In this paper, we consider a method for estimating the vocal-tract area function from given formant frequencies. A sensitivity function is used to represent the amount of change in the formant frequency due to small perturbations of the vocal-tract area. The method is an extension of the study of B. H. Story (J.A.S.A., 119, 715-718, 1996). We also examine the estimation of the vocal-tract length expressed as a dependent variable of the vocal tract area. Numerical results show that our method can jointly estimate the length and sectional area of the vocal-tract while maintaining the accuracy of the previous method for the area estimation. |
