p Tube Vocal Tract

version 1.4 (2.02 MB) by

This exercise computes the frequency response of a p-tube model of a human vocal tract.



View License

This MATLAB exercise computes and plots the impulse response and the log magnitude spectrum (along with the locations of the formants) for a uniform length p-tube model of the vocal tract by explicitly exciting the flow diagram of the p-tube model with a forward-going impulse, and then solving the nodal equations for the forward and backward signals at each node and for each instant of time. The p-tube model impulse response is convolved with a periodic glottal excitation, thereby allowing the user to listen to the resulting vowel sound produced by the p-tube model.
