Google Translate launched a new feature that provide you with alternate translations for each phrase in the translated text.
"Just click the translated phrase and you'll see a pop-up menu of possible alternates for that phrase, as well as the original phrase highlighted in your original text. Not only can these alternative translations give a better understanding of a confusing translation, but they also allow you to help Google choose the best alternative when we make a mistake," explains Google.
By using this feature, you can help improve Google Translate.
Selecting phrase-level alternatives gives Google feedback that fits well within their system's statistical models.
