There will be some who are watching your videos in loud surroundings. Many users prefer to watch videos on mute, with over 85% of Facebook and Instagram videos being seen without audio. Hearing impaired viewers will also be able to access your video content if it has closed captions. Hence, by adding accurate subtitles in English and other languages, you can make sure that more people are able to enjoy your videos and understand your content! Over 80% of your viewers are likely to watch your videos completely if they have subtitles/captions. These are good universal design practices known as accessibility and internationalization.

Additional Tools for Generating Subtitles and Captions

You should definitely try the inbuilt auto subtitle generators inside Youtube and Facebook. They can work pretty well for English language, and a few other common languages with large audience. However, for more specialized services and features, and for good support of additional languages, it is necessary to use tools that are designed and built specially for that purpose.
