Taking the assumption that you are interested in learning and
evaluation, and given you state you need a basic voice recognition
system, could I suggest an inexpensive way could be to use the
dsPIC30F speech recognition library (Evaluation version is available
for $5). With a few inexpensive suitable demonstration boards
available (dsPICDEM),
