It won't.

I'm still not sure I fully understand all you are scheming.
However, I can confidently say that the audio sound of the
letter "p", as it shows up in any word, will NOT "translate"
to the same pattern of numbers every time - even if it is only
one person saying the words.  Speech is just too complex.  

If you do precision gain matching, and the person talks slowly
and clearly, and you do statistical analysis on the numbers,
you might be able to determine that a particular set of
numbers is has a high probability of being a "p".

What I think you are trying to do is build a transcription
tool, or speech recognition.  SoX can process the audio for
you - but if you are hoping a simple pattern matching will be
able to identify all the letters associated with the sounds,
it won't work.  Speech is just too complex. :)

There are a few very mature projects working on speech
recognition and/or transcription.  Maybe you should look at
some of the challenges they have dealt with to give you a
better idea of the task.
