Abstract :
The contribution of high-frequency zeros to the glottal-vocal-tract spectrum can be represented in the z plane by a negative-real-axis zero of high multiplicity. Analytically derived results for the location and order of the compensating zero are in agreement with those obtained by a numerical curve-fitting procedure using a digital computer.
