Having closed captions along with your videos is important to help you reach out to diverse audiences, or these may be required for accessibility compliances like Section 508. Manually generating closed captions can be a lengthy and tedious task, but in today's day and age, this is not needed. You now have various tools available that use AI for automatic closed captioning. 

Video use is evolving and its consumption is changing too. According to a study, around 69% of people view videos in public places without sound and in private places, 25% view videos without sound. 

If you are the person who utilizes video in your business, be it video ads, product demos, recruitment videos and other types of video content, then you should definitely optimize for muted watching, and if not, you are losing a great number of potential customers.

According to the World Health Organization, over 5% of the world’s population – or 466 million people – have disabilities, and that is projected to increase to over 900 million by 2050.

Not adding captions to videos makes content limited to only those people who understand that specific language spoken in the video. That ultimately means limited reach to your content, whereas automatic closed captioning encourages global reach.

This article highlights the importance of closed captioning and the top free and paid automatic video captioning tools.

For instance, you can read captions when audio can't be heard, either because of the noisy environment or because of an environment that must be kept quiet, such as the library. Closed captions are identified by the [CC (Closed Captions)] symbol.

Closed captions also include descriptions of visual elements in the video as well, such as sound effects or the identity of speakers. Examples include *door knocks* *swish* etc.

Moreover, people can also watch videos in sound-sensitive environments such as hospitals. To aid with disabilities, closed captions are required by Section 508, ADA and other accessibility compliances.
