Google’s automated, artificial intelligence-powered calling service duplex is now available in more countries, according to a support page updated today. In addition to the US and New Zealand, duplex is also available in Australia, Canada, and the UK.

Duplex launched as an early beta in the US via the Google assistant in late 2018. There were concerns about the use of the automated call without a restaurant or other small business’ express consent.

Duplex now has human listeners who annotate the phone calls to improve the software of duplex’s machine learning algorithms. To take over in the event the call either goes awry or the person on the other end chooses not to talk with the AI.
