Experimental Determination of the Area Function of a Lossy, Dynamically Varying Vocal Tract
M. M. Sondhi · The Journal of the Acoustical Society of America · 1973
During the last year we have made acoustic impulse-response measurements at the lips while the vocal tract is moved as in normal speech. The experiment will be described and moves will be shown of the area functions reconstructed from the measurements. A method will be presented for estimating the mechanical impedance of the walls of the vocal tract. It will be shown that the reconstructed areas are significantly improved if the walls, instead of being assumed rigid, are assumed to have this estimated impedance.
