Closed captioning (subtitles) have recently been introduced to some videos on YouTube, which could potentially be a great language learning resource. The service is in beta mode at the moment – and apparently it needs a lot of work. From Dvice.com:

Engadget first spotted how weird Apple’s iPad launch video got when the feature was activated — sometimes the text is so different from what’s being said that you wonder if Google is just having a laugh. “A high-res color display” becomes “a high risk going to split,” and when one of the designers says he doesn’t have to change himself to use the iPad, the captions make it sound like he very clearly does. If you were relying on these captions, it would be a very different commercial.

The captioning is machine-generated, so it seems the software has a ways to go before this becomes a reliable means of translation!
