This can happen to anyone, even to normal people. But a visually challenged person has to face trouble whenever no description is provided in videos. Therefore they require audio descriptions to find out the relevance of the video content and feel more comfortable and connected with it. The descriptions are placed to ensure it doesn’t hurt the content and look natural.
In the videos with audio descriptions, you must have seen that along with the voice of the lead role, a supporting voice also keeps on explaining the events and characters from behind so that even the visually challenged people can understand the video content; this is simply an audio description. It is an audio-narrated description of visual elements of TV programs.

No doubt, creating audio descriptions is a daunting task. Therefore, companies prefer outsourcing their work to an external support team specializing in audio description services. But not all can outsource due to cost or lack of budget.
To help make your video more accessible to people with visual disabilities, we provide some methods to help you create audio descriptions.
Watching your videos throughout allows you to understand the video properly. It makes you familiar with all the visual moments that need to be specified in the wiring process. It also helps you understand where there is no dialogue and needs to be noted for further work.
Now you must start writing the script, describing the scenes and other details in the video. While writing scripts for your videos, you must ensure that lines fit into the gaps between dialogues. By keeping the content precise and crisp, you can enhance the audio description and prevent it from colliding with other existing audio.
After completing a clear and concise script, it's time to record it in a professional tone and voice to make it impressive. The voice narration should depict the essence of your video with a perfect explanation of its various elements. The voice must look professional and clear. Always bear in mind that your voice should not sound like a robot.
The next task you have to do is to bring your audio description file into the post-production software. Here you have to add your narration file to the video and adjust the audio and volume to make it more understandable. While you also need to make sure that the audio works fine, can be heard clearly with the video, and doesn’t look vague.
After preparing the audio description, you must export an original video, audio file, and description narration as one MP3 or WAV file. Once you export the file, you almost reach the point of availing the benefits of audio description in your video.

Once uploaded, you can see a pop-up button, allowing users to turn it on and get the option to listen to the video content with clear descriptions in available languages. The entire process is not so hard; you can easily perform it with the right tools and software.

Adding a user-selectable soundtrack allows your viewers to toggle between the original soundtrack – without an audio description, and the secondary version – with an audio description. Now, the option to publish a secondary audio description completely depends upon the capabilities of your media player.
Let’s say; for example, a viewer can have an option for two tracks, one with a description and the second without a description. Now users get the option to choose any one of the two audio tracks. The original and secondary soundtracks may merge with audio description tracks to give users an optimal experience. A secondary audio track with a description is sufficient for users and allows them to toggle for an enhanced experience.
The approach merges the original soundtrack and additional audio description into a single track. This method creates and publishes two versions of the same content, preventing it from getting obscure. The two created versions have – one with an audio description and the other without it.

The method helps record a presentation with a slide deck containing critical information that can be explained, such as statistical graphs, etc.
The method is appropriate when other audio description techniques are unavailable to the publisher. It works as an advisory technique but has minimal support across video players. HTML5 video helps users to use WebVTT description files. The screen should be used to read the file for users.
