Abstract

A method and system are provided for correcting a pitch of a human generated vocal signal. A human vocal signal is received at a first input. A reference signal having correct pitch is received at a second input. The pitch of the human vocal signal is then corrected by shifting the pitch of the human vocal signal to match the pitch of the reference signal, e.g., using pitch shifter circuitry.
