Google Duplex is the technology behind a new Google Assistant feature. Duplex is a completely automated system that places calls on your behalf, complete with a natural-sounding human voice instead of a robotic one. Furthermore, Duplex is able to understand “complex sentences, fast speech and long remarks.
How do you use it?
As of now, details aren’t exactly clear, but the process will involve telling Google Assistant something along the lines of, “Call XYZ restaurant and make a reservation for four people Friday night at 7.” At this point, Google Assistant and Google Duplex will place the call, talk to whoever answers the phone at the restaurant and add the appointment to your calendar when it’s finished.
