Web Accessibility: Editing Automatic Closed Captions in Zoom Cloud Recordings

All Zoom meetings recorded to the cloud will receive automatic closed captions and transcripts. This article describes how to use the integrated editing tool to improve the accuracy of automatic captions.


People with hearing loss depend on media with highly accurate closed captions (approximately 99%). Zoom provides automatic machine-generated closed captions for all meetings recorded to the cloud. However, automatic captions and transcripts are only roughly 80% accurate, well below the threshold of accessibility. Use Zoom's integrated caption editing tool to improve the accuracy of automatic closed captions.

There are numerous ways closed captions benefit everyone, including:

  • Improved note taking
  • Improved attention
  • ESL support
