Your use of Whisper models on-device for macOS aligns well with the goals of speech-swift (which I maintain), offering robust integration with CoreML for ASR and TTS. It could serve as an alternative with its native Swift async support on Apple Silicon. Explore more here: https://github.com/soniqo/speech-swift

I just had a look at some of your youtube videos. It looks awesome, I will definitely take a look at using it. I've been thinking about how I can support other local models in the future - I think this would make a lot of sense for the ASR in my app. Do you have any realtime ASR examples of speech-swift that I could look at?
