12. A system for voice transformation comprising: a processor; a voice transformation component for transforming a source speech of a person using transformation parameters, wherein the transforming comprises modifying the source speech to sound as if the source speech were spoken by a different person; and a steganography component for encoding information on the transformation parameters in an output speech using steganography; wherein the source speech can be reconstructed using the output speech and the information on the transformation parameters.
