Not an area I'm that familiar with, but are there any good libraries out there

The formant analysis code from snack
http://www.speech.kth.se/snack/
is the code from the well known ESPS package and most praised in the speech

CMU Sphinx (Java) uses Cepstra for recognition.
That's the Fourier transform of the log-magnitude spectrum:
fFt(ln( | fFt(window . signal) | ))
