My bad. I searched for “Meta” instead of “Facebook.” Quite a few other red flags in that press release.
> Haiket is launching the Beta trial from today, with a pipeline of future innovation for early adopters, including a pioneering silencing technology that will allow users to speak privately in public, with voice communication that only your device can hear.
Does anyone else think this sounds beyond ridiculous?
This is fairly straightforward - you have the device spew out noise with similar characteristics to human speech (ie. random overlapping syllables in the speaker's voice). Take a recording then subtract the random syllables.
Only your device can do the subtraction, because only your device knows the waveform it transmitted.
Obviously in a room with lots of reverb this will be a bit harder, since you will also need to subtract the reflection of what was transmitted with a room profile and deal with the phone moving in the room, but it sounds far from impossible.
Surely this only works if you're using the phone as a speakerphone (and are therefore almost certainly being an arsehole in public[0])?
[0] Because if it was an actual speakerphone situation, hiding your voice would be stupid.
