Tavis Rudd describes how RSI forced him to program by voice, and shows the Python and Emacs Lisp system he built with voice recognition. A live demo creates and deploys a small system without touching the keyboard.
Recurs in threads about RSI, accessibility and voice coding as the go-to demo of a custom spoken command language.

> The second thing we need to figure out is how we can compress voice input to make it faster to transmit. What’s the voice equivalent of a thumbs-up or a keyboard shortcut? Can I prompt Claude faster with simple sounds and whistles? This reminds me of the amazing 2013 video of Travis Rudd coding python by voice: this video The number of times in the last few years I've wanted that level of "verbal hotkeys"... The latencies of many coding llms are still a little bit too low to allow for my ideal level of flow (though admittedly I haven't tried one's hosted on services like groq), but I can clearly envision a time when I'm issuing tight commands to a coder model that's chatting with me and watching my program evolve on screen in real time. On a somewhat related note to conversational interfaces, the other day I wanted to study some first aid stuff - used Gemini to read the whole textbook and generate Anki flash cards, then copied and pasted the flashcards directly into chat GPT voice mode and had it quiz me. That was probably the most miraculous experience of voice interface I've had in a long time - I could do chores while being constantly quizzed on what I wanted to learn, and anytime I had a question or comment I could just ask it to explain or expound on a term or tangent.
I'm surprised that there seem to be no examples anywhere of anyone seriously using chorded typing for programming. After cheap chorded keyboards entered the market and the associated software became free, I assumed it would only be a matter of time before something like Travis Rudd's incredible demo of voice coding [1] came out. Perhaps that it hasn't speaks to how difficult it is to get real speed improvements with a chorded setup? [1] this video
Maybe lisp could shine here? While writing lisp code in classic editors, you already shouldn't be editing or navigating code with classic commands, instead you will be using structured editing. Of course it isn't limited to lisp, but languages with C-like syntax are harder to use for structured editing. I highly recommend watching this video, where the speaker uses voice commands to write both in emacs-lisp and in python. this video
A similar project using Emacs and really clever use of Python and Dragon Naturally Speaking SDK was my favorite presentation at PyCon this past year. this video
Tavis Rudd's Using Python to Code by Voice [0] is also interesting. Looking up that URL, I came across the more recent Coding by Voice with Dragonfly [1]. Haven't seen that one yet, but just quickly skimmed through. Unfortunately the live demos are silent (you can't hear speaker Boudewijn Aasman talk to the computer), but it seems worth checking out if you're interested in setting up some recent voice recognition software with your own custom voice command syntax.
