Offline translations are now a lot better thanks to on-device AI

Jun 12, 2018 | Category: Google

Just about two years ago we introduced neural machine translation (NMT) to Google Translate, significantly improving accuracy of our online translations. Today, we’re bringing NMT technology offline—on device. This means that the technology will run in the Google Translate apps directly on your Android or iOS device, so that you can get high-quality translations even when you don’t have access to an internet connection.

The neural system translates whole sentences at a time, rather than piece by piece. It uses broader context to help determine the most relevant translation, which it then rearranges and adjusts to sound more like a real person speaking with proper grammar. This makes translated paragraphs and articles a lot smoother and easier to read.

Offline translations can be useful when traveling to other countries without a local data plan, if you don’t have access to internet, or if you just don’t want to use cellular data. And since each language set is just 35-45MB, they won’t take too much storage space on your phone when you download them.

To try NMT offline translations, go to your Translate app on Android or iOS. If you’ve used offline translations before, you’ll see a banner on your home screen which will take you to the right place to update your offline files. If not, go to your offline translation settings and tap the arrow next to the language name to download the package for that language. Now you’ll be ready to translate text whether you’re online or not.
