How Google’s Duplex AI Assistant Works

How Google's Duplex AI Assistant Works


Google Duplex is the AI assistant of the future that can make phone calls on your behalf. How does this futuristic tech work? Let’s break it down:

Google’s Duplex AI assistant is powered by a neural network trained on a huge dataset of anonymized phone conversations. This allows Duplex to understand natural conversation flow, context, accents and ambient noise during calls.

  • Duplex can conduct complex, multiturn conversations, responding quickly and naturally. Its responses are generated in real time based on what the person on the other end of the call says.
  • Duplex schedules appointments, reservations or queries by first contacting the business to check availability and ensure their hours are accurate. It provides all the necessary details like contact info, reason for calling, number of people, time requested, etc.
  • If the business asks for details Duplex can’t provide, it will politely ask to call you back. It can also handle common questions, exceptions and nuances that come up during calls.
  • Duplex aims to be extremely polite, courteous and helpful at all times. Its goal is to have natural and positive conversations, and to achieve the objective you request while causing no inconvenience.

While Duplex may seem too good to be true, Google is taking an iterative approach to launch – starting with very specific use cases, collecting feedback, and continuing to improve the AI. The possibilities for time-saving and convenient AI assistants are exciting, as long as they’re built responsibly and respectfully. How’s that for a glimpse of the future?
