I don't know if it meets your needs, but I use MacWhisper (Pro) for this. I was an early Pro user so I think I only paid $5 at the time.
I’ve also encountered some bugs. While debugging, I found that many stem from Apple’s platform itself (not MacWhisper) particularly around Metal and arbitrary object resource limits.
I can always feel hte MacWhisper bugs about to come on when you start to see little glitches like document icon previews in the Dock not rendering or screenshot utility not rendering the screenshot preview, brief flashes of magenta or green when resizing windows.
