Automatically Subtitling the C3

How speech processing helps the CCC subtitle project, and vice-versa.

timobaumann and Arne Köhn

Transcribing a talk comes relatively easy to fast typists, whereas turning a transcript into time-aligned subtitles for a video requires a much larger human effort. In contrast, speech recognition performance (especially for open-source-based solutions), is still poor on open-domain topics, but speech technology is able to align a given text to the corresponding speech with high accuracy. Let's join forces to generate superior subtitling with little effort, and to improve future open-source-based speech recognizers, at the same time!
