours done? as one of the most high—tech

countries on earth, south korea is in a prime place to make these changes. with nearly 100% of under—40s online, they love their technology here. and untact was not the first government policy to try and help this nation's rise. in fact, it was a government push towards industry and, later, high—tech industry that's got it to where it is today. in the last 60 years, this country has completely reinvented itself, going from one of the world's poorest nations to an industrial and technological powerhouse. a huge part of its success is down to the massive family—run businesses called chaebols that tower over seoul. you'll have heard of a few of them, i'm sure. there's lg, arguably the country's king of home goods and,

of course, those bendy tvs. hyundai makes everything from electric cars and robo—taxis to one of the world's biggest floating cranes, capable of lifting 10,000 tonnes. and sk group has a firm grip on telecoms, 5g, chips and semiconductors. but all of these names are dwarfed by the country's best—known brand, samsung. its h0 is a massive campus in the city of suwon and it's certainly on a par with those of tech companies that i've seen elsewhere in terms of scale — although not every tech campus i've been to has a climbing wall. but these days, you do need to give your staff the freedom to work the way they want, and that includes new ways to achieve new heights.

c—lab stands for "creative lab". all the samsung employees can submit their own idea. once they are selected, they are excused from their assigned work and focus only on developing their ideas. many big tech firms have seen the benefit of setting up in—house accelerators and since c—lab started in 2012, it's supported over 500 start—ups. every year, 30—a0 projects are chosen, and lee dayoung's was one of them — although she did have the help of a friend. hey, say hi. "hi." piloto is a child's smartphone companion and maybe a guardian. a friendly face with a cheeky sense of humour who meets kids on their own level. normally, kids like to talk about toileting. yeah, i know — i've got two, they love it. that's the reason why we put that scenario.

today, parents are using parental control apps, which means controlling the screen time or sensing what your kid's watching on the screen. i wanted to give the opportunity to control themselves on their own and develop their self—regulation skills, because it's necessary to teach how to use the smart devices wisely. if you smile, it also smiles. chuckles. amongst other things, piloto uses the phone's camera to teach good screen technique... piloto: distance, please, spencer. ..and its gyroscopes to teach good posture. sit up straight! blimey! and by learning to care about piloto�*s teeth, kids might also learn to do the same for theirs. thanks! now, if having children has made you want to pull your hair out — well, i know the feeling — and another c—lab start—up has been working on a solution. scanning, and then i capture — video capture — with this button. that will show you how the image looks like.

yeah. in all seriousness, many people suffer from hair loss for many different reasons and the becon device is a scanner that can help. it analyses your scalp and, using ai, gives you a diagnosis to help you choose the best products and ingredients to treat your specific condition. i was actually suffering from the hair loss for 15—20 years. in korea, there are 4 million products to take care of the hair loss condition but people never know which product will do best, so we wanted to find out the right solution. there's even a hairline simulator, should you want to lose a bit of forehead. so, this is what i would look like if i had more hair. laughs. there we go — i think that's ideal. and if i lose more of my hair, i'd look like that. that's something you can't unsee. dayoung and minsuk say that being able to develop their ideas in the safety of a large company

has its benefits. budget—wise, people—wise, it's really difficult to make a start—up because it requires a huge amount of time and money. not only are the entrepreneurs given dedicated office spaces, but they can also recruit their own project members from other samsung employees. having my own team, working with them full—time, concentrating on our dream was super good. of course, at the end of a project, samsung has the right to retain ideas and integrate them into its own products or allow the project owner to spin off as a fully—fledged company. we basically created this programme to stimulate a start—up ecosystem and promotejob creation in korea. samsung is yet another huge company that's acknowledging that creativity often comes from being nimble, like a start—up, and is trying to find ways to incorporate that spirit into its enormous corporate ecosystem.

we'll be back in korea later but now, to the us. injanuary, a company called elevenlabs released a trial version of its ai translation software intended for dubbing movies. it went viral, but not in the way they'd hoped. james clayton picks up the story. yo, boys, i may need some help. i found a room with a bunch of mob spawners. ryan reynolds' voice: have you ever wondered what it would be _ like to be someone else? morgan freeman's voice: ..with elevenlabs' ai technology, you can find out. given a minute of anyone's voice, the software can quickly put together an imitation. within days, people were imitating celebrity voices, making them say things they'd never said. ijust think i would love to get ratatouille'd. ratatouille'd? like, have a little guy up there, you know? excuse me? making me cool delicious meals. this is the point where i tell you that you're actually listening to an ai voice, but it wasn't exactly the most convincing voice. this is it. ai vows: testing | out my voice clone.

i don't think it sounds like me that much, but what do you think? i'm going to record here, too, just to — you know, to have more. my producer ben and i spoke to the ceo and co—founder of elevenlabs, mati staniszewski, for the company's first broadcast interview. so, i had a go at mimicking my own voice and, you know, it was sort of reasonably successful, although it seemed to have a bit of an australian accent. the majority of our work is based on public domain data, where majority of the voices and the work that we have are actually us — american accents. so, if ben did it, it might be more successful? ben should definitely try. the company's terms and conditions are clear that you can only clone your own voice, but not everyone has abided by its rules. 0n sites like 4chan, it's incredibly easy to find people who've taken celebrity voices and made them say racist and hateful things. elevenlabs accepts its platform has been used for hate speech.

99% of commenters are kind of positive, that we've seen, and for less than i% of what was generated, it was usually against terms of service — whether it was hate speech or variations of that. the company says only paid users can clone voices now and they're developing a new tool to track down people abusing its platform. but elevenlabs doesn't just do cloned voices... hold on, just give me a second. ..the company has another tool where users can create a unique voice completely from scratch. let's use a female gender. i'm going to do a middle age and i think even more fitting with a british accent. and i'm just going to click generate. that's going to create that entirely new voice that doesn't exist. female british-accented voice: britain's first live public broadcast was made from the factory of marconi's wireless telegraph company in chelmsford. it's never been easier to imitate a politician's voice. sleepyjoe, you have run this i

country to its absolute ground. well, at least i do run sometimes, if you know what i mean. mark nitzberg is a professor at uc berkeley's ai research lab. i asked him whether we should be worried about the presidential elections in 202a. we'll very likely see many more deepfakes than we did in the last cycle, just because it's so much simpler. and i am not sure what measures we are taking to counter what effect that might have. there are plenty of other concerns around this tech, too — for example, scams. this could make them far more believable and far easier to execute. the federal trade commission put out a statement in march, warning people that scams imitating relatives can now be incredibly convincing. elevenlabs themselves say that as ai develops, people are simply going to have to learn to trust voices they hear

and things that they see less. and kind of the wider education is just making sure that people across know that as we think about audio, as we think about texts, as we think about images, a lot of the content has been created, is likely or could be ai—generated and it's important to know that this might be — this might be the case. you know, one needs to, again, take this approach where we think about what we want in a society before we allow the release of these tools. voice cloning for the public is here to stay. it's very difficult to see how this is going to be put back in its box now. but this is clearly disruptive technology that can be used for both good and bad. hi, i'm shiona mccallum with this week's tech news. elon musk has said it's been "quite painful" and a "roller—coaster" running twitter.

musk was speaking in a wide—ranging exclusive interview with the bbc. were many mistakes made along the way? of course. i feel like think we're headed to a good place, you know, we're roughly break even. i think we're trending towards being cash flow positive very soon. if someone comes in and offers you $44 billion for twitter right now, would you take it? no. it depends on who. i suppose, if i was confident that they would rigourlsly pursue the truth, i guess i would be glad to hand it off to someone else. i don't care about the money, really, but i do want to have some source of truth that i can count on. chinese tech giant alibaba plans to rule out its own ai chatgpt—style product called tongyi qianwen. the chat bot will be integrated across alibaba's businesses in the near future. nasa has launched a new satellite to track air pollution over north america. tempo will keep a tab

on nitrogen dioxide, formaldehyde and ground—level ozone, which are key ingredients for smog. when the full—scale invasion of ukraine began, a second battle also got under way — a cyber war led by activist hackers. joe tidy has been to ukraine to speak to those who are fighting on both sides. this is killmilk, the leader of a russian hacker army that's been attacking ukraine and its allies since the invasion. he's rallied a telegram group of hackers and supporters, nearly 100,000 members strong. he wouldn't agree to a direct interview but, after weeks of asking, he sent us this video before breaking off communication. and it's notjust russians

who are hacking for russia. i'm still carrying out attacks, yeah. these two hackers, an american and a dutch national, have carried out disruptive but temporary attacks on ukraine and its allies, too. i was hijacking the ukraine embassy. no target is off limits. recently, killmilk called for attacks on hospitals in countries like germany that have donated tanks to ukraine. but the lines are clearly being blurred on the ukrainian side, too, and no—one seems to be hiding it. as the capital kyiv braced for attack, roman was helping carry out criminal hacks and building software for the war effort as part of a volunteer group. you were a big part of — and one of the leaders of — it stand for ukraine. what happened ? look at you now. i've met a guy who was responsible for the information war. i showed him all the data and all the things we've been doing. he was amazed and he said, "ok, come on, come on, "roman. "come on, we need it."

i couldn't resist. chuckles. even before he was recruited, roman confirms that his hacking team did work directly with the ukrainian authorities. so, they basically started to give us some targets and say what to do, when to do. what sort of targets were you going for in those early days? service companies. there were some disruptions in — in railway ticketing. so, you took out the ticketing system for the southern russia railway? for something like 20 hours or so. 20 hours? so, no—one could get tickets from the machines? no. that's a lot of disruption. it's the kind of attack that ukraine's cyber military could never publicly carry out themselves as a responsible nation, but is seemingly comfortable to stand back and watch. yeah, 0k. mykhailo fedorov is deputy prime minister and minister for digital transformation.

as the full—scale war broke out, it was his department that controversially set up the telegram group for the it army of ukraine. do you think the lines have been blurred between what is and was criminal hacking and what is now accepted and encouraged by the government? but is it your view that anyone hacking russia currently is not doing anything criminal? at ukraine's cybersecurity defence hq, they say they're facing attacks from dozens of other groups, too.

so, already, you've had 2,186 — is that right? viktor zhora is the leader of ukraine's cybersecurity authority. he accuses the russian military of working with groups like killnet — something killnet denies. every day, we deal with up to ten severe cyber incidents. reading the news in the uk or around the world, they might think that the cyber element to the conflict is just, you know, insignificant. what would you say to that? of course, the impact of strikes of cruise missiles is much higher than of cyber attacks. but the reason that cyber attacks can bring such impact to ukrainian infrastructure is also due to our cyber defending

capabilities and efforts. in case we were weaker, these attacks would be more destructive. some predict that the severity of attacks will increase as russia struggles on the physical battlefield, and there's a concern that hacktivists might cause serious harm if attacks get out of control. ted is one of the main coordinators of the it army of ukraine. are you in danger of gamifying hacking in this regard? you've got a leaderboard up with the amount of attacks people are carrying out. this isn't playing, is it? this is serious criminal activity. talking from the standpoint of western laws, ithink, yes, right? but when war is coming to your country, everything is changing. there are no good or bad ways to fight. thankfully, the cyber war has proven to be less destructive than the physical war. but the conflict is no doubt rewriting the rules of engagement online.

piano melody plays. no, it's not your phone ringing, but millions of people around the world might have just reached for their handsets. in korea, samsung is king, and each generation of its mobile phones comes with a new version of this... piano melody repeats. ..its over the horizon theme tune. and while i'm in the country, i've popped in to chat to one of the people who composed it. sound can deliver the message and sound can deliver the emotions. the reason we enjoy music globally is music is universal, right? so, sound design also has the grammar in which — it's a universal language that everybody can understand. and that's what we have to do. these days, phones can do loads of things, and for each thing, there's a sound — many of them created here.

even something as simple as tapping the screen needs to sound like, well, something. what do you think the sound really is? i don't know. you don't know? taps. so, that... ..that sound on the phone is actually tapping on wood? yes, it is. gangnam station, samsung building, and it's not the floor. it's a door frame. did you go around knocking lots of different things, looking for the ideal knock? iam. a lot. glass, stones and everything. that's called a foley recording. myoung nam tells me that while some sounds were completely invented from scratch, it made sense for those linked to real—world actions to have a familiar feel. now that your phone can be your credit card, for example,

your in—phone wallet should sound like your real wallet. ok. would you try hitting the card whenever you're ready? swipes card. wonderful. are there any sounds thatjust don't work on a phone? like, you know, particularly low or high sounds, like... groans deeply. i mean, the smartphone speaker cannot play the lower frequency, so we cannot even consider in the beginning of the design. can i give you another sound? yes, please. smacks his lips. wonderful. thank you. personally, i think sound design is one of the underappreciated parts of movies, tv, and, as it turns out, technology too. you can do a lot with a little here. itjust has to be the right

little, obviously. recording of lip smacking plays. recording of groan plays.. that's your new ringtone right there! and that's it from seoul in south korea for the moment. but if you'd like to see more of our adventures in this amazing city, then check us out on the socials. thanks for watching and we'll see you soon. hello. after some sunshine for many of us, hello. after some sunshine for many of us. yesterday. _ hello. after some sunshine for many of us, yesterday, today _ hello. after some sunshine for many of us, yesterday, today is _ hello. after some sunshine for many of us, yesterday, today is a - hello. after some sunshine for many of us, yesterday, today is a much - of us, yesterday, today is a much cloudier_ of us, yesterday, today is a much cloudier affair.— cloudier affair. that cloud still bake this afternoon _ cloudier affair. that cloud still bake this afternoon for- cloudier affair. that cloud still bake this afternoon for some | cloudier affair. that cloud still- bake this afternoon for some light rain and drizzle, particularly the

further west you are, not amounting to much. fog gone from coastline, here are some spells of sunshine. idea contrast across the uk. grey and gloomy where we have thick cloud, but sunshine coming through, and where it does, it should feel warmer than it has recently. this is how the rest of the afternoon chips, a lot of cloud across the uk, the best of the breaks the further east you are. possibly some light rain or drizzle from more western areas where the sun does come through, temperatures potentially getting up to 15 or 16 celsius. more like the low teens where there is cloud cover. this evening and overnight, that cloud will tend to thicken up. some outbreaks of rain developing across the spines of the country, possibly, south—east england, east anglia. not as chilly as last night. temperatures generally around four or eight celsius. this is how we sell the new week, high pressure firmly in charge. we will keep that for much of the week. some changes towards thursday and friday, but

where last week was fairly wet and often windy, the week ahead is looking drier, some spells of sunshine for all of us, and it will be feeling warm up. a lot of cloud around to somebody on monday, still some outbreaks of rain through central and south—east england, some tales of sunshine developing for many, but keeping an eye on bans of clouds moving in from the north sea, things turning dull and claiming for eastern coasts. in the sunshine, 16 or 17 celsius. cooler in areas exposed to the breeze off of the north sea. monday into tuesday, areas of high pressure, but we start to develop a more easterly wind developing into tuesday and wednesday. tuesday will bring a good deal of sunshine, more car developing, east anglia, south—east england through the day. the strength of the wind will feel the strength of the wind will feel the strength of the easterly wind, particularly the east facing coast. further west is where we will see the higher temperatures in the sunshine. 12 or 13 celsius for

eastern coasts. for the rest of the week, mostly dry, possibly some rain developing through thursday and friday across most common areas. goodbye.

bye— bye.
