本文提出了一种利用MBE 模型改进的低速率LPC 语音编码算法文中介绍了该算法
的参数提取量化编码及语音合成的具体方案并用C 语言构造了一个基于该算法的速率
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.
