LD-CELP speech coding with nonlinear prediction

  title={LD-CELP speech coding with nonlinear prediction},
  author={A. Kumar and Allen Gersho},
  journal={IEEE Signal Processing Letters},
A technique for nonlinear prediction of speech via local linear prediction (LLP) is presented and applied to LD-CELP at 16 kbps. With 18th-order backward adaptive LLP for voiced frames, the hybrid LD-CELP coder gives higher segmental signal-to-noise ratio (SNR) compared to a reference version of the ITU-T G.728 LD-CELP algorithm, which has a 50th-order backward adaptive linear predictor. The computational complexity for LLP analysis is significantly less than that of a conventional one-step… CONTINUE READING
