Any Zoom account can have closed captions (i.e. automatically generated subtitles to help people who are hard of hearing or where connection is poor).
The instructions are here and are as follows:
To enable Closed captioning for all users in the account:
- Sign in to the Zoom web portal as an admin with the privilege to edit account settings.
- In the navigation menu, click Account Management then Account Settings.
- Click the Meeting tab.
- Under In Meeting (Advanced), click the Closed captioning toggle to enable or disable it.
- If a verification dialog displays, click Enable or Disable to verify the change.
- (Optional) If you want to make this setting mandatory for all users in your account, click the lock icon , and then click Lock to confirm the setting.
- (Optional) Select the check boxes to enable additional features:
- Allow use of caption API Token to integrate with 3rd-party Closed Captioning services
- Enable live transcription service to transcribe meeting automatically
- Allow viewing of full transcript in the in-meeting side panel: If disabled, participants cannot view the full transcript in the side panel. They can only view captions in the video window of the meeting or webinar. Participants also won't be able to save captions.
Note: This feature requires Zoom version 5.7.0 or higher.
