Google has integrated a few new messaging apps into its voice commands in the Android app, so now you’ll be able to quickly send messages in your favorite clients without ever having to touch your phone.
The process works just like sending a text message, but instead of dictating to send a text, you can tell Google to send a WhatsApp message to someone. Afterwards, Google will prompt for what you’d like to send. The process works with several of the most popular messaging services, including WhatsApp, Viber, WeChat, Telegram, and NextPlus.
This is just one of the many steps Google is taking to roll as much functionality into their core Google Play services as possible, making Android a very, very compelling platform. Currently, sending these messages is only available in English, but like always Google is working on rolling that out to other languages soon.
