Think around, not through. What we want is efficient, intuitive and reliable human computer communication. If voice recognition is that hard, with many facepalm inducing errors, it is a stupid way to go. It is easier for humans to adapt to the machine. This means artificial dialects and simple AI and a bit of human training. Human consumers are lazy and want magic. Apple and MS try to grab them with the illusion of magic. It would be better for the free software to research what changes to speaking habits make the software component easier, then write howtos and youtube guides as to how to speak to it.
Reminds me of the Palm Pilot and Graffiti. Rather than try to recognize normal handwriting like Microsoft was doing, Jeff Hawkins designed a simplified single stroke character representation that was very to recognize in software.
