A waveform adaptive physical model of the glottal source is proposed. The model
relies on a lumped mechano aerodynamic schema loosely inspired to the oneand
two-mass lumped models. The vocal folds are represented by a single mechanical
resonator and a propagation line which takes into account the vertical
phase differences. The vocal folds displacement is coupled to the glottal flow
by means of an aerodynamic driving block which includes a general parametric
nonlinear component. The principal characteristics of the flow-induced oscillations are retained, and the overall model is able to adapt to glottal flow signals with different characteristics.
