YouTube service makes video more accessible

A new captioning accessibility service has been announced for the YouTube educational channels. This service will make it easier to provide text transcriptions of video and automatic caption generation. OpenSpires is interested in any service that helps bring audio video material to a wider global audience. At the moment, it’s early days but universities in the US are talking about an 80-85% success rate for correct speech to text correction.


Here’s a great overview from the Official Google blogspot by one of the engineering team.

However, like everything YouTube does, captions face a tremendous challenge of scale. Every minute, 20 hours of video are uploaded. How can we expect every video owner to spend the time and effort necessary to add captions to their videos? Even with all of the captioning support already available on YouTube, the majority of user-generated video content online is still inaccessible to people like me.

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.
