Google has launched its official Google Translate iPhone app, which features everything seen in the web app (released in 2008) plus a whole lot more.

We’ve checked the New Zealand app store and it’s there (for once).

The app runs on iPhone or iPod touch with iOS 3 or above.

Here’s a list of features new to the iPhone and iPod app that aren't found in the web app:

Speak to translateThe 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 translationsYou 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.

Full-screen modeAnother feature that might come in handy is the ability to easily enlarge the translated text to full-screen size. This way, it’s much easier to read the text on the screen, or show the translation to the person you are communicating with. Just tap on the zoom icon to quickly zoom in.
