Users are able to request closed captions in Kaltura, which will return machine-generated captions within approximately 20-30 minutes. These unedited captions are not suitable for the hearing impaired, therefore, Instructors are expected to review and manually edit the mechanically generated captions, to 100% accuracy, in order to meet accessibility standards. Visit the Web Content Accessibility Guidelines (WCAG) 2.0 (opens in a new window) for additional information.
The accuracy of machine captions is dependent on the quality of the recording and the speaker’s voice. Typically, the accuracy of machine captions will be about 70-80%; therefore captions must be reviewed and manually edited to be 100% accurate before the captions can be published. Captions will remain unpublished until reviewed and edited.
