Re: Accuracy rates go captioning and transcription

You would need to achieve 97% accuracy or comprehension starts to suffer. Additionally automated closed captioning tends to caption one word at a time, which leads to the effect of watching the captions rather than the video.

Deaf/hard of hearing *hate* auto captions(myself included). YouTube provides the option to generate closed captioning, but Google won't index autocaptions given their high rate of inaccuracy; you have to fix them or upload before Google will include them in search results.

The best approach is anything that is autogenerated is checked by a human for accuracy. There's a caveat here, too, though: people can sometimes hear what they see and not realize there's an inaccuracy. Once transcripts have been fixed for accuracy, they should go through a timing program where best practices for caption display are followed.

Development on a generation tool would be ongoing. It depends on your long-term plan whether the costs to develop a tool outweighs the existing vendors out there. Two that I know of use a combination of human/technology: Automatic Sync Technologies and 3PlayMedia. Both have prices per minute 2.25-2.75 and have video description services as well.
