YouTube has made a great move by introducing auto-captioning to its site.

Automatic captions are being introduced on a few educational channels and Google channels (captions can be translated to other languages). This feature will likely expand to other YouTube videos in the future.

Also, you can now upload a transcript for a video and the speech recognition technology will turn it into synchronised captions.

You can read more here and here.

I'll probably find a few of the features useful as I have hearing issues. Also, if you don't understand the language spoken on the video, you'll be able to translate the captions to a language you understand (including some Indian languages). Hey, the new features will also be useful when your computer sound is not working!

Cool feature!
