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. :)

Hi all,
I have been playing with fft lately and was wondering if anyone has some pointers on how to extract consonants from vowels in human speech. I suspect it is detection of noisy signal that generally populates a much wider band of frequencies approaching some sort of filtered white noise (depending on the consonant) but am not sure as to what is the best strategy in isolating these at least somewhat reliably.
Any ideas/pointers would be most appreciated.
