Google I/O 2018 keynote introduced different new features. Android P gesture navigation, Google news and Google map improvements with many others. Google Duplex a behavior inside the Google assistant was one of the prominent features. The feature is not final and work is in progress but an impressive demonstration of the feature was given in the Google I/O 2018 keynote presentation. The main purpose for now served by the Google duplex function is to make reservations on phone. The AI will make reservation on your behalf over the phone.
Google’s CEO Sundar Pichai demonstrated in his presentation how Google duplex feature will reserve an appointment for a haircut around noon in a saloon if commanded. The Google assistant starts to have a discussion with the saloon management. The person on the other side did not realize that it was communicating by AI over the phone. The key addition to the Google AI were small voice gestures which made the conversation seem more human.
The Google Duplex function was also part of some controversy. Many people are not fine with the fact that they cannot tell if a human or AI is on the other side of the phone call. A point to ponder is up to what extent the AI can play a role in phone calls. Google has also responded by saying that the AI voice calling system will identify itself over the phone.See here.
