I feel creeped out by these home listening devices and I don't own one, but don't our phones already have this capability? You can turn "Ok Google" on on an android phone. I sometimes record audio, and the mic is incredibly good. Is there a substantial difference between our phones and these devices?
EDIT: Just realized the substantial difference is that Google and Amazon own all of these things. They don't control all makes and models of phones.
