Biden robocall: Audio deepfake fuels election disinformation fears

Published

Share this:

The 2024 White House race faces the prospect of a firehose of AI-enabled disinformation, with a robocall impersonating US President Joe Biden already stoking particular alarm about audio deepfakes.

“What a bunch of malarkey,” said the phone message, digitally spoofing Biden’s voice and echoing one of his signature phrases.

The robocall urged New Hampshire residents not to cast ballots in the Democratic primary last month, prompting state authorities to launch a probe into possible voter suppression.

It also triggered demands from campaigners for stricter guardrails around generative artificial intelligence tools or an outright ban on robocalls.

Disinformation researchers fear rampant misuse of AI-powered applications in a pivotal election year thanks to proliferating voice cloning tools, which are cheap and easy to use and hard to trace.

“This is certainly the tip of the iceberg,” Vijay Balasubramaniyan, chief executive and co-founder of cybersecurity firm Pindrop, told AFP.

“We can expect to see many more deepfakes throughout this election cycle.”

A detailed analysis published by Pindrop said a text-to-speech system developed by the AI voice cloning startup ElevenLabs was used to create the Biden robocall.

The scandal comes as campaigners on both sides of the US political aisle harness advanced AI tools for effective campaign messaging and as tech investors pump millions of dollars into voice cloning startups.

Balasubramaniyan refused to say whether Pindrop had shared its findings with ElevenLabs, which last month announced a financing round from investors that, according to Bloomberg News, gave the firm a valuation of $1.1 billion.

ElevenLabs did not respond to repeated AFP requests for comment. Its website leads users to a free text-to-speech generator to “create natural AI voices instantly in any language.”

Under its safety guidelines, the firm said users were allowed to generate voice clones of political figures such as Donald Trump without their permission if they “express humor or mockery” in a way that makes it “clear to the listener that what they are hearing is a parody, and not authentic content.”

– ‘Electoral chaos’ –

US regulators have been considering making AI-generated robocalls illegal, with the fake Biden call giving the effort new impetus.

“The political deepfake moment is here,” said Robert Weissman, president of the advocacy group Public Citizen.

“Policymakers must rush to put in place protections or we’re facing electoral chaos. The New Hampshire deepfake is a reminder of the many ways that deepfakes can sow confusion.”

Researchers fret the impact of AI tools that create videos and text so seemingly real that voters could struggle to decipher truth from fiction, undermining trust in the electoral process.

But audio deepfakes used to impersonate or smear celebrities and politicians around the world have sparked the most concern.

“Of all the surfaces — video, image, audio — that AI can be used for voter suppression, audio is the biggest vulnerability,” Tim Harper, a senior policy analyst at the Center for Democracy & Technology, told AFP.

“It is easy to clone a voice using AI, and it is difficult to identify.”

– ‘Election integrity’ –

The ease of creating and disseminating fake audio content complicates an already hyperpolarized political landscape, undermining confidence in the media and enabling anyone to claim that fact-based “evidence has been fabricated,” Wasim Khaled, chief executive of Blackbird.AI, told AFP.

Such concerns are rife as the proliferation of AI audio tools outpaces detection software.

China’s ByteDance, owner of the wildly popular platform TikTok, recently unveiled StreamVoice, an AI tool for real-time conversion of a user’s voice to any desired alternative.

“Even though the attackers used ElevenLabs this time, it is likely to be a different generative AI system in future attacks,” Balasubramaniyan said.

“It is imperative that there are enough safeguards available in these tools.”

Balasubramaniyan and other researchers recommended building audio watermarks or digital signatures into tools as possible protections as well as regulation that makes them available only for verified users.

“Even with those actions, detecting when these tools are used to generate harmful content that violates your terms of service is really hard and really expensive,” Harper said.

“(It) requires investment in trust and safety and a commitment to building with election integrity centred as a risk.”

ByteDance says ‘no plans’ to sell TikTok after US ban law

A new US law requires TikTok to sever all ties with its Chinese parent ByteDance or face a ban in the United States
Share this:

Chinese tech giant ByteDance has said it has no plans to sell TikTok after a new US law put it on a deadline to divest from the hugely popular video platform or have it banned in the United States.

US lawmakers set the nine-month deadline on national security grounds, alleging that TikTok can be used by the Chinese government for espionage and propaganda as long as it is owned by ByteDance.

The Information, a tech-focused US news site, reported that ByteDance was looking at scenarios for selling TikTok without the powerful secret algorithm that recommends videos to its more than one billion users around the world.

ByteDance denied it was considering a sale.

“Foreign media reports about ByteDance exploring the sale of TikTok are untrue,” the company posted Thursday on Toutiao, a Chinese-language platform it owns.

“ByteDance does not have any plans to sell TikTok.”

TikTok has been a political and diplomatic hot potato for years, first finding itself in the crosshairs of former president Donald Trump’s administration, which tried unsuccessfully to ban it.

It has forcefully denied any link to the Chinese government, and said it has not and will not share US user data with Beijing.

TikTok says it has also spent around $1.5 billion on “Project Texas”, under which US user data would be stored in the United States.

Its critics say the data is only part of the problem, and that the TikTok recommendation algorithm — the “secret sauce” for its success — must also be disconnected from ByteDance.

TikTok CEO Shou Zi Chew has said the company will take the fight against the new law to the courts, but some experts believe that for the US Supreme Court, national security considerations could outweigh free speech protection.

– Bullish investors –

The estimated valuations of TikTok are in the tens of billions of dollars, and any forced sale would present major complications.

Among those with deep enough pockets, US tech giants such as Instagram-parent Meta or Google would likely be blocked from buying the app over competition concerns.

Further, many investors consider TikTok’s recommendation algorithm to be its most valuable feature.

But any sale of such technology by a Chinese company would require approval from Beijing, which designated such algorithms as protected technology following Trump’s attempt to ban TikTok in 2020.

Beijing has so far vocally opposed any forced sale of TikTok, saying it will take all necessary measures to protect Chinese companies.

While TikTok is a global phenomenon, it represents a small fraction of ByteDance’s revenue, according to analysts and investors. 

ByteDance has enjoyed explosive growth in recent years, becoming one of the most valuable companies in the world. Its international investors, including US firms General Atlantic and SIG as well as Japan’s SoftBank, have stakes worth billions.

“TikTok US is a very small part of the overall business. It is an exciting part of the story, for sure, but… relative to the overall size, it’s a very small part,” ByteDance investor Mitchell Green, of US-based Lead Edge Capital, told CNBC television last month.

“If it was kicked out of the US, we would not sell.”

Five things we learned at the China Auto Show

Published

The consumer tech giant is the latest entrant to China's cut-throat EV market, with its new SU7 model the star of the show
Share this:

One of China’s largest auto shows kicked off in Beijing on Thursday, with electric vehicle makers keen to show off their latest designs and high-tech accessories to consumers in the fiercely competitive market.

Here are the key developments from Auto China’s first day of action:

– Xiaomi –

The consumer tech giant is the latest entrant to China’s cut-throat EV market, with its new SU7 model the star of the show.

Less than one month after its launch, almost 76,000 pre-orders have been placed, Xiaomi said, an accumulation of orders that will take months to deliver given its current production capacity.

Xiaomi boss Lei Jun was swarmed at Auto China on Thursday by legions of loyal fans, eager to follow the entrepreneur’s every move around the convention complex.

– XPeng –

Among car giant Tesla’s main rivals in the Chinese market is XPeng, which announced plans to begin large-scale deployment of AI-assisted driving in its vehicles in May.

“The AI learns the driver’s habits and can then imitate their driving” and enhance security, company boss He Xiaopeng told an audience while presenting the X9, a seven-seater “so spacious it can accommodate five bicycles in its trunk”.

– CATL –

Also present at the show was Chinese battery giant CATL, founded in 2011 in the eastern city of Ningde and now the undisputed global leader in EV batteries.

Its factories produce more than a third of car batteries sold worldwide and are equipped in models from a long line of foreign manufacturers including Mercedes, BMW, VW, Tesla, Toyota, Honda and Hyundai.

Responding Thursday to one of the main criticisms of EVs — long charging times that restrict mobility — CATL announced a remedy: “Shenxing Plus”, an ultra-fast battery pack that the firm says earns one kilometre (0.62 miles) in range for every second of charging.

– Nio –

In contrast to much of the EV industry, Chinese automaker Nio focuses on battery-swap technology rather than recharging individual vehicles.

The Shanghai-based firm founded 10 years ago said Thursday it had accumulated nearly 2,500 battery swapping points across China.

Nio also presented its ET7, a sedan model the firm claims has a range of 1,000 kilometres.

– Tencent-Toyota alliance –

Japanese auto-making juggernaut Toyota also announced Thursday that it would join hands with Chinese tech and gaming giant Tencent in AI, a bid to capitalise on local consumers’ increasing appetite for advanced smart car features.

The cooperation will apply to Toyota vehicles sold in China, said Toyota, which like other foreign manufacturers, has struggled to keep up in the ultra-competitive market as the industry shifts to electric.

US to give Micron $6.1 bn for American chip factories

US lawmakers have approved billions of dollars to support the onshoring of semiconductor production
Share this:

Micron is set to receive up to $6.1 billion in grants from the US government to help build its semiconductor plants in New York and Idaho, the White House said Thursday.

The award, to be announced by President Joe Biden as he travels to Syracuse, New York, is the latest in a series of efforts by Washington to bring semiconductor production back to the country.

The United States has been working to ensure its lead in the chip industry, especially with regards to the development of artificial intelligence — both on national security grounds and in the face of competition with China.

The investment will help Micron “bring back leading-edge memory chip manufacturing to the United States for the first time in 20 years,” Chuck Schumer of New York, the Senate majority leader, told reporters.

The $6.1 billion in direct funding comes under the CHIPS and Science Act, a major package of funding and tax incentives passed by Congress in 2022 to boost research and US semiconductor production.

The White House said the funds will go to supporting construction of two facilities in Clay, New York, and one in Boise, Idaho, where Micron is headquartered.

The US Commerce Department will also make up to $7.5 billion in proposed loans available under a preliminary deal.

Micron is set to invest up to $125 billion across both states over the next two decades “to build a leading-edge memory manufacturing ecosystem,” according to the White House.

The US chipmaker’s total investment is due to create more than 70,000 jobs, including 20,000 direct construction and manufacturing roles.

– Supply chain shocks –

While semiconductors were invented in the United States, the White House noted that the country makes just around 10 percent of the world’s chips now — and “none of the most advanced ones.”

Micron CEO Sanjay Mehrotra called the step a “historic moment” for US semiconductor manufacturing, saying its US investments will “create many high-tech jobs.”

“Leading-edge memory chips are foundational to all advanced technologies,” said Commerce Secretary Gina Raimondo.

She added that returning the development and production of advanced memory semiconductor technology to the country is “crucial for safeguarding our leadership on artificial intelligence and protecting our economic and national security.”

Chips are needed in powering everything from smartphones to fighter jets, and are increasingly in demand by automakers, especially for electric vehicles.

But the global chip industry is dominated by just a few firms, including TSMC in Taiwan and California-based Nvidia.

The United States is dependent on Asia for chip production, making it vulnerable to supply chain shocks, such as during the Covid-19 pandemic or in the event of a major geopolitical crisis.

“We’re already seeing AI revolutionize our world and grow at an unprecedented pace,” said Schumer. 

“We cannot, cannot have these chips made overseas, especially by competitors like China. We cannot have them be the only supplier,” he added.

Apart from the grants to Micron, Biden is also expected to announce four new “workforce hubs” in the Upstate New York region, the state of Michigan, as well as the cities of Philadelphia and Milwaukee.

According to senior government officials, such hubs are a way to spur more commitments from employers and educational institutions.
