      Yeah I read the other comments after making mine. However everyone keeps calling it a “physical” button, and I don’t think that’s accurate. It won’t be a physical switch that opens a circuit, it will be a button that operates a transistor that opens the circuit.

      Still, I see no good reason to trust the device - especially in a medical setting.

        There’s not much difference between a direct switch and a transistor, both will cut the signal and neither is over rideable by software

          This is disingenuous at best and incorrect at worst. The mute button on the Echo is just that, a button; it is not a switch. It is software-controlled and pushing it just sends a signal to the microcontroller to take some action. For instance, one action is to turn on the red indicator light; that’s definitely not physically connected to the mute button.

          Maybe another response of pushing the button is to disable the transistor used for the microphone, but it’s more likely that it just sets a software flag for the algorithm to stop its processing of the microphone input signal. Regardless of which method it uses, the microcontroller could undoubtedly just decide to revert that and listen in, either disabling or not disabling the red light at the same time.

          But I personally don’t think it listens in when muted. I don’t think it spies on us to target ads based on what we say around it. I’m not worried that the mic mute function doesn’t work as intended.

          But I fully understand that it is fully capable of it, technically speaking.

          A transistor is controlled by software so yes, it’s absolutely over rideable.

      I’m not sure that’s the case. We have one at work and if it thinks you’re calling out to it repeatedly it will say out loud that its mic is off and that you have to enable it.

      It might just be the part that listens for “Alexa” but that audio buffer is available to the device and it can do things with it.

        This is the funniest thing I’ve read today (though I’m not sure if it is a joke).
