Back in June
, we launched five new experimental Indic languages for Google Translate on the desktop and mobile webapp. Today, we’ve updated the Google Translate for iPhone app to add these new alpha languages: Bengali, Gujarati, Kannada, Tamil and Telugu. This brings the total number of languages supported by the app to 63 languages.


The updated app supports the ability to view dictionary results for single words and to display romanizations for these new Indic languages. So even if you can’t read the script the words are written in, you can still take a shot at reading the translation.
