  6. Select OK in the confirmation window.  The speed of the machine ASR captioning depends primarily on the current load being experienced by the captioning service.  During periods of light load, machine captioning, even for videos of an hour or two, usually requires no more than 10 to 20 minutes to complete.  During periods of high load on the captioning service, it may take several hours for captions to be completed.

Once completed, captions will automatically be added to the video.  Refresh the page with the video (after captions have completed) to see the captions. The machine ASR system will also auto-populate the video with AI-generated tags based on the caption content.  Users can edit these tags as normal.  Click the Edit button for the video to go to the Edit page to remove tags you don’t want.

Automated Speech Recognition (ASR) captions are rated at 70-80% accuracy.  This will vary depending on the audio quality of the recording, clarity, and understandability of any speaker(s). Users can edit the machine ASR captions to correct any errors or inaccuracies.
