- The last character is introducing stc excitation model for making the excitation signal . the new algorithm is emulated on the environment of matlab , by comparison with the rebuild voice and the rude voice signal we can draw the conclusion that the speech quality is lowered only a little to 2 . 4kbit / s ’ melp algorithm
在本文最后将给出一种800bit / s的语音编码方案,通过在matlab上仿真,经重建语音信号比较及主观试听表明,该系统性能与美国联邦标准推荐的2 . 4kbps混合激励线性预测( melp )算法较接近或下降有限。 - Basing the american federal 2 . 4kbps melp algorithm , the analysis platform was established for analyzing the and testing the performance of melp codec . this article analyzes the capability of the melp vocoders . finally some advice are given to realize the vocoder in hardware or software
本文以美国联邦标准2 . 4kbps melp算法为基础，在matlab上建立起了分析melp算法的软件平台，对其性能进行了分析并提出了一些改进的建议；另外还针对melp算法的特点对其软硬件实现进行了探讨。 - 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。
