How Audio Description Enhances Accessibility of Your Content

Have you ever found yourself in a situation in which everybody else is laughing at a joke, but you just don’t get it? Those individuals who are blind or have other visual impairments go through this every time they watch a video like standard TV shows, informative videos, work videos, study lectures, visual product descriptions, or movies.
Here is when the audio description is useful.

What is Audio Description?

The supplementary audio track that defines and provides context for crucial visual information in media and live performances is known as an audio description, often referred to as a video description. This covers significant gestures, figures, scene transitions, and text that appears on the screen. Often, they are designed for blind or visually challenged consumers so that they may comprehend and appreciate the audio track.
For those who are blind or have vision problems, the audio description is a crucial accessibility tool because it enables these people to fully enjoy movies, TV serials, and other visual content by providing descriptions of the important visual details and components appearing on the screen.
Regardless of the visual material you’re producing, whether it’s a corporate training video, a live performance, or a Hollywood film, it’s crucial to ensure everyone can experience it and comprehend what’s occurring. An audio explanation might be useful in situations like those.

How are audio descriptions different from captions?

Audio descriptions (AD) walk the viewer through what they are seeing, whereas captions use text to describe important visual details of what is being seen on screen. To put it another way, captions assist people who are deaf or hard of hearing, whereas extended audio description assist people who are blind or visually impaired.
By adding textual transcripts, closed captions, and audio explanations, videos, and audio presentations may be made more accessible. There may be captions to offer a text equivalent to the audio in a video, film, television broadcast, live event, etc., with accompanying audio.
Furthermore, the same information that is supplied in the audio presentation, such as speaker identification and sound effects, is also provided in written form via the captions.

Types of Audio Descriptions

Three primary types of audio descriptions are used in this field to guarantee that everyone can enjoy your video content.


This makes it possible for narration snippets to appear at the organic dialogue breaks in the original content. To fit inside the given time during the break, these descriptions are often brief and to the point. By doing this, it is ensured that the audio complements the information rather than detracts from it.

When a modest amount of detail has to be conveyed or when there are many pauses in the text, standard audio description works effectively.


This extends descriptive narration well beyond the audio’s normal pauses. When a longer description is necessary, listeners can pause the original material and accommodate it. The explanation will start playing before the video does in order for this to function. Then, until the audio is finished, a little pause will occur in the video. The video will restart when that happens.
When longer details and important visual cues to content are required, an audio description is the best option.


Using a tiny transmitter and headphones, a skilled audio describer delivers narration or commentary to those who require it during a live event.

Real-time audio is the best option if you want an audio description for a live event like a play, a tour, or any live event.
