Summary: The inverse scattering problem is reviewed for determining the cross sectional area of a human vocal track. Various data sets are examined resulting from a unit-amplitude, monochromatic, sinusoidal volume velocity sent from the glottis towards the lips. In case of nonuniqueness from a given data set, additional information is indicated for the unique recovery.
