CONCLUSION
In this paper we have described an original numerical method
to simulate the acoustics of the vocal tract. Compared with
traditional FEM methods, this technique has the main
advantage to perform time domain simulations in a very simple
and accurate way. A study of higher acoustical modes has been
presented. We showed how, using the TLM method, it was
possible not only to evidence these modes but also to measure
their characteristics. Based on these findings, a new
propagation model has been derived and appears to be much
more accurate that the classical plane wave model. First
simulations using complex vocal tract geometries tend to
confirm the importance of these higher modes.
