Solution 1

Voice recognition requires some kind of transform either Fourier or Wavelet to come to a short numerical representation of the speakers voice. You would want to compare that to a stored command template not the actual WAV input.

Check the following article : Speech Recognition[^]

What do you mean with "compare"? Do you want:
a) compare the words I'm saying with the words that have been said before or
b) compare my voice characteristic with the one you know to be sure I'm the same person?

If the problem is a) what you need is to translate all voices int otext and compare text. Comparing the sound waves is clueless: whatever you may say and repeat, is never the same wave. What you hear (or better, what your brain interprets) is the variation of the spectrum, not the direct floating of the air.
