At Zoom, we are hard at work to provide you with the best 24x7 global support experience during this pandemic. As part of this ongoing commitment, please review our updated Support Guidelines.



Closed captioning and live transcription Follow

Overview

Closed caption allows the host, another meeting attendee assigned by the host, or an integrated third-party closed captioning service to add closed captioning in a meeting. In a webinar, closed captioning can be typed by the host, co-host, a panelist assigned by the host, or an integrated third-party closed captioning service. Closed captioning can also be viewed while in Zoom Rooms.

If you are unable to provide captioning, Zoom also provides AI-powered live transcription for all paid accounts. This can be enabled by the host, and any participants can view the captioning as needed. Live transcription only supports English and it is recommended that you speak clearly for best results.

Note: You can only assign one participant or third-party service to provide closed captioning.

Live transcription limitations

The accuracy of Zoom’s live transcription feature depends on many variables, such as but not limited to:

  • Background noise
  • Volume and clarity of the speaker’s voice
  • Speaker's proficiency with the English language
  • Lexicons and dialects specific to a geography or community

Because of these limitations, if you are required to use speech-to-text support for any compliance needs in your meetings and webinars, we recommend using a manual captioner who may be able to guarantee a specific accuracy.

Using closed captioning in breakout rooms

If you're the meeting host, we recommend using a third-party closed captioning service if you want closed captions in breakout rooms.

If you want to a participant to type closed captions, make sure you assign them permission to type closed caption before starting the breakout room sessions:

After you start breakout room sessions, participants can click Closed Caption in the meeting controls to view closed captions. 

Notes:

  • Only one participant can be assigned to type closed captions in a meeting, thus it is only possible to have one breakout session with closed captioning.
  • Live transcription is currently not supported in breakout rooms.
