Automatic captions in YouTube videos

YouTube added a feature that generates video captions. They've combined Google's automatic speech recognition (ASR) technology with the YouTube caption system to offer automatic captions, or auto-caps for short. Auto-caps use the same voice recognition algorithms in Google Voice to automatically generate captions for video.


The feature only works for English and it's been enabled for a small number of channels that usually feature talks and interviews.



Automatic captions make YouTube videos more accessible: you can watch videos with the sound off and you can translate the captions into another language using Google Translate.
