The high number of elements in the FE models was reduced by introducing acoustic superelements. a novel algorithm for parameterization of the FE models was derived to allow modifying and tuning the model shape according to prescribed acoustic characteristics of the vocal tract. The sound radiation losses at the lips and sound absorption at the vocal tract walls were taken into account. The frequency modal characteristics of the three-dimensional (3D) and one-dimensional (1D) vocal tract models were compared. The results showed that the 1D models can closely replicate the behavior of the 3D vocal tract up to 3000Hz.
