Automatic transcription and Manual Captioning 

Moderate accuracy 

How to view recordings with transcriptions 


  • In a Meeting (but not in Training), a closed LIVE caption window can be enabled for a transcriptionist to type in what is spoken by a presenter. For recorded videos, the transcription is automatic and turned on by default. (Transcription is also coming to Training as well in Fall 2020) 
  • For manual LIVE captions, the host must add the closed captioning panel and assign a participant the role of “closed captionist” 
  • Individual users manually turn captions on/off in their view 
  • Captions last for three seconds 
  • Can autogenerate a transcript of a recorded session in Meetings or Events after the recorded session is saved as an MP4 file 
  • Requires minimal background noise and will not produce a transcript if the overall quality is poor 
  • Only available in English
