Simulation of human vocal tract model is necessary to understand the effect of different conditions on speech generation.In natural calamities such as earthquakes person may swallow soil due to large amount of dust around.The effect of soil is investigated on the sound pressure in the human vocal tract.The generation of speech starts from the glottis, so the soil obstacle is positioned near it.The whole model is designed and analyzed using FEM.As the speech signal requires a bandwidth near about 4 kHz, the investigation carried out to obtained sound pressure in the human vocal tract from 100-5000 Hz sound signals.
