Here’s how to use Duplex, Google’s crazy new service that impersonates a human voice to make appointments on your behalf (GOOG, GOOGL)

Google has started to roll out its artificial intelligence-powered reservation booking service, called Google Duplex, to some Pixel users.
The feature debuted over the summer at Google's I/O conference, where it stunned the audience with its eerily human-sounding voice, including its usage of "um" and "ah."
Critics first questioned the ethics of AI software making phone calls without first identifying itself to the person on the line, but Google Duplex did in fact identify itself, according to multiple businesses where Business Insider made reservations.
The service is beneficial for those who are shy about placing phone calls, but it's just as simple (if not quicker) to make a reservation with OpenTable or Google Maps.

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 you've 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.
