Alexa devices use an onboard DSP to detect the wakeword and maintain a rolling audio buffer. On a positive match, the DSP wakes the main CPU which combines the saved buffer and any following speech and uploads it to the cloud where Alexa lives so she can try to figure out what you meant.
No audio is uploaded without being triggered by a wakeword. Also, the “mute” button physically cuts power to the mic, and the indicator LED is hardwired to the power rail as a failsafe indicator.

Oh, I know. For reference, I work at Amazon, so always interested in where these stories come from 😂
That was more for everyone else’s edification. I worked on a plethora of Amazon devices over the course of a decade.
