I'm impressed you managed to do that on an 8-bit microcontroller! Free software for speech recognition has been slow to develop in the past. Now there are a couple: http://freshmeat.net/search/?q=speech+recognition§ion=projects&Go.x=0&Go.y=0 E.g. there is Sphinx and Julius, and there is also an HMM toolkit which might be useful (or not). Do you expect to achieve better performance than those?
