A year in the making, the TED Open Translation Project brings TEDTalks beyond the English-speaking world by offering subtitles, time-coded transcripts and the ability for any talk to be translated by volunteers worldwide. The project launched with 300 translations in 40 languages, and 200 volunteer translators. Find out how to translate for TED »

Generously supported by a visionary sponsorship from Nokia, the TED Open Translation Project is one of the most comprehensive attempts by a major media platform to subtitle and index online video content. It’s also a groundbreaking effort in the public, professional use of volunteer translation.

Every talk on TED.com will now have English subtitles, which can be toggled on or off by the user. The number of additional languages varies from talk to talk, based on the number of volunteers who elected to translate it.
