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:

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?
