AI-powered wearables — pins, pendants, glasses — are turning into always-on audio-visual recorders that capture private conversations and moments without consent.

This has sparked an escalating arms race. Early countermeasures like ultrasonic microphone jammers are already defeated by advanced AI speech-recovery models that reconstruct clean audio from noisy environments. Newer tactics shift from jamming to obfuscation: flooding systems with junk data, layered babble tapes, or real-time “anti-speech” ultrasonic signals designed to confuse reconstruction algorithms.
