I created Kaldi Active Grammar because I didn't trust relying on closed source software for something so crucial to my productivity, where a decision by an outside party determines whether I can function. As a bonus, open source means I can make it work better to fit my needs than closed source ever could.
Furthermore, the original article mentions Caster (which is built on Dragonfly), but doesn't mention that KaldiAG works with it, and that work is underway to expand Caster's platform support.
I found your measurement here [1] which is against an unknown wav2letter acoustic+language model pair, as the web demo is at any given point in time running an arbitrary model based on having users test in-progress models, and it has never been running the model I am currently shipping with Talon.
(As a small example, the unfinished wav2letter experiment I am training right now has a 3.17% WER on speech commands, and 6.86% WER on librispeech clean, both numbers without using a language model)

Fun tidbit: Most of the commands I use in vim are just the Talon alphabet.
(For example, I suspect the microphone their school supplies them with may be no good)
Also, Dragon has many commands that cannot be disabled, and if your accuracy is already low, more commands available means more possible things to get wrong. Something like Dragonfly with KaldiAG could allow you to reduce the command set, and improve the practical accuracy.
So, more personalized training/software may work better.
I've been waiting to try Talon for ages - glad I can give it a try now.
There are at least two cross-platform projects where the biggest expense is a microphone instead of software.
1. My project, Talon. Windows/Linux/Mac support, and a first party local speech recognition engine that is pretty good and getting better. It’s free, but the engine is in a private beta (which is $15/mo to support development, optional if there’s a financial issue).
2. Serenade. They are VC backed. Currently free, unsure about their longer term plans. They use cloud based recognition.
