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

Zoom has a variety of options for creating closed captioning in your meetings and webinars which provides subtitles of the spoken in-meeting communications. This may be used for participants to easily follow the conversations or to meet accessibility requirements.

In meetings, the host or another meeting attendee assigned by the host can provide manual captioning, an integrated third-party closed captioning service can provide the captioning, or Zoom’s live transcription feature can automatically provide captions. These same options are available with webinars, although manual captioning can only be provided by the host or a panelist. Any of these captioning options are also viewable in Zoom Rooms.

If you are unable to provide captioning manually or with a third-party service, the live transcription feature is also available but has limitations to take note of. Live transcription currently only supports English and the accuracy of the 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 or accessibility needs in your meetings and webinars, we do recommend using a manual captioner or service that may be able to guarantee a specific accuracy.

As mentioned in our Zoom blog post, we are working towards making live transcription available to all of our users in the fall of 2021. To help free account holders who want live transcription before then, we will also be offering live transcription to meeting hosts upon request. To sign up, enter your information in this form.

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