After rolling out on smart speakers and displays earlier this year, Google’s interpreter real-time translation mode finally landing on mobile. A far more handy application for such functionality, the feature arrives on both Android and iOS handsets globally, starting today.

The feature works in tandem with Assistant. Say something like, “Hey Google, be my German translator” or “Hey Google, help me speak Thai,” and the feature kicks in, offering up a real-time translated transcript and audio. The feature also offers some Smart Replies a la Gmail, to help keep the conversation going.
