I already do this but it was so I'd know Alexa heard me when I have my back to her or in another room. However, I don't think that proves that she is not or can't record prior to her name being said.
Yea, I was just helping out newbies and as a reminder. It just may indicate she is recording because each time she blurts out without provacation of her name, etc, she lights her rings.
Anyone who thinks she is "spying" on us, in any way ought to unplug the darn thing and sell it on eBay! Conspiracy theories on many topics abound, and this is just another one.
