Is there a reason not to use built in macOS transcribing? Genuinely curious what the goal is here, though points given for coolness factor.
The issue I have with the macOS transcribing is that it can never do things like learn slang, change the punctuation based on the input box, filter filler words, etc... It does work and it's primarily what I use on mobile but I just wanted to go a different direction here.
One thing I wanted to do with this project (which I likely won't do) is make it so you can tell it a set of instructions like "Go to Slack and send Tom a Direct message saying that I am going to be 5 minutes late" and it would be able to do that. That's really close to the behavior of Siri but I thought that might be neat.
