Automatic transcription services

Lecture Capture and Kaltura provide an automatic transcription service. This service is automatically available in Kaltura and may need to be activated in Lecture Capture. The transcript will become available at least 30 minutes after a recording has been made available:

  • To students via Lecture Capture
  • In the Kaltura Media Gallery.

The speech recognition software does not produce a perfect transcript. Displaying a live transcript or video captions from an automatic transcription does not necessarily meet accessibility requirements. Follow up with Student Equity and Disability Services if you need more advice on making your recordings and transcripts more accessible.
