Originální abstrakt
The paper presents a 3D finite element (FE) model of propagation of acoustic waves from vocal folds through the vocal tract and around human head during speech production. Computer tomography (CT) images taken during phonation of the subject were used to create geometrical model of the acoustic spaces corresponding to the human vocal tract and the acoustic spaces around the human head. Modal and harmonic analyses (harmonic excitation at the position of the vocal folds) were used for determination of the resonant characteristics of the FE model. The results of numerical simulations are in good agreement with the experimental data known from literature. The developed model allows evaluating acoustic pressures at any point inside the vocal tract and in the space around the head and can be used for analysis of the sound field around the human head during speech production.
