It is a process of converting audio into text and displaying it along with running video on the screen.
We often watch videos in languages that we are not fluent in. Can we fully understand the content of the video? No. In the same way, think about deaf people. People who can’t hear any audio can’t consume any content at all.
But, you don't have to worry about this issue. It has a very simple solution. The solution is called Captioning.
Captioning does the work of speech to text conversion. It converts all the audio content into words. This text is played on the screen along with the video content. These captions act as ‘audio’ for deaf people.
So all your hearing-impaired customers can read the captions on the screen. Thus they understand the video content of your web page.
By using captioning on your website you are also helping the customers who do not understand English fluently. They can read the captions in their preferred language. In this way, your content reaches all kinds of consumers.
Types of Captioning:
Closed captions: Captions that can be turned on or off according to one’s need.
Open Captions: Captions that are a permanent fixture on a video.
Live Captions: Captions for live streaming. They are created by typing, steno captioning or respeaking.
Subtitles: These are usually white/yellow letters with a black rim or drop shadow.
Subtitles for the Deaf and Hard of Hearing (SDH): These are subtitles with information such as sound effects, speaker identification, and other nonspeech features.
Styles of Captioning:
Pop on: These are one or two lines of captions. They remain on screen for a few seconds before they disappear.
Roll-Up: These captions roll up one after the other either at the top or at the bottom of the screen.
Paint on: These are very similar to Roll-Up captions. Here instead of the text rolling up, individual words are painted from left to right.
