Abstract
The invention concerns a method () and system () for improving voice quality of a vocoder (). The method includes the steps of monitoring () a pitch of a voice signal () at a transmitting unit (); when the pitch of the voice signal reaches a predetermined threshold (), shifting () the pitch of the voice signal to at least a portion of a predetermined range (); transmitting () the pitch-shifted voice signal to a receiving unit (); and at the receiving unit, reshifting () the pitch-shifted voice signal to a level that compensates the step of shifting the pitch of the voice signal at the transmitting unit.
