Where to start in the TED Translator Program?

TED's TED Translator program (formerly TED's Open Translation Project / OTP) is a community of volunteers who translate TED Talks, TED-Ed videos and TEDx Talks into their languages and transcribe TEDx Talks in the original language, to help spread ideas to a global audience. If you're just getting started, check out this page, which explains how the program works and how to sign up. We recommend that you also watch our series of short tutorials, and then come back here to OTPedia, where you will find multiple other helpful resources.

TED Translator program structure and workflow

Inaugurated in 2009, the TED Translator program is a global volunteer effort to subtitle TED Talks, TEDx Talks and TED-Ed videos, and enable the inspiring ideas in them to crisscross languages and borders. Every talk is uploaded to the TED Translators Program's subtitling partner, Amara, which provides an easy online subtitling interface. TED Talks and TED-Ed videos come ready with transcripts provided by TED, while volunteers may also transcribe TEDx talks in their original languages.

Volunteer translators should be fluently bilingual in the source and target languages, and volunteer transcribers should be fluent in the transcription language. Volunteers should be knowledgable of subtitling best practices. All subtitles are reviewed by an experienced volunteer, who has subtitled at least 90 minutes of talk content. Before publication, reviewed translations are approved by a Language Coordinator or TED staff member. Language Coordinators are skilled, experienced volunteers who help develop their language communities.

Volunteers have 30 days to complete each task. At the review or approval stage, the reviewer or Language Coordinator may send the task back to the original contributor, explaining what additional edits are required before the review or approval can be completed. Volunteers are required to collaborate while working on a review or approval. To learn more about our rules for collaboration, see this article.


We have a lot of resources for volunteers who wish to learn about transcribing and translating in the OTP. The TED Translator program section on TED.com and the OTP Learning Series tutorials are a great introduction, but you will want to read the more detailed guides to learn about very useful tips and strategies that will make your volunteer work in the TED Translator program much easier. Below, you will find resources divided into 5 sections: Amara (how to use the Amara subtitling interface), Transcription (how to transcribe TEDx Talks), Translation (how to translate subtitles), Reviewing (how to review subtitles) and Editing OTPedia (how to create new content on our Wiki).


TED Translators use Amara as a subtitling tool. Here are some resources to help you master its easy interface.

Amara tips and guidelines

Image shows the controls box in the Amara interface.
Users can review controls and guidelines right from the subtitling interface

You can review the basic guidelines at any time from the Amara editor, by clicking "TED Guidelines" in the "Keyboard controls" area.

To report a bug on Amara, send an email to TEDsupport@amara.org.

Making sure the video is on the TED team

Amara provides subtitling support for multiple video hosting services, and anyone can add a video to Amara. However, before you start working on a talk, make sure that it was properly added to the official TED team on Amara, by following this guide. Please do not start working on the talk before it has been added to the TED team; otherwise, your work may not get published. If you come across a TEDx talk that has not yet been added to the TED team, you can request that it's added to the right team on Amara by using this form.

Advanced Amara tools

Japanese LC Yasushi Aoki created a set of tools which allow user to get more information out of Amara or access additional features. The tools make it possible to look up a user's task info (follow the status of past tasks), the subtitle info (the edit history of a set of subtitles), the history of subtitles recently published in a given language, and community statistics.


Volunteers subtitle talks using an easy online interface at Amara.org
TED provides captions for TED Talks and TED-Ed videos, while volunteers caption videos in the ever-growing library of 35+ thousand TEDx talks. A transcript allows the talk to be translated into other languages and makes it accessible to Deaf and hard-of-hearing viewers. Thanks to same-language subtitling, even monolingual volunteers can help spread ideas all around the world. Visit the main TED transcription page at TED.com/transcribe.

Please do not attempt to transcribe videos that lack speech (such as performances, music without lyrics, etc.) Instead, share the video with us at translate@ted.com so we can remove it from Amara.

Here are some resources that can help you in transcribing talks:

Transcribing tips and guidelines

How to find something to transcribe

Getting social with transcripts

  • Guide to organizing a transcribeathon
  • A short promo video about how anyone can transcribe talks (to be played at TEDx events)
  • The TED Trasnlators group on Facebook, where volunteer transcribers and translators can connect with one another

See also the More about the TED Translator program section below.


We accept all fluently bilingual volunteers as translators. In our workflow, translations are also reviewed before they are published, and you need more experience before you start reviewing (see the section on reviewing below). In the TED Translator program, you don't only translate from English: there are TEDx talks in many other languages waiting to get transcribed and translated. And don't forget that if you feel confident enough, you can also translate from your first language into English. Even if you're not a native speaker, a native speaker will review or approve your subtitles, and without your help, viewers all over the world who speak English won't be able to learn about the amazing ideas in the talks given in your language. Visit the main TED translation page at TED.com/translate.

Here are some resources that will help you in translating in the OTP:

Translation tips and guidelines

The OTP Learning Series tutorials are a great way to pick up the basics

How to find something to translate

  • Tutorial on how to find videos to subtitle
  • Instructions on how to check if the talk was added correctly to Amara
  • Find TEDx talks to translate in lists of TEDx talks grouped by subject
  • Follow the TED Translators Twitter to get updates on TEDx Talks in need of an English translation
  • Find a TEDx event near you and search for their talks on Amara
  • If you find a TEDx talk that has not yet been added to the TED team on Amara, use this form to add it (note that the talk will first need to be transcribed, before it can be translated).

Getting social with translations

See also the Community section below.


As mentors and quality-checkers, reviewers have a very important role. Watch the tutorial on reviewing for useful reviewing tips and strategies

We ask that you transcribe at least 90 minutes of talks before you start reviewing transcripts, and that you translate at least 90 minutes of talks before you start reviewing translations in the target language. This will allow you to learn from the edits and comments made by more experienced reviewers, and earn the knowledge necessary to mentor other volunteers and improve their work. It is completely fine if you feel you need to acquire even more experience, or even if you choose not to review at all. If you find your work has been waiting for a review for a long time, you can try reaching out to reviewers you've worked before, via their TED profile or Amara messages, or you can ask for a review in your language's Facebook group (use the main I translate TEDTalks group if you're looking for help with English transcripts or translations). In order to find something to review, follow the same instructions as when searching for a talk to translate or transcribe, but select the "Review" task in the filter list on Amara.

Here are some resources that will help you in reviewing in the TED Translator program:

Editing OTPedia

OTPedia is a community-created Wiki, and we encourage you to set up an account and start creating content for the TED Translator community. You can learn the basics of Wiki editing from this guide.

OTPedia in other languages

The links on the left will lead you to sections of OTPedia in other languages. Many language communities have a robust collection of resources specific to their linguistic needs. If you can't find the resources you are looking for in your language, go ahead and create an article, ideally in collaboration with your Language Coordinators and other volunteers who work in your language (whom you can find in your language's group on Facebook). Some language communities have also translated some of the English guides linked to above, which is especially helpful for monolingual transcribing volunteers.

Issues and support

The TED Translator community is here to help you. Below, you will find suggestions about what to do when you come across an issue.

Language Coordinators

Language Coordinators are skilled, experienced volunteers who help develop their language communities. You can reach out to them with issues of subtitling and translation.

TED Translator workshops and marathons

Volunteers subtitling talks at the 2014 TEDxKrakow transcribeathon
TED Translator workshops are gatherings, organized by and for volunteers, which are an excellent way to strengthen the ties in your local Translator community, learn about new strategies and solutions in transcribing and translating, share TED Translator stories and make life-long friendships. To learn about how to organize a TED Translator workshop, see the OTP Workshop Kit. And here, you can find some stories about past workshops, written by volunteers.

Marathon events are gatherings where volunteers transcribe, translate or review talks for a few hours, usually organized in collaboration with a TEDx event. To learn how to organize a transcribeathon, translateathon or a reviewathon, see this guide.

TED Translators and TEDx

The TEDx program supports independent organizers who want to create a TED-like event in their own community. TED Translator program volunteers and TEDx organizers and team members are two communities who are passionate about TED and united by the common goal of spreading great ideas across the world. As such, TED Translators and TEDx volunteers often collaborate by forming transcription and translation subteams around a TEDx event, inviting TED Translator volunteers to attend a TEDx event and possibly promote the TED Translator program from the stage, inviting TED Translator volunteers to talk about the TED Translator program at TEDx organizer workshops, helping each other out through the transcription and translation process and organizing transcription and translation marathons.

Here are some resources that may be helpful in getting involved with the TEDx community as an TED Translator program volunteer:

  • Find a TEDx event near you and contact the organizer
  • Learn how to organize a transcribeathon
  • Read the guide to TEDx-TED Translators collaboration
  • Read Polish LC Kinga Skorupska's article on the close collaboration between the Polish TED Translator and TEDx communities
