Managing closed captioning and live transcription in zoom App

Zoom provides a variety of options for adding captions to your Zoom meetings and webinars so participants are able to follow along. This can be used to meet accessibility requirements or to allow participants to follow conversations easily.

Zoom’s live transcription feature can provide automatic captioning through its closed caption settings, while a third-party closed caption service can provide manual captioning in meetings, or the host can provide the captioning manually or assign another meeting attendee to provide manual captioning. The same options apply to webinars, although the host or a panelist can only offer manual captioning. The captions can also be viewed in Zoom Rooms.

Please refer to the user guide if you would like more information on viewing closed captioning or live transcription.

Limitations of real-time transcriptions

The live transcription feature is also available if you can’t provide captioning manually or via a third-party. However, there are limitations to consider. In order to provide accurate live transcription, several variables must be taken into account, including, but not limited to:

  • Noise in the background
  • As well as the speaker’s voice volume and clarity
  • And their knowledge of English
  • Dialects and lexicons specific to a particular region or group of individuals

Due to these limitations, if your meetings or webinars will require speech-to-text support for accessibility or compliance reasons, we recommend using a manual captioner.


Providing closed captioning can only be assigned to one participant or third-party service.

How to enable meeting/webinar captions and live transcription

You are able to enable or disable the closed captioning and live transcription services as the account owner or admin with privileges. With the Closed captioning option enabled, participants or third-party services, such as the host, may add closed captions or the host can type closed captions.

    • The meeting participant is assigned the task of typing closed captions during the meeting.
    • I will type:
    • You can type closed captions manually in the closed captioning window.

How to use closed captioning in breakout rooms

In the meeting controls, participants can click Closed Caption to view closed captions after breakout sessions start. Our recommendation is that if you would like closed captions in breakout rooms, you should go through a third-party service.

Before a breakout room session starts, give the participant permission to type closed captions.


  • There can be only one person assigned to type closed captions in a meeting; therefore, a closed captioned breakout session can only be held once.
  • Breakout rooms do not support live transcription at the moment.

How to make participant requests to enable live transcription

You can also enable live transcription for your meetings and webinars as part of the registration process. Meeting controls offer this option, which eliminates the need to ask for it verbally or through chat, avoiding interruptions.
