Kaltura provides automated captions through Automated Speech Recognition (ASR) Machine Transcription.  This provides:

• Immediate access to machine-based captions (70-85% accuracy) and a “Do It Yourself” Captions Editor for increased fidelity
• Machine-based Learning with improved accuracy over time and ability to customize glossary

Keep in mind that if you use auto-generated captions, you will need to revise them for accuracy.
We recommend that you upload your video to Kaltura and then share it in your course using a link to the Kaltura recording.
