There are many subtitle and caption generators available in the market today. In this article, you will get information on the best 10 tools to generate subtitles and captions for videos automatically. Speed up your video content queues by automating the crucial task of adding subtitles. By adding subtitles and captions to your videos automatically, you will save lots of time, efforts, and scale up your video content library swiftly!

Why Should You Use Automatic Subtitle and Caption Generator Tools?

Videos that have captions and subtitles have better audience reach. Many of your viewers might not be native English speakers. More than 50% Youtube viewers are non-English. 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.

You can always transcribe the audio and speech in your videos manually. This ensures that everything is written accurately. Then, you can get your transcriptions translated into several languages. But this process can take plenty of time, money, and efforts. It can slow down your video publishing schedule and increase your production budget.

Additional Tools for Generating Subtitles and Captions

The above 10 tools are awesome for converting your video and audio content to text, and support 50-100 languages. They have thousands or even millions of users, great affordable pricing plans, support multiple devices, and team collaboration. But if you try them and find that they don't match your quality requirements or budget constraints, we have more recommendations for you.

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. So be sure to check also out Sonix, Otter, Nova, Clideo, Rev, Subtitle Horse, Amberscript, Type Studio, and Closed Caption Creator.

Summary

They can help you to accurately, quickly, and at a low cost convert your videos and audios into text content. This text content can be used as subtitles, or as transcripts that can go in your blogs and social media content.

However, with the best 10 automatic subtitle and caption generators, you should get fast and reliably accurate results.
