We propose a computational method for time-varying spectra based on 3-D vocal tract shape using Finite Element Method (FEM). In order to obtain the time-varying spectra, we introduce auto-mesh algorithm and interpolation. We show the vocal tract transfer function (VTTF) with variable shape continuously.
