Google-Duplex-Image1

During Google I/O event 2018, Google announced Glimpse of technology known as Google Duplex.
Duplex is a new Google Assistant’s feature that can do specific tasks for you over the phone. Duplex will be able to reserve a table in your favorite restaurant, also can schedule an appointment, or call any organization to check for their opening hours.
Launch Google Assistant on your Mobile and say, “Book a table for two at Domino’s Pizza at 8 pm today,” and Duplex will do the rest. The AI feature will call the dominos pizza center and make a reservation for you. After the call, you’ll get a notification on your phone confirming the reservation.
This is the power of AI which is making our life a lot easier.
