本论文在对melp编码算法进行分析的基础上，提出了用软件实现语音信号编解码的方案；然后，基于melp标准，开发了仿真系统，实现对语音信号的编解码。 - Melp which can work at the rate of 2 . 4kb / s has been chosen as u . s . federal standard , melp algorithm is on the basis of line prediction ( lp ) . five auxiliary characters has been introduced into melp algorithm , they are mixed excitation , aperiodic pulse , fourier magnitudes pulse dispersion and adaptive spectral filtering
作为一种重要的低速率语音编码算法,美国联邦标准melp算法对lpc - 10编码方案做了大量改进,引入了混合激励,非周期脉冲,残差付氏幅度谱,脉冲散布和自适应谱滤波五个附加特征,在2 . 4kbit / s的速率下取得了比较自然的语音质量。 - Melp vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional lpc vocoders , and add a jitter voicing state to overcome the tonal noise . parameters " interpolation , adaptive spectrum enhancement and pulse dispersion also are adopted to improve the continuity . the synthetic speech of melp vocoders sound much more natural and perceivable than the traditional vocoders "
Melp声码器采用混合脉冲和噪声激励解决了经典lpc的嗡嗡声的问题；引入了抖动浊音状态以克服音调噪声；利用参数插值、脉冲散布和自适应谱增强等措施提高合成语音的自然度和可懂度；此外还采用了多带激励，使其具有了比较强的抗背景噪声的性能。
