How would the mics listen for the wake word if they aren't always on?
There is a mic mute button that is able to turn off the mics, which then prevents the device from waking up, as it is not receiving audio signals to process and detect the wake word. When the button is activated (== the mics are off), there is a glowing red light illuminated inside the button.
My point was that you could check to see if the linkage between that red indicator light and the power going to the mics was in software or hardware.
This is analogous to the warning light that many laptops have for when the built-in webcam is on.
It would also be possible to take a look at the hardware design and determine the linkage between the "mic mute" button light being on and power going to the mics.
The customer can set the device to provide both audio and visual indication when it "wakes up" and begins streaming to the cloud. And, of course, the customer can also press the mic mute button to avoid accidental wake up.
Yes, the FBI could try the same approach with Amazon as they are trying with Apple. For all of our sake, let's hope that Apple wins.
