well, this shouldn't be too difficult... AFAIR I used formant tables
parameters for vocal sounds for male, female and children voices
that came with the IRCAM SVP phase vocoder... I just need to dig
my (somewhat dusty) archives... I think that similar tables must be
easily avaiable on the web...

one remark though : I used to get stunning results with a phase vocoder,
but when I used the same settings with a bunch of digital BP filters,
the result was far less impressive... I guess the parametric filters need
to
be very steep, and there might be some special tricks to get this out of
analog filters... but may be I'm wrong, as we have several analog
magicians
on this list...
