Study by simulation of the acoustic characteristics of the vocal tract with losses

H. Teffahi, B. Guerin, A. Djeradi


Wave propagation in a lossy vocal-tract with yielding walls is studied. Simulation method of this vocal-tract is described. The method adopted allowed us to calculate the transfer function, the formant frequencies and the formant bandwidths of the vocal-tract. The results obtained permit the determination of the differential contribution of the different loss sources for formant frequencies and formant bandwidths.
