Google is experimenting with a new tool that will call people on your behalf, holding entire conversations to set up appointments, order food, arrange meetings and much, much more. Google Assistant used human voices, complete with 'ummms' and 'ahhhs' in the middle of sentences, where it sounds natural.

Built into Google Assistant, the new technology that was unveiled at Google IO is called Google Duplex. It can interact with people like a normal human after understanding your request. In a live conversation, Assistant is able to field many questions and even knows to ask how long the wait is without being prompted.

This technology isn't quite ready at the moment, but Google is rolling out what Pichai called an “experiment.” During holidays, restaurants and businesses often have different hours. Google plans to use its Assistant to make one phone call to a bunch of businesses, then update its holiday hours for web searches.

Google also built a new structure for the voice of its assistant called “Wavenet,” it introduces six more natural-sounding voices, including, for some reason, the dulcet tones of singer John Legend.

The technology is poised to bring big changes to how we interact with our voice-activated devices, which is why Google executives told CNET that the firm will 'proceed with caution' in rolling out the technology to everyone. 

The Google Duplex system is capable of carrying out sophisticated conversations and it completes the majority of its tasks fully autonomously, without human involvement. The system has a self-monitoring capability, which allows it to recognize the tasks it cannot complete autonomously.

“The technology is directed towards completing specific tasks, such as scheduling certain types of appointments. For such tasks, the system makes the conversational experience as natural as possible, allowing people to speak normally, like they would to another person, without having to adapt to a machine” Google said in a blog post. 

This technology is definitely too advanced right now and needs further refinement before we see it on our mobile phones. Google hasn't revealed a timeline and has repeatedly warned that it is a very fragile technology that needs to be implemented carefully due to its negative repercussions.
