Audio descriptions play a critical role in order to ensure that video content is accessible to blind and visually impaired people: generally speaking, audio descriptions contain a “description” of those scenes that couldn’t be understood otherwise (e.g. relying only on the audio) by blind and visually impaired people, yet are perfectly fine for their sighted peers and are relevant for the video. Developed by the Smith-Kettlewell Eye Research Institute YouDescribe is a free web service that allows any user from the Inter.Net to create audio descriptions for Youtube videos, so that blind and visually impaired people can watch those videos while hearing the audio description.
More specifically, YouDescribe provides all the tools that are necessary to author audio descriptions and consume them while watching videos. Audio-described videos can be embedded on websites and shared on social networks as well: simply put, YouDescribe “enhance” Youtube by adding support for audio descriptions.
