Automatic (machine based) captions in Kaltura
Kaltura REACH uses automated speech recognition (ASR) to provide machine-based captions for your video. Kaltura REACH captions are imperfect (70-90% accurate at best) and can improve over time as the program adapts to your voice. To revise and improve the accuracy of your video captions can be edited using the instructions below. Please contact ltsisupport@uvlc.ca for assistance or questions related to captioning.

How to manage captions
Edit captions

Turn off or delete captions
It’s recommended to turn off or delete captions only where absolutely necessary for your course. Many students request to see captions (even in their unedited form). In cases where removing captions is necessary, it’s recommended to turn them off as deleting them can be irreversible. Below you fill find step by step instructions for turning off or deleting captions.
- Navigate to your video through Course Tools, Kaltura My Media.
- Click on the pencil to the right of your video.
- Select the Captions tab.
- In the captions tab you can choose what to do with your captions:
- Selecting Don’t show on player will hide the captions.
- Selecting delete will remove the caption file from the video (Note that deleted captions cannot be recovered, and auto-generating new ones may not be possible).
