Back in January this year, Google Translated for Android App was refreshed with several updates to make the app easier to interact with. Among other improvements, created better dropdown boxes to help select the languages you want to translate from and into, an improved input box, and cleaner icons and layout, and speech-to-speech translation between English and Spanish.
Now today, responding to the continuing disasters in Japan, Google published a new version of Google Translate for Android that supports Conversation Mode to translate Japanese into 50 different languages in a quick, live fashion.
This version of Google Translate is available to devices running Android 2.0 and up. Some devices may have to add the Text-to-Speech Extension pack.
