I'll admit I'm not very interested in speech recognition of this nature when it can't disambiguate the speaker. ie. the way Amazon Echo and other voice recognition systems can't tell the difference between a human in the room and the TV. Even when one might be clearly a female voice vs. a male.

None of the voice recognition systems on the market learn my voice distinctly from my wife's or sons, and I don't want their speech triggering things on accident (especially my son's), so I don't use any of them.

I'll be more impressed when I can restrict Amazon Echo or one of these assistants to ignoring any voice that isn't at least rather similar to my own, not merely recognizing the words I'm speaking.
