[PD] consonant extraction using fft

[Pedro Lopes]

I recently heard a seminar by a researcher called Gopala Anumanchipalli[1],
here in Portugal.
He works around similar subjects (modelling and extracting pronunciation via
signal processing - and in order to to that I think he extracts consonants
and vowels), take a look at his homepage maybe there's something there.

Best regards,
Pedro
p.s.: maybe a too long shot. but what the heck. :)
