I still have computers from the 1990's, the 2000's, and 2010's... everything from about 2007 onward has that ability if you set it up correctly. My OG Droid Razr (circa 2011) has that ability. You are grossly underestimating what computers and phones can do. Phones (and computers) have been able to filter out distinct voices for over a decade now, close to two decades. At least, if I read your comment correctly. If I did not, and you were tongue in cheek making the point I am emphasizing, I apologize.
