Google is bringing Pixel users one step closer to never having to make another phone call again thanks to a new voice-enabled tool that can schedule appointments and book dinner reservations for you.

Duplex, the newest artificial intelligence tool for Google Assistant, has started rolling out to Pixel phone owners, a Google spokesperson confirmed to Business Insider. The technology can perform actual phone calls for you in order to make you a haircut appointment, or book a restaurant reservation.

Google debuted the technology back in May at its annual I/O conference, but never provided a clear timeline of when Duplex would be available for customer use. With the rollout,not all Pixel users will have access to the technology right away, but our device did have Duplex software enabled.

Take a look at how you can use Google Duplex to make a reservation:

To get started, all you have to do is ask your Google Assistant to make a restaurant reservation.

You only get three options off the bat that are (by default) near your location, so to get different results, you can ask more pointed questions — such as type of food, price range, or neighborhood.

When Google presented the technology earlier this year, it showed Duplex making a reservation at a salon. However, in our tests, we could only get the technology to work with restaurant reservations.

Once youve identified the restaurant you want to book, ask Google Assistant to make a reservation there in order to engage the Duplex feature.

Your Assistant will ask a series of questions: how many people the reservation is for, what time you want to book, and even if your reservation time is flexible in case the restaurant is booked up already.

For some restaurants, Duplex wont be able to make reservations. It could be because the restaurant doesnt take phone reservations, or the business has disabled the use of Duplex there for booking appointments. Google Assistant doesnt specify.

At some places where Duplex technology is not available, Google Assistant will suggest using OpenTable instead. While Duplex wont make a call to the restaurant for you, you can still avoid making a phone call for a reservation this way.

But if Duplex technology can be used for your reservation, Duplex takes care of the booking for you. Itll ask permission to use your phone number in the booking process before calling the restaurant.

After the reservation has been successfully booked, youll receive an email confirming your table. I called the restaurants where I booked reservations to confirm that they were made successfully.

You can manage your restaurant reservations by asking Google Assistant to view your reservations. Itll pull all your reservations and scheduled events from your email and calendar, too.

Google first debuted the Duplex technology over the summer. But the Duplex voice came off so eerily human-sounding at the demonstration that it raised ethical questions about the use of AI to make phone calls without telling the other person on the line they were speaking to technology.

Google's initial introduction of the Duplex booking technology was met with much skepticism and criticism over the ethics of using artificial intelligence software that was so human-sounding to make phone calls.

Google quickly responded and said it would ensure transparency measures were taken, which would include ensuring Duplex properly identified itself on the phone as an AI-powered voice when making reservations.

In writing this article, Business Insider made reservations at several restaurants using Duplex technology. Restaurant employees later said that Duplex immediately identified itself when it called to book a reservation, and that it was easy to tell they were speaking with an automated voice.
