Did the old, "Translate" button seem archaic to you? Well, fret no more. The first change Google is implementing is the ability to translate instantly. Wave goodbye to the button because Google is translating as you type.
The second is slightly more useful. Along with your translation, Google will also be providing a Romanization of the text written phonetically in English. In addition to this, Google has added a new input transliteration feature for Arabic, Persian and Hindi, which allows users to enter text phonetically. Very handy if you can't type out the script with your keyboard.
Lastly, is the addition of a little speaker button that, you guessed it, let's you hear translations. Unfortunately this is only available for translating to English at the moment, but you can try it, and all the other new features, by clicking here.
