Abstract
Line spectrum frequencies (LSF´s) uniquely represent the linear predictive coding (LPC) filter of a speech frame. In many vocoders LSF´s are used to encode the LPC parameters. In this paper, an interframe differential coding scheme is presented for the LSF´s. The LSF´s of the current speech frame are predicted by using both the LSF´s of the previous frame and some of the LSF´s of the current frame. Then, the difference resulting from prediction is quantized
