None. The LP source-filter model is only phenomenological and cannot
be decomposed into models of the bodily contributors to voice
production. In particular the vocal folds do not produce a pure
impulse train, so a first step toward physiological correspondence
could be to record the actual excitation with a thorax microphone and
deconvolve the sound signal with that for the vocal tract response,
though this still leaves both parts as black boxes. For an example of
deeper modeling see:

This is a specific system. But in DSP point of view, you got to find
feed back loop in the counterpart system.

H(z) = G/(1-sum(ak*z.^ -k)) .
It is -k,not k.

The all pole model is as follows.
H(z) = G/(1-sum(ak*z.^k))
where, a is the lpc coefficients.
The physiological digital model is : exitation system + vocal tract
system + radiation system.

We can attain the all pole system function of speech from linear
prediction(LP). But how to correspond it with the digital model in
physiological sense?
Where can i download such literature discussing the relation between
them in detail?
questions: 1. what is the counterpart of the lpc all pole model in
physiological sense?
2. what is the counterpart of the input of lpc all pole
model then?
