A reflectance formulation of the acoustic inverse-scattering method of measuring vocal tract area functions has been developed. We arrive at a partial differential difference equation in which the pressure and area of the vocal tract appear as unknown functions. Such a formulation has several advantages. First, the vocal tract model may include a spatially dependent loss term whose magnitude need not be proportional to area. Second, the solution of the equation evolves in space and time, thereby leading to a recursive computational procedure. The relationship between this approach and the integral equation method in the lossless case is developed in terms of the Riemann function for the underlying Webster equation.
