Accessibility and Kaltura REACH Automated Captioning
Captions for accessibility and search

Better serve the needs of your users and meet today’s increasingly stringent accessibility requirements. Making sure everyone can use your video content also protects your institution from liability. Captions are a major component of accessibility. Automated captions take the stress out of captioning. Just as important, providing an accessible video player ensures viewers will be able to engage with your content. But accessibility goes beyond just content; it’s a mindset. Kaltura sees accessibility not just as a checklist, but as a state of mind.
