[PD] whisper filtering and fft

I'm attempting to create whisper-like effects using cascading and parallel filtering of noise. Does anyone have some filters that they would recommend or point me towards. I'm pretty sure that this would be the same type of filtering associated with speech related formants. I'm also interested in filter settings that will replicate most vowels/phonemes.

Is there a good resource that explains how PD's FFT works with some explanation of the theory and applications. The help files just don't explain enough and I don't have enough of a background in FFT as of yet to figure out meaningful manipulations or applications of the data.

Thanks, Phil
