Edit Captions in Video on Demand

How to edit video captions that were created using Video On Demand's Automatic Speech Recognition (ASR) feature.

This article applies to: Video on Demand

Accessibility Requirements

Automated Speech Recognition (ASR) captions are rated at 70-80% accuracy. This varies depending on the audio quality of the recording, the clarity of the speaker(s), and the amount of technical terminology used. Given these variables, ASR captions will not, by themselves, meet the accessibility standards Cornell seeks to achieve.

Video owners are responsible for editing the ASR captions to meet the WCAG AA accessibility requirement for caption accuracy.  

If you need help, human captioning is available for a fee.
