对语音编码的两大类即波形编码和参量编码的优缺点进行了分析,重点对码激励线性预测进行了研究.首先提出了感觉加权滤波器的等效变换方法,然后提出了一种码本部分重叠分割法,计算机模拟实验证明,采用上述方法,可以得到很好的合成音质,并使运算速度显著提高。 The advantages and disadvantages of two main categories of speech coding, namely waveform coding and parametric coding, are analyzed, and emphasis is put on the linear prediction of code excitation.First, an equivalent transform method of perceptual weighting filter is proposed, and then a codebook Partially overlapping segmentation method, computer simulation experiments show that using the above method, you can get a good synthetic sound quality, and the computing speed significantly improved.
