The presentation concerns a method of wavemorphing applied to a model of the phonatory excitation, the instantaneous frequency and the harmonic richness of which are controlled. This method is based on an interpolation between the Fourier coefficients of two template waveforms. The method enables morphing continuously from one waveshape to another. Possible applications are the simulation of diplophonia, biphonation and different phonation types.
