Comparison of computed and measured acoustic characteristics of an artificially lengthened vocal tract
Original language description
The First formant frequency F1 of a human vocal tract (VT) prolonged with a glass tube was measured for a VT model with solid walls and a real human VT, and the results were compared to a mathematical model. The experiments with the VT model confirmed the legitimacy of an assumption of the solid walls in the mathematical simulations of acoustical characteristics of the artificial VT plexiglass model prolonged with the tube. The measured F1=73 Hz well corresponded to the computed value 78 Hz. However, the in vivo experiments in human, performed in a similar way, showed a much higher value of F1 at about 200 Hz, that is caused by soft tissues on the walls of real human VT cavities.
