Voice Input for Programing 📺 (year 2013)

A very cool video. Using voice to code, and code faster than average programer with keyboard. It's a presentation at Python Conference 2013.

The first demo, voice coding emacs lisp, starts at 09:00.


Two years ago I developed a case of Emacs Pinkie (RSI) so severe my hands went numb and I could no longer type or work. Desperate, I tried voice recognition. At first programming with it was painfully slow but, as I couldn't type, I persevered. After several months of vocab tweaking and duct-tape coding in Python and Emacs Lisp, I had a system that enabled me to code faster and more efficiently by voice than I ever had by hand.

In a fast-paced live demo, I will create a small system using Python, plus a few other languages for good measure, and deploy it without touching the keyboard. The demo gods will make a scheduled appearance. I hope to convince you that voice recognition is no longer a crutch for the disabled or limited to plain prose. It's now a highly effective tool that could benefit all programmers.

if you are impatient, here's a summary of the video:

The expensive microphone he recommended is “Audix OM-7 Microphone”

I've used Microsoft speech recognition system, for a few months in 2010. It comes with Microsoft Windows 7. It's pretty good for normal speech but impossible for coding (out of the box). It works well in normal Windows apps, especially ones from Microsoft such as Office, but doesn't work well in emacs.
