Closed captioning can usually be activated during live video on Google Meet. Both the teacher and student will have to turn on this feature.
Many videos can be closed-captioned from the viewer's end using webcaptioner.com.
Tactiq is a free Google Chrome extension that transcribes Google Meet video, if closed captioning is turned on. At the end of the live lesson, click on the Tactiq icon, add to clipboard, and paste into a document for sharing. For more information, go to https://www.youtube.com/watch?v=i40WUrSCIa8
