Verifying a vocal tract model with a closed side-branch
Michel T. T. Jackson, Carol Espy-Wilson, Suzanne Boyce · The Journal of the Acoustical Society of America · 2001
In this article an implementation of a vocal tract model and its validation are described. The model uses a transmission line model to calculate pole and zero frequencies for a vocal tract with a closed side-branch such as a sublingual cavity. In the validation study calculated pole and zero frequencies from the model are compared with frequencies estimated using elementary acoustic formulas for a variety of vocal tract configurations.
