ABSTRACT:
Human voice sounds are modified to produce the effect of a different person speaking. A signal representative of the original voice sounds is separated into a plurality of voice signal components each having a different frequency band. The frequency of at least one voice signal component is shifted and the voice signal components are recombined to produce a modified voice signal representative of the modified but intelligible voice sounds.
