     http://soundlab.cs.princeton.edu/software/rt_lpc/

is a small real-time LPC analysis/synthesis application and 
visualization.
Currently, it allows pitch transformations (of the glottal pulses) and 
it is
also possible to "sing" with it using a MIDI controller for the pitch.  
It also
comes with a library in C that performs Nth order LPC analysis and
synthesis.  Transformations, such as formant shifting, can be added in
the middle (e.g. moving the poles of the LPC filter).  this library/app 
and
LPC probably doesn't do everything you want, but may be a good starting
point.

Best,
Ge!
