Where does it say transcribing? To me it sounds like it is processing voice on device into emotion markers and only the emotion markers are send to amazon. So the actual voice information would never leave the device. I do think anything else would not be possible legally because you'd need to have consent from every stranger you have a discussion with, moreso what about trade secret meetings. I can't fathom Amazon would go that way.

It doesn't. However for the last nine or more years (since work on Echo began), transcription has been far and away the #1 way Amazon processes speech - not "emotion markers" or whatever else you are dreaming up. I don't see "emotion markers" mentioned or described, and "it sounds like they are doing something else" is not really a strong argument if you're trying to guarantee that they aren't transcribing it.
