I'm doing something extremely similar. Did anyone get any results?

Hi everyone, I'm trying to convert wav file to a text or a pfs file and I think Pure Data is a pretty software to start with. Is there any way in Pure Data to convert a wav file to a text/pfs file in terms first/second formant frequencies and amplitudes and the frequency of the voice pitch. Thanks.

How can I measure the voiced and unvoiced segment duration of an input?
