How can it detect nearby microphones?
Also, seems like your voice would easily project farther than 2 meters, the "protection zone" of this device. That's not even the size of a room.
The explanation isn't satisfying
>What is Spectre I and how does it work?
Spectre I is a portable audio security device that creates a 2m protection zone around you. It sends out signals that are inaudible to you but can be detected by a microphone. Through customization of the signals to match the human voice, your conversations are "overlayed" when a microphone receives them. It uses local processing to prevent nearby smartphones, smart speakers, and other devices from picking up your voice. Everything happens locally on the device — nothing is sent to the cloud.
It's unclear whether it performs the task or if it's illegal, similar to a phone jammer.
I'm wondering if this device would cause issues for a nearby person's emergency communications. Seems potentially really bad.
Good thing I wore my tin-foil hat to dinner, but sadly, my friend didn't wear one, and now they can't get a timer for their cooking and the meal is ruined. Brilliant.
This part seems like BS.

Plausible but anything inaudible to you and screwing with the remote is a software or hardware upgrade away. It’s hard to imagine a sw or hw bandpass filter doesn’t stop this. Also hard to imagine smart speakers aren’t doing this already to extract your voice in a noisy environment / personalize responses.
I’d wait for this to be independently verified and understand how they propose to find microphones. Maybe they’re looking for the Wi-Fi / BT signals the speakers are emitting but something like a local nanny cam there’s no way.
And also do be doing positioning requires multiple spatially separated receivers (nothing like LIDAR). And good luck separating out other much larger sources of EM noise.
