If cost isn’t an issue, I’d use one of the established commercial offerings. Otherwise, you could try splitting into shorter chunks (20 minutes maybe?), do multiple runs on each chunk and pick out the best run according to some criteria, e.g. character count after removing repetitions. Whisper isn’t deterministic so some runs can be better than others; you could also tweak parameters like compression ratio or silence thresholds between runs, but in my experience there’s not going to be an obvious winner leading to a marked improvement in quality. Anyway, I’m no expert, and maybe you’ll have better luck than me. My recordings do have background music and conversations in some places that might confuse the model.

Can't use third party service -- compliance stuff. This is helpful though. Using another model to tidy it up -- maybe Alpaca -- could be an option too. Then we'll just do speaker separation etc. manually later.
