Yeah they had that but this is different, more interactive and something you can decide to use while your phone is ringing. Google voice currently does not have a call screening feature like the one on the pixel.
Well, GV is interactive by some definition, but awkward. You need to listen to the headset to hear the callers introduction, then type 1 to accept the call or hang out and send caller to voice mail.
Real time transcription would be much nicer, very true. GV is apparently on a lifeline while Google is trying to push Fi. Just like Duo and Hangouts.
