Do you have a link? I assumed a low pass filter was applied to the signal to reduce unnecessary data transmission. I have heard about what you're saying and I'm not dismissing it. One could run their television through a low pass filter to get around such tracking, right?

That's kind of what I was implying with one of my other replies. This filtering is something that Alexa/Googs should be doing on thier end. Their mics should only be listening in the frequency ranges of what human voices exist.
