Abstract
A voice encoder for use in low bit rate vocoding applications employs a method of encoding a plurality of digital information frames. This method includes the step of providing an estimate of the digital information frame, which estimate includes a frame shape characteristic. Further, a fundamental frequency associated with the digital information frame is identified and used to establish a shape window. Lastly, the frame shape characteristic is matched, within the shape window, with a predetermined shape function to produce a plurality of shape parameters.
