Hi,
I do realise it’s been years since you posted this plugin idea but was wondering whether the tool I builf for my own use first and then shared here would fit your use case. Transcription options have made a huge leap in terms of speed and quality recently. And since it is an obsidian plugin it shouldn’t matter what operating system you’re on.
If you think it fits your use case - still 
and would like to try it feel free - I would really appreciate it - any help testing and providing feedback is welcome!
You can find more information here and install using BRAT: Voxtral Transcribe — dictate and type at the same time into your notes with voice commands (beta testers wanted!)
Kind regards,
Max
