John Holt Captioning Project

Mike Ridgway, formerly a member of Khan Academy's internationalization team, has developed software that makes it very easy to build captions for YouTube videos so the deaf and hard of hearing, and even speakers of languages other than English, can access these videos. While a member of the Khan team, Mike came up with an idea for an editing interface that makes it easier to produce captions than has been the case up to now.

Unable to persuade (or pay) other programmers to implement his ideas, Mike began teaching himself Javascript and PHP in January, the same time he started to build his app. has agreed to give it a try to see if we can get some of our YouTube videos captioned.
