Audio descriptions provide additional information about what is visible on a screen. This allows media content to be accessible to persons with visual impairments.
Audio description is either live or recorded information, provided by a trained describer that provides descriptions of visual components of an event to become accessible to those who are blind or of low vision. This information is not provided with the normal recording or live performance, yet is synchronized as not to interrupt the primary event.
