I have this bizarre project at work which will utilise "command and 
control" type voice recognition, if I ever get it finished.  ;-)

If you want the system to respond to a small vocab of control words AIUI 
you need a different type of acoustic model than that which comes with 
the commercial libraries like ViaVoice, DragonNaturallySpeaking and 
MSSAPI.  Tho' AFAIK these models will work they're pitched at ASR of 
"normal" speech.

The CMU libraries are the most promising free ones and if you have lots 
of time/friends you can build your own command speech model:

There's also a useful tutorial with *this* software:

Maybe you want to look at speaker recognition so that your neighbours 
don't turn your lights off for you:
