Caption, Subtitle, Audio Description: Knowing Differences That Matter

 

Accessibility – It is a term that turned into a wildfire in the late 90’s when the USA passed the ADA act. Then in 1999, we had the official WCAG guidelines for all content served over “The Web” (also known as the INTERNET). The WCAG guidelines mandated that all the videos released over the web must have captions, subtitles, and audio descriptions. Failing to do so might invite legal troubles. 

So, there is definitely no confusion that captions, subtitles, and audio descriptions are absolutely necessary for any type of video content released over the internet. But many people remain confused about their functions and differences. While all of them have the primary motive of making the platform more accessible to people with disabilities, there are some distinctions between captions, subtitles, and audio descriptions that are worth noting. We will talk about all those differences and more in this blog. So, keep reading!

 

What is Captioning?

You must have watched movies where the words spoken by the actor are displayed in a textual form on the bottom part of the screen. These are called captions. They basically help the hard-of-hearing people to understand what the actors are saying. 

Captions can be of many types, the primary two types being live caption and closed caption

 

Live Caption

These are real-time captions delivered during the time of broadcasts. They are most suitable for all forms of live events. Hence, you can easily use them in sports streaming, e-sports streaming, eLearning, live events, news broadcast, and many other scenarios. 

Live captions can be either automated or done manually. There are many tools available that let you translate the words spoken into texts and showcase the texts on screen. It is a fully automated process, and hence the captions often lack the human touch. Though with advancements in technology, even automated live captions have started to highlight emotions through the use of emoticons. 

However, live captions can be added manually too! A stenographer listens to the live audio and manually types the text to display it on screen. But it will mean that the live captions will appear a few seconds after the event takes place on the screen. 

 

Closed Caption

Closed captions, also called CC in short, refer to the captions that appear on recorded videos. These captions are pre-recorded, edited, and adjusted to deliver the best viewing experience to the viewers. 

 

Use Cases of Captions

Many video and OTT platforms, including YouTube, Disney+, and many others use captions on their videos on regular basis. This helps their videos be accessible to people with hearing difficulties. 

In fact, YouTube has given its users a choice of preference for this feature. The viewers who want to have CC for the videos can turn it on by clicking on the CC button. While the viewers who don’t want to watch closed captions don’t need to bother. 

 

What Are Subtitles?

Now that you know what captions mean, you must be wondering what is a subtitle and how is it different from captions. Well, to begin with, subtitles are also very similar to captions, the only difference being their language. 

In the case of captions, the texts appear in the same language as the video. So, if you are watching the captions of an English movie, you will expect the text to come in English too! But, subtitles are in a different language, for example, you are watching an English movie but English is not your native language. So, in that case, you can have subtitles in your native language to help you understand the movie better. 

 

Use Cases for Subtitles

The video content developers use subtitles very often to localize and globalize their videos. It helps them add new consumers to their basket and scale their revenues further. 

 

What Are Audio Descriptions?

Audio descriptions are recorded audio that describes or narrates the entire video content. To understand it better, if you are watching a movie, then the audio description will precisely be the audiobook for its story. 

Audio descriptions are mainly used to help the blind and visually impaired audience. Even if they can’t view the video, audio descriptions ensure that they can still enjoy the content by listening to it. 

Most of the audio descriptions are descriptive in nature. It means that they not only narrate the story but also describe the scenes shown and the reactions delivered by the actor. It helps visually impaired people visualize the actions performed by the actors on screen.
