Wearable Microphone Jamming

How quickly are they going to go commercial with this?

I wonder how portable these could be made to use when visiting someone who owns an Amazon Alexa device?

No one is going to buy this. It doesn't jam your voice at all. It introduces enough distortion and noise so that computer speech recognition software gets 4/5 words wrong.

Let me make a comparison. Claim: Those capchas with "type in the word you see" have an error rate of 4/5 letters when read by a computer. Yet here we are, humans, reading them just fine.

Now, if you're a conspiracy theory fake elected moon landing virus hoax person who is afraid of the government having microphones everywhere, running a keyword search on microphones placed around the park.... Still not a jammer - I'm sure whatever voice recognition software this thing confuses, the government has much better ones. Simply from the fact that most of the people they're interested in have accents so thick it's worse than some added "jammer" noise.

But to answer your question, "sounds" like they're trying to go commercial soon, because their announcement of this dirt simple product sounds like a cheap advertisement for some dick enlarging pills. meanwhile, your phone speaker can make sonic sounds since they support a sample rate of over 44khz. So can your computer.

here you go. you can google and download some files to play too. https://mynoise.net/NoiseMachines/audioJammerNoiseGenerator....

Cool research. Given that you are also jamming hearing aids and other microphones, don't think it's practical to be used in real life.

Definitely thought provoking research :)

So, if you're recording a cop in the next few years, make sure to use a waterproof phone.
