[gnuspeech-contact] Question regarding sensitivity functions

[Francesco DEste]

Dear Gnuspeech Contact Mailing List,
I am a student at the Leiden University, currently developing a thesis in  Vocal Tract Area
Function  estimation. 
I am using the gnuspeech tube waveguide software embedded in an Multi-Objective optimization software.
The method I implemented uses a MO-Evolutionary algorithm to try to match
a target sound.

I would like to ask a couple of informations regarding the Distinctive Region Model
and the sensitivity function calculation.
Given an arbitrary posture, is it possible to calculate its sensitivity function efficiently?
From what I understood, the table shown in the documentation (R1-R8 against F1-F3)
works only when the tube is on a 'close to straight' configuration.

Since the sensitivity is a function of the volume velocity and pressure, is there a way
to keep track of this data inside the tube routines?

If it would be possible, I would like to incorporate this knowledge inside the evolutionary
operators of my system.

Many thanks for the attention,
with kind regards.
Francesco D'Este
