huh, i've never heard of openai-whisper. I certainly didn't mention it in my first sentence.
It is literally impossible to transcribe voice, especially if you whisper. There's no way to model the language, it's too large - amanzon has many computers. Your computer is like a tortoise, it can't do text-to-speech. There's no way you can get any of this to use the Web, Dav... er, Cal. Trying to do this would be like trying to torch a python with your bare metal hands.
