What is Google Duplex?
Google Duplex is a service that uses AI-driven voice to make phone calls on behalf of the user, announced by CEO Sundar Pichai during the May 2018 Google I/O developers conference.
It was first demonstrated with a phone appointment, where the AI was able to understand the person on the other end of the line and respond with correct answers to questions, even inserting "ums" and pause breaks to sound like a real human.
