  Should be possible to check if its the thermal mechanism by looking at the frequency response. Should act like a low pass filter because of the mics thermal mass. If the response is flat i agree with Horrowitz that its probably leaking into chip packaging. The fact that IR light still works suggests to me that it's the mic heating up.

  If you have a third party controlled voice device online in your home that controls anything other than the lights and what music to play, you're a fool who deserves what you get.

  No consumer IOT device is secure enough to totally control either your safety or security, period.
