ABSTRACT:
The invention addresses the problem of undesirble emotional states in general, and during the performance of public speaking in particular. The user of the invention wears a microphone and earphones. The invention digitally alters how the user hears his or her voice, to sound as if the user is in a different emotional state. The user may choose preprogrammed emotional states such as confident authority or happy enthusiasm. The degree of the emotion may also be selected. The result is that the user's emotional state is altered when he or she speaks.
