Artificial intelligence creates sound effects for silent videos that fool humans / Boing Boing - 0 views

  •  
    "This algorithm uses a recurrent neural network to predict sound features from videos and then produces a waveform from these features with an example-based synthesis procedure. We show that the sounds predicted by our model are realistic enough to fool participants in a "real or fake" psychophysical experiment, and that they convey significant information about material properties and physical interactions."

Fansmitter: malware that exfiltrates data from airgapped computers by varying the sound of their fans / Boing Boing - 0 views

  •  
    "demonstrate a fiendishly clever procedure for getting data off of airgapped computers that have had their speakers removed to prevent acoustic data-transmission: instead of playing sound through the target computer's speakers, they attack its fans, varying their speeds to produce subtle sounds that humans can barely notice, but which nearby devices can pick up through their microphones."

Are Fingerprints a Secure Way to Pay? | Singularity Hub - 0 views

  •  
    "Sounds lovely. But a few (mostly worried) thoughts come instantly to mind. First, our fingerprints are unique whether or not they're attached to our hand. That Sounds like a dangerous incentive to chop off a few fingers, no?"

An "ahem" detector that uses deep learning to auto-clean recordings of speech / Boing Boing - 0 views

  •  
    "Train the Deep Learning Ahem Detector with two sets of audio files, "a negative sample with clean voice/sound" (minimum 3 minutes) and "a positive one with 'ahem' sounds concatenated" (minimum 10s) and it will detect "ahems" in any voice sample thereafter."

A Survival Guide for Living in the Simulation | Issue 139 | Philosophy Now - 0 views

  •  
    "This might be a bit disappointing for you. But if you think about it, what would be a satisfying answer to the meaning of life, in the simulation or out of it? It seems difficult to think of a fully satisfying answer to a question that has been put on the most ornate pedestal of all questions. 'To love or to live' sound like something you'd read in a cheap self-help book. The Epicureans thought that the meaning of life was to seek modest pleasures. To me at least, that does not sound very satisfying."

AI call quiz: see if you can spot the sham audio of Trump and Biden | US elections 2024 | The Guardian - 0 views

  •  
    "Deepfakes have arrived to US elections, with a faked audio call purporting to be Joe Biden reaching voters in New Hampshire earlier this year. Artificial intelligence tools allow people to create spoofed audio easily and cheaply - so easily and cheaply that a journalist can do it! We created some fake audio clips of both Biden and Donald Trump using Parrot AI, an app with audio renditions of public figures that users can input words into. You can make audio of what sounds like Biden, Trump or a host of other high-profile speaking, and it sounds real-ish."

The job applicants shut out by AI: 'The interviewer sounded like Siri' | Artificial intelligence (AI) | The Guardian - 0 views

  •  
    ""After cutting me off, the AI would respond, 'Great! Sounds good! Perfect!' and move on to the next question," Ty said. "After the third or fourth question, the AI just stopped after a short pause and told me that the interview was completed and someone from the team would reach out later." (Ty asked that their last name not be used because their current employer doesn't know they're looking for a job.) A survey from Resume Builder released last summer found that by 2024, four in 10 companies would use AI to "talk with" candidates in interviews. Of those companies, 15% said hiring decisions would be made with no input from a human at all."

Quantum Computers Are Coming. The World Might Not Be Ready. - Bloomberg View - 0 views

  •  
    "As dire as that sounds, panic isn't in order just yet. Researchers are already working on "quantum-resistant" encryption. Some companies claim to have made significant progress in the field. Google, among others, is working on a new form of security for its browser that might rebuff a quantum algorithm."

'Dalek' commands can hijack smartphones - BBC News - 0 views

  •  
    "Researchers have demonstrated how garbled speech commands hidden in radio or video broadcasts could be used to control a smartphone. The clips, which sound like the Daleks from Doctor Who, can be difficult for humans to understand but still trigger a phone's voice control functionality. The commands could make a smartphone share its location data, make calls and access compromised websites."

Computers are now better than humans at recognising images | Global | The Guardian - 0 views

  •  
    "It might not sound like much, but the success of the Minwa supercomputer, which can sort a million images into a thousand predefined categories with an error rate less than the typical human, makes it the latest secret weapon of the company known as "China's Google", Baidu."

You Are Not a Digital Native: Privacy in the Age of the Internet | Tor.com - 0 views

  •  
    "If you were born around the turn of the 21st century, you've probably had to endure someone calling you a "digital native" at least once. At first, this kind of sounds like a good thing to be-raised without the taint of the offline world, and so imbued with a kind of mystic sixth sense about how the Internet should be."

The AI Revolution: Road to Superintelligence - Wait But Why - 0 views

  •  
    GREAT ARTICLE ON AI "There is some debate about how soon AI will reach human-level general intelligence-the median year on a survey of hundreds of scientists about when they believed we'd be more likely than not to have reached AGI was 204012-that's only 25 years from now, which doesn't sound that huge until you consider that many of the thinkers in this field think it's likely that the progression from AGI to ASI happens very quickly. Like-this could happen: It takes decades for the first AI system to reach low-level general intelligence, but it finally happens. A computer is able understand the world around it as well as a human four-year-old. Suddenly, within an hour of hitting that milestone, the system pumps out the grand theory of physics that unifies general relativity and quantum mechanics, something no human has been able to definitively do. 90 minutes after that, the AI has become an ASI, 170,000 times more intelligent than a human."

Is your smartphone listening to you? - BBC News - 0 views

  •  
    "Google said it "categorically" does not use what it calls "utterances" - the background sounds before a person says, "OK Google" to activate the voice recognition - for advertising or any other purpose. It also said it does not share audio acquired in that way with third parties."

AI Experts Issue Warning Against Facial Scanning With a "Dangerous History" - 0 views

  •  
    "But researchers at New York University's AI Now Institute have issued a strong warning against not only ubiquitous facial recognition, but its more sinister cousin: so-called affect recognition, technology that claims it can find hidden meaning in the shape of your nose, the contours of your mouth, and the way you smile. If that sounds like something dredged up from the 19th century, that's because it sort of is."

The GPS app that can find anyone anywhere | Technology | The Guardian - 0 views

  •  
    "The algorithm behind what3words took six months to write. Sheldrick worked on it with two friends he had grown up with. Mohan Ganesalingham, a maths fellow at Trinity College, Cambridge, and Jack Waley-Cohen, a full-time quiz obsessive and question-setter for Only Connect. After the initial mapping was complete, they incorporated an error-correction algorithm, which places similar-sounding combinations a very long way apart."

The Chinese government is putting tracking chips into school uniforms to watch every move kids make / Boing Boing - 0 views

  •  
    "The uniforms allow school officials, teachers, and parents to keep track of the exact times that students leave or enter the school, Lin Zongwu, principal of the No. 11 School of Renhuai in Guizhou Province, told the state-run newspaper Global Times on Dec. 20. If students skip school without permission, an alarm will be triggered. If students try to game the system by swapping uniforms, an alarm also will sound, as facial-recognition equipment stationed at the school entrance can match a student's face with the chip embedded in the uniform."

Mosquito early warning app detects the insects from their buzz | Science | The Guardian - 0 views

  •  
    "Artificial intelligence researchers have developed a mosquito early warning system that raises the alarm when the insects are near by detecting the whine of their wingbeats. The system uses an app that can run on a £20 mobile phone to analyse sounds in the environment and issue a warning if it hears the telltale buzz as a mosquito swoops past."
