Description: 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.

Description: 2.4 kbps MELP Proposed Federal Standard speech coder
Fixed-point C code, version 1.0
The fixed-point version of the voice codec Mixed Excitation Linear
Prediction (MELP) is based on specifications on the C-language software
simulation contained in GSM 06.06 This standard is available from the ETSI publication office
Department of Defense to use the C-language software simulation contained
in GSM 06.06 for the purposes of the development of a fixed-point
version of the voice codec Mixed Excitation Linear Prediction (MELP).

Description: 提出了一种新的工作于极低码率下的混合激励线性预测(MELP)声码器.该声码器结合了线性预测编码(LPC)和多带激励编码算法的优点,对算法和量化方案重新进行了设计和改造,其主要特征包括改进的基音检测算法、混合的周期脉冲和随机噪声激励、有效的线性谱频率(LSF)参数量化以及激励谱形状表示.非正式主观测试表明,由采用本算法的一个2.4 kb/s编码器所重建的语音质量略优于美国联邦标准4.8 kb/s码激励线性预测编码(CELP)所重建的语音质量.-New Mixed Excitation Linear Prediction Codec at 2.4 kb/s

Description: 为了提高深度模型的编码重构性能,本文为传统对比散度(Contrastive divergence,CD)添加了基于交叉熵的重构误差约束。利用改进后的算法训练了重构性深度自编码机(Reconstructive deep au-to-encoder,RDAE),并用 RDAE 替换混合激励线性预测编码(Mixed excitation linear prediction, MELP)语音编码器中 LSF 参数的矢量量化方法。测试结果表明,改进后的算法在损失一定模型似然度的条件下获得了重构性能的提升,当 RDAE 隐藏层结点设为19 bit 时,本文方法所测得的加权 LSF 距离、重构语音质量、谱失真指标在训练集和测试集上均优于25 bit 矢量量化方法,即利用本文方法改进的 MELP 编码器,在不降低语音质量的条件下,可将 MELP 编码速率从2.4 kb/s 降低至2.1 kb/s,编码速率降低了12.5 。-Improved MELP Algorithm Based on Reconstructive Deep Neural Network
