Google has launched a free language translation app for the iPhone, available to download from the Apple app store.
The new app accepts voice input for 15 languages and allows users to translate words or phrase into one of more than 50 languages. Users can also listen to translations spoken out loud in 23 languages.
The Google Translate app is available in all iOS supported languages, but can only be used on an iPhone or iPod Touch iOS version 3 or later.
The app has all the features of the Google Translate HTML5 web app, launched in August 2008.
