A generalized acoustic tube model of the vocal tract is considered, relating it to pole-zero-type linear prediction. The generalization is done by including the nasal cavity for the modeling, thus forming a three-branched model. The transfer function is obtained from the generalized model by conglomerating one of the three branches to the branch section at the junction of the three branches. It is also shown how to find coefficients for pole-zero-type linear prediction from the voiced sounds, and how to evaluate the reflection coefficients by connecting the prediction algorithm to the transfer function of the generalized model.
