ABSTRACT:
A method of changing psychological stress indices by evaluating manifestations of physiological change in the human voice wherein the utterances of a subject under examination are formatted as electrical signals and processed to alter selected characteristics which have been found to change with psycho-physiological state changes, such that the resultant output data signals are perceptually unchanged yet display none of the undesired physiological response characteristics. Apparatus for performing changes of this type includes a data input port, means for spectral alteration and a data output port.
