Push to talk: How to Configure?

[quicksketch]

Hi @ideasman42, fantastic project and I got it up and running in less than an hour, including some basic scripting.

Both in the README and in some other issues (#39 (comment)) you've describe setting up nerd-dictate with "push to talk". Could you describe how to set that up?

Using a Ubuntu Keyboard Shortcut (Settings -> Keyboard -> View and Customize Shortcuts -> Custom Shortcuts), I made a shortcut for "Start Dictation" that executes nerd-dictation begin &. Great. Now I can start dictation using the shortcut.

What I'd like to do however is to either:

A) Hit the key once to start, and hit it again to stop (I was thinking of hijacking caps-lock for this purpose). Or:
B) Hold and press the key to start, and stop when I lift up.

I figured I could probably write a script that checks the running processes with ps -A | grep parec and then toggle the command to be nerd-dictate start & or nerd-dictate end, and that would allow me to do option A. But I am stuck on how I could do option B. Could you suggest a way to accomplish this?

What I do is set keyboard shortcut Ctrl-B to run a shell script to start nerd dictation, and Ctrl-E to end it. You could also bind them to Scroll Lock and Ctrl-Scroll Lock.

My scripts: ndb.sh:

#!/usr/bin/bash
cd /home/beng/apps/nerd-dictation/
./nerd-dictation begin --vosk-model-dir=./model --numbers-as-digits

nde.sh:

#!/usr/bin/bash
cd /home/beng/apps/nerd-dictation/
./nerd-dictation end
