Numerical simulation of pronunciation of vowels based on FE models of human supraglottal acoustic spaces

Aproximate finite element models of acoustic spaces corresponding to the human vocal tract for English vowels /a/ and /i/, created according to the geometrical data published in the literature, are used for the numerical simulations. The pronunciation of the vowels /a/ and /i/ is simulated using transient analysis for the FE models. The pulse excitation of the vocal tract is realised by the time dependent displacement of a small circular plate moving at the position of the vocal folds
