From the developer:
The Voice Tweaker plug-in is a harmonic pitch transposer designed for monophonic signals such as voice, spoken or sung, or solo instruments. It can transpose the pitch and formants independently, thus enabling both formant preserving pitch transpose and other more unusual effects. The Voice Tweaker also features an automatic pitch correction function and auto vibrato.
