Ultrasound microphone jammers seem to be a real thing, so it's possible it does to some extent work.

Only for specific kinds, like MEMS.

But there's no way to detect microphones automatically, and "AI generated cancellation signals" is a word salad that doesn't mean anything.

What they probably mean is "we asked ChatGPT to tell us what waveform and frequency range to use on MEMS devices and spit out some arduino code."
