Recently, I was invited by Google to a demonstration of Google Now and other apps. I'm glad I went, too, because there's far more to the service than I thought. Although not directly integrated into Now, Google Translate is a super-useful app which does a lot more than merely translating web pages or portions of text from one language to another.

For example, it allows you to record audio from a foreign speaker, translate it into your language. Then you can enter your response, and it will translate it in to the foreign speaker's language so you can communicate with each other. Another of the app's features is the ability to point the camera at some text, highlight the words you want translated and see them in your own language. That means you can read signs, menus and ingredients lists when you can't even read the letters of a different alphabet, such as Greek or Chinese.

However, as you can see in the infographic below, the app is useful only really for getting the gist of what's being said, and is no replacement for a human translator if you wanted to send a business email or translate a document for business use.
