The 3D FE models of the nasal cavities and adult female vocal tract were developed from computer tomography (CT) images for vowels /a:/ and /i:/. The interconnections between the oral and nasal cavities were created according to the anatomical literature. The acoustic frequency - modal characteristics of the FE models were studied by the modal analysis considering zero pressure at the lips and nose and the influence of velopharyngeal insufficiency on the first ten formants was evaluated.
