Google’s Duplex is a free service that uses artificial intelligence to book reservations through the company’s virtual assistant, but a recent report from The New York Times suggests that Duplex still relies on people working in call centers to make sure that bookings are completed properly.

How was Google duplex trained?

To make Google Duplex so realistic, Google used all of its collected conversation data and its Automatic Speech Recognition (ASR) technology to provide data points for the machine learning model. They trained each task separately and then combined all of the data to make the most effective responses.

What's Google's AI called?

Google Assistant is available on Android phones, with all recent models offering the AI system. Even devices that offer another AI system, like Samsung’s Bixby, also offer Google Assistant. Essentially, if your phone has Android, your phone has Google Assistant.
