Last year, we were able to get almost all the talks captioned +in time for streaming. Participants found them very useful for +understanding different technical terms, names, accents, and so on. +We’d love to be able to pull that off again this year, and it would be +great to have you on board. + +We’ve set up ${backstage} as the backstage area where you can view the +videos and resources uploaded so far. You can access it with the +username "${backstage-user}“ and the password ”${backstage-password}“. +Please keep the backstage password and resources secret. If you see a +talk that you’d like to caption, you can e-mail me at +sacha@sachachua.com and I can reserve it for you. Then you can correct +any misrecognized words, fix capitalizations, remove filler words as +needed, and so on. + +You’ll probably want to work with either the VTT or the TXT versions +(VTT is WebVTT format and has timestamps), but you can check the other +talk resources in case the speaker has posted scripts or other useful +things.
