Keyboard voice commands

[soupslurpr]

Voice commands to control the keyboard. Maybe at first just try to implement commands for deletion and punctuation, with future commands in mind when figuring out what the specific command for each of those will be.

Not sure of the specific approach that should be followed for this, it likely needs some trial and error to figure out. It may need some lower level code that interfaces with the model while it's generating or something like that. If so, it will be blocked until the speech to text is switched to a Rust implementation.
