Live Closed Captioning (CC) in Zoom is called Captions. This can be helpful in meetings for participants who are deaf, hard-of-hearing, different levels of language proficiency, and participants in loud places by giving them a way to follow along. 

Turning Closed Captioning On and off

The host of the meeting should enable transcription to ensure that the option is available for guests. Once enabled, it is up to the participant to turn on closed captioning for themselves.

To enable live transcription as the host, click More in the bottom menu > Captions... > Show Captions

Any participant that would like to view closed captioning needs to enable it for themselves. Click the More button in the bottom menu > Captions... > Show Captions

To Turn off closed captioning, click Hide Captions

Make Closed Captioning Better 

These are the best practices to make closed captioning as accurate as possible.

• Speak clearly, slowly, and directly into the microphone. The further you are from the mic, the less accurate the CC is.
• Avoid areas with loud background noise.
• Avoid having multiple people speaking at the same time.

Notes:

Live transcription currently only supports English and the accuracy of the feature depends on many variables, such as but not limited to:

• Speaker's proficiency with the English language
• Lexicons and dialects specific to a geography or community
