Hey there!
This is a job for Handy. I recently started using it with the Parakeet recommended model. It works very very well. Whisper packaged with Wyoming that I run is pretty much unusable for dutch but Parakeet in Handy seems to work quite well. Direct input of text into whatever program you want. Downloads a small local model and works only on your computer. Push-to-talk or toggle, tons of customizations.
Note that this just speech to text and the models aren't made for post processing. So it will dictate exactly what you say, umms and everything. If you want cleanup, formatting, etc... Then you have to rely on a much more general model, but the makers are experimenting with an opt-in for that for various external AIs.
