Alexa and Siri Can Hear Hidden Commands
Just out of curiosity, what&#x27;s the frequency range that a typical mic can pick up the signal from? The article did not specially mention about the range instead it said inaudible.<p>And here is another article I found that mentions the normal 20-20kHz frequency response range: <a href="http:&#x2F;&#x2F;blog.shure.com&#x2F;mic-basics-frequency-response&#x2F;" rel="nofollow">http:&#x2F;&#x2F;blog.shure.com&#x2F;mic-basics-frequency-response&#x2F;</a><p>Isn&#x27;t that mostly overlap with the human ear capability? I understand each person is different, etc. But just curious the specifics.
