You need to have a time pointer that is reading through the analysis file.

for example,
I have a file, guitararch.aiff, which is about 5 and 1/2 seconds long.
I made the .pvc file and placed it in my folder.

in my instr I'd have

ktimpnt   line 4, p3, 5.32

(this should make a pointer through the file that lasts the duration
of the note event. I start a little late and end a little early to
prevent the pvoc from complaining that it has reached the end of the
file, which seems to slow down the rendering speed a lot.)
then input this into

ap  pvoc ktimpnt, kfmod, "guitararch.pvc", 0

with whatever kfmod (pitch alteration) you want.
kfmod = 1, earlier in your orc would make it no pitch change.

you can change around the type of ktimpnt how ever you want, make it
exponential, or use segments to go back and forth over the same piece
of the audio, it's really flexible, but you need to have it moving
somewhere or there will be no sound.

Pvoc seems to be less supported now though, and others on the list
have been recommending using other opcodes like pvsyth
