A Surveillance ‘Cat-and-Mouse’ Game With AI:
In 2023, a team led by Ming Gao, now a researcher at Nanjing University, used human voices to defeat speech-recovery algorithms in a different way. Its jammer, called MicFrozen, is worn by a speaker who doesn’t want to be recorded. It listens as they talk and then generates a real-time stream of ultrasonic “anti-speech” tuned to the speaker’s voice, much like the noise-cancellation technology in your headphones. The device then sends out another layer of counterfeit speech-shaped sound to mislead any algorithm that tries to reconstruct what was lost.
Note that the “answer” to digital technologies we hate is always MOAR DIGITAL TECHNOLOGIES. For previous entries on this point, see this and this.
