Automatic Captions and Timing For Youtube

Closed captioning is nothing new to Youtube. Neither is auto captioning which was previously restricted to politicians channels (more thoughts on that). This massive expansion should prove very useful not only to hearing impaired people, but also to people who for what ever reason can not turn on the volume or speak a different language. Here I am referring to the real close captioning translation service.

Video embedded below.

"To help address this challenge, we'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 captions will not always be perfect (check out the video below for an amusing example), but even when they're off, they can still be helpful—and the technology will continue to improve with time.

In addition to automatic captions, we’re also launching automatic caption timing, or auto-timing, to make it significantly easier to create captions manually. With auto-timing, you no longer need to have special expertise to create your own captions in YouTube. All you need to do is create a simple text file with all the words in the video and we’ll use Google’s ASR technology to figure out when the words are spoken and create captions for your video. This should significantly lower the barriers for video owners who want to add captions, but who don’t have the time or resources to create professional caption tracks.
