Audio descriptions are a service that provides spoken narration of visual elements in various media, such as movies, television shows, and live performances. This narration describes important visual details, such as actions, settings, and facial expressions, making the content more accessible for individuals who are blind or have low vision. The audio description is typically delivered through a separate audio track or as part of the main audio. It is designed to complement the original dialogue and sound effects, ensuring that all viewers can fully understand and enjoy the experience, regardless of their visual abilities.
