Hi CR,
Sorry for the inconvenience caused, I understand the issue has affected your daily work.
When I test from my side in Word for web, I can reproduce that the Transcribe option disappears from the ribbon in Edge(version 90.0.818.42) and Chrome browser(version 90.0.4430.72).
I have ensured that the editing language is set to en-US and "Enable optional connected experiences" is enabled via File>About>Privacy Settings in Word for the web. When I try to search Transcribe option, it shows grayed out.
Update:
The issue has been fixed. Transcribe feature is working now.
I would like to make a summary for the issue below so that other community members can easily find the information:
