Google is rolling out an update to Google Now that allows users to dictate and send messages using messaging apps, including WhatsApp and Viber. The company announced this in a blog post.
Google Now will be able to send messages using WhatsApp, Viber, WeChat and NextPlus in English at launch, though Google plans to add more support for apps and languages.
The users have to specify which app to use by saying 'OK, Google, send a WhatsApp message to ABC' and it will make and send the message through the proper service.
