A wideband CELP speech coder at 16 kbit/s based on mel-generalized cepstral analysis
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181)
This paper proposes a wideband CELP coder using frequency warping. Instead of linear prediction, the proposed coder adopts the melgeneralized cepstral analysis, and encodes fullband of the speech signal through a warped frequency scale. It is shown that the subjective quality of the proposed coder at 16 kbit/s is better than that of the ITU-T G.722 at 64 kbit/s. Furthermore, the proposed coder gives a much smaller difference in performance for male and female speakers than the conventional CELPdoi:10.1109/icassp.1998.674392 dblp:conf/icassp/KoishidaHTK98 fatcat:nujgokvow5emhgkqvov3g3jlxa
