You might check out some of Erick Tejkowski's classes. There's one
for drawing waveforms to a canvas that might be of some help.

I'd be much more inclined to render a waveform and do a graphical
comparison.
But maybe because I'm much more familiar with graphical comparisons.
I gather you are not checking for identical waveform matches, but
still, you could use waveform comparison
to compare syllable intensity (pitch) and spacing (timing) simply by
comparing the heights and relative offset of the various peaks and
troughs.

I have a customer asking me to create a program that compares two

one pop or click can render them different in the computer's mind
but I'm
looking to create a threshold algorithm to warn of pitch and timing
differences in the files. Has anyone tried this?
