European Union (EU) officials have proposed new rules that could restrict and even ban some uses of artificial intelligence (AI) within its borders. That could include some technology developed by U.S. and Chinese-based tech giants. The rules would be the most significant international effort to regulate the use of AI to date.

The Coordinated Plan on Artificial Intelligence 2021 Review, put forth by the 27-nation bloc, could set a new standard for technology regulation.

If passed, rules could impact how facial recognition, autonomous vehicles, and even algorithms that are employed in online advertising are used across the EU. It could also limit the use of AI and machine learning as it applies to automated hiring, school applications and credit scores. It would ban AI outright in situations deemed risky, including government social scoring systems where individuals are judged on their behavior.

This could be the first-ever legal framework on AI, and the EU has said the new Coordinated Plan with Member States would guarantee the safety and fundamental rights of people and business, while also strengthening AI uptake, investment and innovation across the EU.

With these landmark rules, the EU is spearheading the development of new global norms to make sure AI can be trusted, Margrethe Vestager, the European Commissions executive vice president for the digital age, said in a statement. By setting the standards, we can pave the way for to ethical technology worldwide and ensure that the EU remains competitive along the way.

The EU has maintained that the new AI regulations could ensure that the Europeans can trust what AI has to offer, and would create flexible rules that could address the specific risks posed by AI-based systems. AI systems considered a clear threat to the safety, livelihoods and rights of people will be banned.

High-risk use of AI would include critical infrastructure, including transport, which could put the lives and health of citizens at risk; educational and vocational training, such as the scoring of exams; and law enforcement where it could interfere with peoples fundamental rights. In those cases, the high-risk AI systems would be subject to strict obligations before they could be put on the market, and would require logging of activity to ensure traceability of results, high quality of datasets, high level of security and accuracy, and appropriate human oversight measures to minimize risk.

AI is a means, not an end, explained EU Commissioner for Internal Market Thierry Breton.

It has been around for decades but has reached new capacities fueled by computing power, added Breton. This offers immense potential in areas as diverse as health, transport, energy, agriculture, tourism or cyber security. It also presents a number of risks. Todays proposals aim to strengthen Europes position as a global hub of excellence in AI from the lab to the market, ensure that AI in Europe respects our values and rules, and harness the potential of AI for industrial use.

This isnt the first time the EU has attempted to create regulation around new technology that surpasses anything else in the world. This has mainly been focused on privacy, including search results, but also in how personal information can be used by tech firms.

Now it addresses the developing technologies of AI and machine learning, but the question is whether such a hard line could limit the efforts by the tech giants. Or is this the best course of action to ensure privacy, security and to maintain a fair and level playing field for all involved?

First and foremost, allowing technologies to be developed unilaterally without any oversight is an effective vote for market dominating behavior, technology industry analyst Charles King of Pund-IT, told ClearanceJobs.

Weve seen it happen among tech industry behemoths, including Facebook and Google, and in countries, like China and government agencies in the U.S. and elsewhere, King added.

The EU hold all the cards right now, and the tech firms will have to play by their rules or ignore the European market. The latter really isnt an option.

Along with trying to place some restraints on potentially damaging behavior, the EU is also acting from a position of historic strength, explained King. The organization has aggressivelypursued businesses that it believes are acting against the interests of consumers and markets, and has passed regulations including GDPR that have successfully influenced global businessesand markets.

One of the biggest concerns would be whether such strict regulations simply make it too hard for businesses to play by the EUs rules. AI could be one of those areas where this could seem like stifling but in the end could ensure that control over the technology is, in fact maintained accordingly.

The writer and futurist Arthur Clarke famously asserted, Any sufficiently advanced technology is indistinguishable from magic,' said Jim Purtilo, associate professor of computer science at the University of Maryland. If thats the definition, then todays decision systems based on artificial intelligence technologies surely qualify as magic. They are subtle, tremendously complex methods which defy full explanation as to how a given result was computed.

Part of the issue is in understanding exactly what is entailed by AI. While it is easy to think of the science-fiction version of a thinking computer or android, in reality it is just ever-more complicated algorithms.

There has always been some aura of mystery to it. In some sense, AI is the area that stops being AI once we understand it, added Purtilo.

Many fairly ordinary forms of computing for example logic systems and computer memory once fell under a heading of AI research, he noted. What differs today is the scale of decisions that people will leave to machines. It used to be that at least programmers had an understanding of how their programs computed a result, but with AI the programmers generally cant work back to justify how an outcome was reached. That programs accuracy not a big deal when all it is doing is tagging photos of your friends in an album on your phone, but it becomes a very big deal for individuals who fall under suspicion of police based on wide deployment of facial recognition technology.

Given the understanding of what is, and to some extent what is not, AI, the question then becomes whether the EU is taking its regulation of AI too far?

Im not particularly afraid of computer programs, but Im terrified of the bureaucrats who use them thinking they escape responsibility by pretending to be mere servants of science which, by virtue of AI methods, is somehow settled even if not explained, warned Purtilo.

I thus see the EUs move as being less about AI than it is about policy, Purtilo told ClearanceJobs. Government practices should offer transparency and accountability, but as AI methods offer neither, these proposed regulations represent a first attempt to push back at opaque technologies that cloak the basis for impactful decisions.

That could stifle AIs development, or perhaps simply allow it to be better controlled and managed.

Whether or not this latest effort will succeed is anyones guess, said Pund-ITs King. But the EU is taking action because it believes it should and because it can.

While pesticide spraying protects crops against pests, weeds, and diseases, it can also be harmful to neighbouring crops and wildlife.

This unwanted movement of pesticides, known as spray drift, however, could potentially be trackable, thanks to a project developed between Monash University's Faculty of Information Technology, Bard AI, PentaQuest, and AgriSci.

The project combines an artificial intelligence model and augmented reality to enable farmers to see a real-time visual representation of the possible spray drift on their phones. The presentation also allows farmers to view the impact the spray drift could have on neighbouring crops if spraying were to occur during poor conditions, such as when there are strong wind speeds.

Farmers are also able use to the system to understand "what if" scenarios to improve their spray plan and understand the potential impact of spray drift.

"Information alone does not change behaviour and the use of advanced technology doesn't ensure the adoption of new platforms by farmers. By incorporating game-like design applications which drive better training and engagement outcomes, together with AI-driven decision support modelling, we're able to deliver continuous adoption and accurate decision support that informs farmers appropriately," Monash University Faculty of IT interim dean Ann Nicholson said.

Bard AI founder Ross Pearson said the solution has initially been developed to focus on spray drift for large acres but believes it could be used for other applications.

"Our solution combines leading-edge thinking and technology in behavioural science and probabilistic modelling to deliver an engaging experience for farmers that supports them through better decision-making," he said.

In March, Australian agtech firm Agerris rolled outs its "drone on wheels" robot onto the Victorian-based SuniTAFE Smart Farm to support the farm's operations and train technical staff on-site.

The Digital Farmhand was developed to help farmers improve crop yield, pest and weed detection, as well as reduce the need for pesticides.

Each mobile roving robot runs on solar energy and features navigation sensors, laser sensors, infrared sensors, cameras. It also has an artificial intelligence system that can create weed heat maps, as well as detect each individual crop and determine its yield estimation, plant size, and fruit and flowering count.

An AI-driven space debris-dodging system could soon replace expert teams dealing with growing numbers of orbital collision threats in the increasingly cluttered near-Earth environment.

Every two weeks, spacecraft controllers at the European Space Operations Centre (ESOC) in Darmstadt, Germany, have to conduct avoidance manoeuvres with one of their 20 low Earth orbit satellites, Holger Krag, the Head of Space Safety at the European Space Agency (ESA) said in a news conference organized by ESA during the 8th European Space Debris Conference held virtually from Darmstadt Germany, April 20 to 23. There are at least five times as many close encounters that the agency's teams monitor and carefully evaluate, each requesting a multi-disciplinary team to be on call 24/7 for several days.

"Every collision avoidance manoeuvre is a nuisance," Krag said. "Not only because of fuel consumption but also because of the preparation that goes into it. We have to book ground-station passes, which costs money, sometimes we even have to switch off the acquisition of scientific data. We have to have an expert team available round the clock."

The frequency of such situations is only expected to increase. Not all collision alerts are caused by pieces of space debris. Companies such as SpaceX, OneWeb and Amazon are building megaconstellations of thousands of satellites, lofting more spacecraft into orbit in a single month than used to be launched within an entire year only a few years ago. This increased space traffic is causing concerns among space debris experts. In fact, ESA said that nearly half of the conjunction alerts currently monitored by the agency's operators involve small satellites and constellation spacecraft.

ESA, therefore, asked the global Artificial Intelligence community to help develop a system that would take care of space debris dodging autonomously or at least reduce the burden on the expert teams.

"We made a large historic data set of past conjunction warnings available to a global expert community and tasked them to use AI [Artificial Intelligence] to predict the evolution of a collision risk of each alert over the three days following the alert," Rolf Densing, Director of ESA Operations said in the news conference.

"The results are not yet perfect, but in many cases, AI was able to replicate the decision process and correctly identify in which cases we had to conduct the collision avoidance manoeuvre."

The agency will explore newer approaches to AI development, such as deep learning and neural networks, to improve the accuracy of the algorithms, Tim Flohrer, the Head of ESA's Space Debris Office told Space.com.

"The standard AI algorithms are trained on huge data sets," Flohrer said. "But the cases when we had actually conducted manoeuvres are not so many in AI terms. In the next phase we will look more closely into specialised AI approaches that can work with smaller data sets."

For now, the AI algorithms can aid the ground-based teams as they evaluate and monitor each conjunction alert, the warning that one of their satellites might be on a collision course with another orbiting body. According to Flohrer, such AI-assistance will help reduce the number of experts involved and help the agency deal with the increased space traffic expected in the near future. The decision whether to conduct an avoidance manoeuvre or not for now still has to be taken by a human operator.

"So far, we have automated everything that would require an expert brain to be awake 24/7 to respond to and follow up the collision alerts," said Krag. "Making the ultimate decision whether to conduct the avoidance manoeuvre or not is the most complex part to be automated and we hope to find a solution to this problem within the next few years."

Ultimately, Densing added, the global community should work together to create a collision avoidance system similar to modern air-traffic management, which would work completely autonomously without the humans on the ground having to communicate.

"In air traffic, they are a step further," Densing said. "Collision avoidance manoeuvres between planes are decentralised and take place automatically. We are not there yet, and it will likely take a bit more international coordination and discussions."

Not only are scientific satellites at risk of orbital collisions, but spacecraft like SpaceX's Crew Dragon could be affected as well. Recently, Crew Dragon Endeavour, with four astronauts on board, reportedly came dangerously close to a small piece of debris on Saturday, April 24, during its cruise to the International Space Station. The collision alert forced the spacefarers to interrupt their leisure time, climb back into their space suits and buckle up in their seats to brace for a possible impact.

According to ESA, about 11,370 satellites have been launched since 1957, when the Soviet Union successfully orbited a beeping ball called Sputnik. About 6,900 of these satellites remain in orbit, but only 4,000 are still functioning.

Artificial intelligence is learning how to dodge space junk in orbit - Space.com

Todays voice assistants are still a far cry from the hyper-intelligent thinking machines weve been musing about for decades. And its because that technology is actually the combination of three different skills: speech recognition, natural language processing, and voice generation.

Each of these skills already presents huge challenges. In order to master just the natural language processing part? You pretty much have to re-create human-level intelligence. Deep learning, the technology driving the current AI boom, can train machines to become masters at all sorts of tasks. But it can only learn one at a time. And because most AI models train their skill set on thousands or millions of existing examples, they end up replicating patterns within historical dataincluding the many bad decisions people have made, like marginalizing people of color and women.

Still, systems like the board-game champion AlphaZero and the increasingly convincing fake-text generator GPT-3 have stoked the flames of debate regarding when humans will create an artificial general intelligencemachines that can multitask, think, and reason for themselves. In this episode, we explore how machines learn to communicateand what it means for the humans on the other end of the conversation.

This episode was produced by Jennifer Strong, Emma Cillekens, Anthony Green, Karen Hao, and Charlotte Jee. Were edited by Michael Reilly and Niall Firth.

Jim: I don't know if it was AI If they had taken the recording of something he had done... and were able to manipulate it... but I'm telling you, it was my son.

Strong: The day started like any other for a man... were going to call Jim. He lives outside Boston.

And by the way... he has a family member who works for MIT.

Were not going to use his last name because they have concerns about their safety.

Jim: It was a Tuesday or Wednesday morning, nine o'clock I'm deep in thought working on something,

Strong: That is... until he received this call.

Jim: The phone rings and I pick it up and it's my son. And he is clearly agitated. This, this kid's a really chill guy but when he does get upset, he has a number of vocal mannerisms. And this was like, Oh my God, he's in trouble.

And he basically told me, look, I'm in jail, I'm in Mexico. They took my phone. I only have 30 seconds. Um, they said I was drinking, but I wasn't and people are hurt. And look, I have to get off the phone, call this lawyer and it gives me a phone number and has to hang up.

Strong: His son is in Mexico and theres just no doubt in his mind its him.

Jim: And I gotta tell you, Jennifer, it, it was him. It was his voice. It was everything. Tone. Just these little mannerisms, the, the pauses, the gulping for air, everything that you could imagine.

Strong: His heart is in his throat...

Jim: My hair standing on edge

Strong: So, he calls that phone number A man picks up and he offers more details on whats going on.

Jim: Your son is being charged with hitting this car. There was a pregnant woman driving whose arm was broken. Her daughter was in the back seat.. is in critical condition and they are, um, they booked him with driving under the influence. We don't think that he has done that. This is we've, we've come across this a number of times before, but the most important thing is to get him out of jail, get him safe, as fast as possible.

Strong: Then the conversation turns to money hes told bail has been set and he needs to put down ten percent.

Jim: So as soon as he started talking about money, you know, the, the flag kind of went up and I said, excuse me, is there any chance that this is a scam of some sort? And he got really kind of, um, irritated. He's like, Hey, you called me. Look, I find this really offensive that you're accusing me of something. And then my heart goes back in my throat. I'm like, this is the one guy who's between my son and even worse jail. So I backtracked

[Music]

My wife walks in 10 minutes later and says, well, you know, I was texting with him late last night. Like this is around the time probably that he would have been arrested and jailed. So, of course we text him, he's just getting up. He's completely fine.

Strong: Hes still not sure how someone captured the essence of his sons voice. But he has some theories...

Jim: They had to have gotten a recording of something when he was upset. That's the only thing that I can say, cause they couldn't have mocked up some of these things that he does. They couldn't guess at that. I don't think, and so they, I think they had certainly some raw material to work with and then what they did with it from there. I don't know.

Strong: And its not just Jim who's unsure We have no idea whether AI had anything to do with this.

But, the point is we now live in a world where we also cant be sure that it didnt.

Its incredibly easy to fake someones voice with even a few minutes of recordings and teenagers like Jims son? They share countless recordings through social media posts and messages.

Jim: I was quite impressed with how good it was. Um, like I said, I'm not easily fooled and man, they had it nailed. So, um, just caution.

Strong: Im Jennifer Strong and this episode we look at what it takes to make a voice.

[SHOW ID]

Zeyu Gin: You guys have been making weird stuff online.

Strong: Zeyu Jin is a research scientist at Adobe This is him speaking at a company conference about five years ago showing how software can rearrange the words in this recording.

Key: I jumped on the bed and I kissed my dogs and my wifein that order.

Zeyu: So how about we mess with who he actually kissed. // Introducing Project VoCo. Project VoCo allows you to edit speech in text. So lets bring it up. So I just load this audio piece in VoCo. So as you can see we have the audio waveform and we have the text under it. //

So what do we do? Copy paste. Oh! Yeah its done. Lets listen to it.

Key: And I kissed my wife and my dogs.

Zeyu: Wait theres more. We can actually type something thats not here.

Key: And I kissed Jordan and my dogs.

Strong: Adobe never released this prototype but the underlying technology keeps getting better.

For example, heres a computer-generated fake of podcaster Joe Rogan from 2019... It was produced by Squares AI lab called Dessa to raise awareness about the technology.

Rogan: 10-7 Friends, I've got something new to tell all of you. Ive decided to sponsor a hockey team made up entirely of chimps.

Strong: While it sounds like fun and games experts warn these artificial voices could make some types of scams a whole lot more common. Things like what we heard about earlier.

Mona Sedky: Communication focused crime has historically been lower on the totem pole.

Strong: Thats federal Prosecutor Mona Sedky speaking last year at the Federal Trade Commission about voice cloning technologies.

Mona Sedky: But now with the advent of things like deep fake video now deep fake audio you you can basically have anonymizing tools and be anywhere on the internet you want to be. anywhere in the world and communicate anonymously with people. So as a result there has been an enormous uptick in communication focused crime.

Balasubramaniyan: But imagine if you as a CFO or chief controller gets a phone call that comes from your CEOs phone number.

Strong: And this is Pindrop Security CEO Vijay Balasubramaniyan at a security conference last year.

Balasubramaniyan: Its completely spoofed so it actually uses your address book, and it shows up as your CEOs name... and then on the other end you hear your CEOs voice with a tremendous amount of urgency. And we are starting to see crazy attacks like that. There was an example that a lot of press media covered, which is a $220,000 wire that happened because a CEO of a UK firm thought he was talking to his parent company so he then sent that money out. But weve seen as high as $17 million dollars go out the door.

Strong: And the very idea of fake voices... can be just as damaging as a fake voice itself Like when former president Donald Trump tried to blame the technology for some offensive things he said that were caught on tape.

But like any other tech its not inherently good or bad its just a tool... and I used it in the trailer for season one to show what the technology can do.

Strong: If seeing is believing...

How do we navigate a world where we cant trust our eyes... or ears?

And so you know... what youre listening to... Its not just me speaking. I had some help from an artificial version of my voice filling in words here and there.

Meet synthetic Jennifer.

Synthetic Jennifer: Hi there, folks!

Strong: I can even click to adjust my mood

Synthetic Jennifer: Hi there.

Strong: Yeah, lets not make it angry..

Strong: In the not so distant future this tech will be used in any number of ways for simple tweaks to pre-recorded presentations even... to bring back the voices of animated characters from a series

In other words, artificial voices are here to stay. But they havent always been so easy to make and I called up an expert whose voice might sound familiar..

Bennett: How does this sound? Um, maybe I could be a little more friendly. How are you?

Hi, I'm Susan C. Bennet, the original voice of Siri.

Well, the day that Siri appeared, which was October 4, 2011, a fellow voice actor emailed me and said, Hey, we're playing around with this new iPhone app, isn't this you? And I said, what? I went on the Apple site and listened... and yep. That was my voice. [chuckles]

Strong: You heard that right. The original female voice that millions associate with Apple devices? Had no idea. And she wasnt alone. The human voices behind other early voice assistants were also taken by surprise.

Bennett: Yeah, it's been an interesting thing. It was an adjustment at first as you can imagine, because I wasn't expecting it. It was a little creepy at first, I'll have to say, I never really did a lot of talking to myself as Siri, but gradually I got accepting of it and actually it ended up turning into something really positive so

Strong: To be clear, Apple did not steal Susan Bennetts voice. For decades, shes done voice work for companies like McDonalds and Delta Airlines and years before Siri came out she did a strange series of recordings that fueled its development.

Bennett: In 2005, we couldn't have imagined something like Siri or Alexa. And so all of us, I've talked to other people who've had the same experience, who have been a virtual voice. You know we just thought we were doing just generic phone voice messaging. And so when suddenly Siri appeared in 2011, it's like, I'm who, what, what is this? So, it was a genuine surprise, but I like to think of it as we were just on the cutting edge of this new technology. So, you know, I choose to think of it as a very positive thing, even though, we, none of us, were ever paid for the millions and millions of phones that our voices are heard on. So that's, that's a downside.

Strong: Something else thats awkward... she says Apple never acknowledged her as the American voice of Siri thats despite becoming an accidental celebrity... reaching millions.

Bennett: The only actual acknowledgement that I've ever had is via Siri. If you ask Siri "Who is Susan Bennett?" she'll say, I'm the original voice of Siri. Thanks so much, Siri. Appreciate it.

Strong: But its not the first time shes given her voice to a machine.

Bennett: In the late 70s when they were introducing ATMs I like to say it was my first experience as a machine, and you know, there were no personal computers or anything at that time and people didn't trust machines. They wouldn't use the ATMs because they didn't trust the machines to give them the right money. They, you know, if they put money in the machine they were afraid they'd never see it again. And so a very enterprising advertising agency in Atlanta at the time called McDonald and Little decided to humanize the machine. So they wrote a jingle and I became the voice of Tilly the all-time teller and then they ultimately put a little face on the machine.

Strong: The human voice helps companies build trust with consumers...

Bennett: There are so many different emotions and meanings that we get across through the sound of our voices rather than just in print. That's why I think emojis came up because you can't get the nuances in there without the voice. And so I think that's why voice has become such an important part of technology.

Strong: And in her own experience, interactions with this synthetic version of her voice have led people to trust and confide in her to call her a friend, even though theyve never met her.

Bennett: Well, I think the oddest thing about being the voice of Siri, to me, is when I first revealed myself, it was astounding to me how many people considered Siri their friend or some sort of entity that they could really relate to. I think they actually in many cases think of her as human.

Strong: Its estimated the global market for voice technologies will reach nearly 185-billion dollars this year... and AI-generated voices? are a game changer.

Bennett: You know, after years and years of working on these voices, it's really, really hard to get the actual rhythm of the human voice. And I'm sure they'll probably do it at some point, but you will notice even to this day, you know, you'll listen to Siri or Alexa or one of the others and they'll be talking along and it sounds good until it doesn't. Like, Oh, I'm going to the store. You know, there's some weirdness in the rhythmic sense of it.

Strong: But even once human-like voices become commonplace... shes not entirely sure that will be a good thing.

Bennett: But you know, the advantage for them is they don't really have to get along with Siri. They can just tell Siri what to do if they don't like what she says, they can just turn it off. So it is not like real human relations. It's like maybe what people would like human relations to be. Everybody does what I want. (laughter) Then everybody's happy. Right?

Strong: Of course, voice assistants like Siri and Alexa arent just voices. Their capabilities come from the AI behind the scenes too.

Its been explored in science fiction films like this one, called Her about a man who falls in love with his voice assistant.

Theodore: How do you work?

Samantha (AI): Well... Basically I have intuition. I mean.. The DNA of who I am is based on the millions of personalities of all the programmers who wrote me, but what makes me me is my ability to grow through my experiences. So basically in every moment I'm evolving, just like you.

Strong: But todays voice assistants are a far cry from the hyper-intelligent thinking machines weve been musing about for decades.

And its because that technology... is actually many technologies. Its the combination of three different skills...speech recognition, natural language processing and voice generation.

Speech recognition is what allows Siri to recognize the sounds you make and transcribe them into words. Natural language processing turns those words into meaning... and figures out what to say in response. And voice generation is the final piece... the human element... that gives Siri the ability to speak.

Each of these skills is already a huge challenge... In order to master just the natural language processing part? You pretty much have to re-create human-level intelligence.

And were nowhere near that. But weve seen remarkable progress with the rise of deep learning helping Siri and Alexa be a little more useful.

Metz: What people may not know about Siri is that original technology was something different.

Strong: Cade Metz is a tech reporter for the New York Times. His new book is called Genius Makers: The Mavericks Who Brought AI to Google, Facebook, and the World.

Metz: The way that Siri was originally built... You had to have a team of engineers, in a room, at their computers and piece by piece, they had to define with computer code how it would recognize your voice.

Strong: Back then... engineers would spend days writing detailed rules meant to show machines how to recognize words and what they mean.

And this was done at the most basic level often working with just snippets of voice at a time.

Just imagine all the different ways people can say the word hello or all the ways we piece together sentences explaining why time flies or how some verbs can also be nouns.

Metz: You can never piece together everything you need, no matter how many engineers you have no matter how rich your company is. Defining every little thing that might happen when someone speaks into their iPhone You just don't have enough person-power to build everything you need to build. It's just too complicated.

Strong: Neural networks made that process a whole lot easier They simply learn by recognizing patterns in data fed into the system.

Metz: You take that human speech You give it to the neural network And the neural network learns the patterns that define human speech. That way it can recreate it without engineers having to define every little piece of it. The neural network literally learns the task on its own. And that's the key change... is that a neural network can learn to recognize what a cat looks like, as opposed to people having to define for the machine what a cat looks like.

Strong: But even before neural networks Tech companies like Microsoft aimed to build systems that could understand the everyday way people write and talk.

And in 1996, Microsoft hired a linguist Chris Brocket... to begin work on what they called natural-language AI.
