OneNote gets "speech to text" Transcribe
The Transcribe option in OneNote for Windows lets you get a “speech to text” written transcript of either a live recording or an already saved audio file.
It’s an extension of the existing Transcribe feature in Word on the web (in a browser) and works the same way. That’s not entirely a good thing because Microsoft has done nothing to fix annoyances in the current Transcribe.

OneNote’s Transcribe is on the far-right of the Home tab.

There’s also a chapter in Dictation and Read Aloud in Office about Transcribe.
Limitations
Originally Transcribe had a limit of 300 minutes per month but that’s changed.
At the moment there’s no limit on the amount of Transcription done but Microsoft counts the minutes and might apply a limit in future.
Only Microsoft 365 customers get Transcribe except government licence users (GCC/GCC-H/DOD).
Who gets it?
Transcribe is in OneNote desktop for Windows (what Microsoft insists on calling just “OneNote”).
Supported languages
Here’s Microsoft’s list of supported languages.
