20. A system for reconstructing a voice transformation, comprising: a processor; a speech receiver for receiving an input speech, wherein the input speech a source speech of a person which was transformed to sound as if the source speech were spoken by a different person, wherein the output speech comprises encoded information on the transformation parameters using steganography; a steganography decoder component for decoding the information on the transformation parameters from the input speech; and a voice reconstruction component for carrying out an inverse transformation of the input speech to obtain an approximation of the source speech.
