A new noniterative algorithm for computing acoustically constrained vocal tract area functions
J. DeLucia, F. Kochman · IEEE Transactions on Speech and Audio Processing · 2000
We describe a new noniterative algorithm for generating the unique area function determined by the vocal tract length, the lip radius, and the spectral pair consisting of poles of the transfer function and zeros of the input impedance function. Our analysis is restricted to the class of piecewise-constant area functions defined on an even number of equal length intervals. The resulting algorithm involves fewer floating point operations per evaluation than the analogous method of Paige and Zue (1970).
