为1.6kb/s 的语音编码/解码系统主观测听表明该系统性能与2.4kb/s 的MELP 算法接近

或相当-In this paper, a LPC algorithm in low bit rate speech coding improved by MBE model

is presented. The detailed schemes of parameter extraction, quantization, coding, and speech

synthesis are introduced. In addition, a 1.6kb/s speech coding/decoding system based on this

algorithm is constructed with language C. By subjective evaluation, it is concluded that the

performance of this system approaches or corresponds to that of 2.4kb/s MELP algorithm.
