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.
