Is Whisper really up to this? When I've used it, it's...fine. But it also randomly dreams up weird transcriptions that have nothing to do with what's actually being said, and with perfect audio too. Like the audio will be a presentation at a tech conference, and Whisper will predict "check out our site at randomlink.com", when no one said anything close to that. I'd be pretty concerned if my doctor relied on this to be honest.
