Google Translate the online translation engine is now available on Apple iOS, as an app.
The new app has all of the features of the web app, plus some significant new additions designed to improve your overall translation experience.
Speak to translate
The new app accepts voice input for 15 languages, and—just like the web app—you can translate a word or phrase into one of more than 50 languages. For voice input, just press the microphone icon next to the text box and say what you want to translate.
Listen to your translations
You can also listen to your translations spoken out loud in one of 23 different languages. This feature uses the same new speech synthesizer voices as the desktop version of Google Translate we introduced last month.
Download Google Translate app for free from iTunes App Store.
