  Alexa/Echo devices at least can recognise voice. If you ask "Alexa, who am I?" it will try to tell you who it heard. To learn a new person you can go "Alexa, learn my voice" (I have no idea to what extent it uses this - e.g. I'd love for it to know that when it recognises my girlfriend, it should apply her music preferences from her profile on my account, but if it does it's by no means obvious). It specifically seems to recognise the voice based on the wake word - my son an I tested this by having one of us say "Alexa" and then the other saying "who am I?", and it'd consistently give the name of the person who said "Alexa".

    One use I've seen of it knowing who is talking is that it can attribute items added to a shopping or todo (or other) list with the name of the person who added it. Beyond that, I'm not at all sure what scenarios it uses that data for.

      Can we find an open source package that can analyze audio from a podcast with multiple people and determine who is speaking in a given second?
