Google Now update lets you dictate messages to WhatsApp and Viber
Google Now just got an update so you can ask it to send messages using your favorite services.
In the past, you could say “OK, Google, send a message to Owen” and it would just send via your default messaging app. Now you can specify which app to use by saying “OK, Google, send a WhatsApp message to Owen” and it’ll pick the right app.
It supports WhatsApp, Viber, WeChat, Telegram and NextPlus in English at launch, though Google plans to add more support for apps and languages in the future.
