Abstract:
In this paper, we present the development of the matrix
condensation and the Transfer Matrix techniques and their
implementation into Finite Element Method (FEM) for the vocal
tract modeling. These techniques need small computer CPU memory
and shorter computing time comparing with the standard FEM. A new
technique to compute the multi-port model of impedance functions
for parts of the vocal tract has been developed too. Using this
model, the effect of each part of the vocal tract cross-sections
on the propagation of the acoustic waves will be shown. It makes
also the computing of the transfer function and other acoustical
characteristics easier to obtain with one simulation using
various boundary conditions.
