Blind Innovation – Internet Experience For The Blind – On Demand Stops For A Scene TTS Describer Voice?

I was thinking. To create an Internet experience for the blind. An idea would be to create on demand stops in TV series or movies that describe the scene with affordable text to voice software.

I think this can be done rather cheaply and easy for Youtube or other online media. The person just listens to the video. Then press a key to get a TTS voice reading some info text during the pause. Enters the resume button and you get a better experience.
