I just tried the OpenVINO transcription on a random speech-over-music mp3 I happened to have: it works great, FAR better quality than I expected (I think I was expecting Youtube quality, but this is much cleaner and clearer). Perfect capitalization, good sentence breaks, adequate punctuation (commas, periods, question marks).
Only problem is that I can't figure out how to copy the transcription so I can paste it outside Audacity: the transcriptions show up attached to specific portions of sound, like track labels. While it will save me the trouble of having to actually transcribe audio manually, to get them out of Audacity and into a word processor it looks like I may still be stuck copying each "label" individually unless I can find a way to copy or export them.
EDITED TO ADD: I just answered my own question, lol. File -> Export Other -> Export Labels -> .txt file
