圆卷积与线卷积在FIR中的实现，通过程序还开深刻理解两者间的差别和各自优劣。 1.圆卷积用在被截出的某段数据中，此时，长度应该定为和输入数据长度一致（一般输入数据大于hn的数），这时圆卷积结果相当于某段被截断出来的数据以非截断的方式经过滤波而得出的结果；线卷积用在各自独立的，离散的数据中，若截断数据也用线性卷积来计算，那么就相当与这部分数据是与源数据是独立的， 得出的结果时域两端会变长，但频谱基本上一样的。差别可以想象。 2.注意圆卷积最开始的输入数据的次序，构造矩阵时要注意。(Circular convolution with the line convolution in the FIR implementation, the program also opened a deep understanding of the difference between the two and their respective pros and cons. A circular convolution with cut out a certain period of data At this point, the length should be set for the same length as the input data (typically input data greater than hn the number), when the circular convolution is equivalent to a certain the results of the truncated data to the non-truncated filtered line convolution with a separate, discrete data, truncated data with a linear convolution calculation, then the equivalent of this part of the data is independent of the source data, the results of both ends of the time domain becomes long, but the spectrum is basically the same. The difference can imagine. Note that the order of the circular convolution of the input data to construct matrix.)

近几年来，在自然语言处理、信号处理、随机过程处理等方法的推动下，语音分析与合成技术获得了很大的发展，突破了传统的单纯语音计算算法的研究。情感语音分析与合成的研究，适应了语音技术的未来发展趋势,由于它能够很好的将语音的口语分析、情感分析与计算机技术有机的融合，为实现以人为本，具有个性化特征的语音合成系统，奠定基础。(STRAIGHT[1] is a high-quality speech analysis, modification and synthesis system based on a simple channel VOCODER concept (in other words a source filter model).)

G729编码和解码的Matlab源程序 调用方法： 1.需要编码时，在 Matlab命令行下输入"G729code(speech)"(请务必保证 speech是已经存在在 Matlab工作区的一个行向量，其中是语音数据)，然后你会在你的文件夹下看到一个"coding.bit"的文件。 2.需要解码时，把"coding.bit"的文件复制到"G729 decoder"的目录下，在Matlab命令行下输入"G729decodermain"，然后你会在文件夹下看到"syn_speech.wav"，那就是重构语音。 enjoy it!
