TED has launched a big update to its iOS app, adding faster speed and streaming subtitles. While users will no doubt appreciate the speed improvements, TED is really excited about the latter feature, which the organization calls “the real star of the show”.

According to TED, the app is the largest content provider to use iOS6’s new subtitles feature on its streaming video service. The subtitles will follow you to Apple TV with Airplay.

“This release is a very important one to us. Our talks are translated by a team of volunteer translators worldwide. For the first time ever, their work is now available on iOS, our largest mobile platform right now,” says TED’s Thaniya Keereepart, who led the update. “The subtitle piece utilizes iOS6′s new HLS services. Our engineers have been working very closely with Apple to make it possible.”

Subtitles are available in 90 languages right from the video player.
