I didn't get to fix it yesterday when I got into San Francisco either because I ended up going to Maker Faire and then hung out at a bar with all the Hackaday people. I met the guy who invented sudo and figured out I have the same watch as Mike Szczys.
Anyways, I've fixed voicecommand to work again and I fixed a couple of small bugs, including one in the install script which didn't copy the voicecommand config properly.
To get the fix, just run the update script (or reinstall if you are having config file issues).
I detailed how to update here:

Here's a picture from Maker Faire for your trouble!
