Google announced new features to make devices smarter and more useful to open its yearly developers' conference. The announcements came at Google's I/O 2018 conference in Mountain View, California.

Google Duplex

"So what you're going to hear is the Google Assistant actually calling a real barber’s to schedule the appointment for you.

Hello, how can I help you?

Hi, I'm calling to book a woman's haircut for a client. I'm looking for something on May 3rd.

Sure, give me one second.

Mm-hmmm.

That was a real call you just heard."

Google Chief Pichai said the demonstration was the result of the company's research and development over many years in the areas of natural language, deep learning and text-to-speech. Google calls the technology Duplex. The idea is to create machines that sound and act more human-like in interactions with people.

Continued Conversation

Another new feature related to Assistant is called Continued Conversation. Until now, users have had to say "Hey Google" each time they asked a question or wanted help. But now, a user can issue more than one command – such as a follow-up question – for up to eight seconds, and Assistant will answer.

Gmail Smart Compose

The latest new tool for Gmail is an auto-complete feature called Smart Compose. It uses AI to suggest ways to finish sentences as they are written. For example, "I haven't seen you" might be auto-completed to "I haven't seen you in a while and I hope you're doing well."

Digital Wellbeing

Google says it recognizes many users are trying to find the right balance in life with technology. Sometimes they would like to break away from their devices to be able to spend time "on better things." New features with this in mind can help users prevent overuse of technology.

A Dashboard will provide users detailed information about how much time they are spending on which parts of their device. When the device is placed face down, a new feature will put the device on hold and silence it so the user can center on other things. A Wind Down Mode feature can let users enter the time they want to go to bed. At that time, the device will again go silent and the front of the device will dim to help users disconnect before bed.
