Using Kaltura REACH Captioning

Kaltura REACH uses automated speech recognition (ASR) to recognize words spoken in your video and provide machine-based captions for your video. Kaltura REACH captions are typically 75-85% accurate and can improve over time as the program adapts to learn your voice. Kaltura REACH also provides an editor to revise and improve the accuracy of your video captions.
