    读取语音信号(用matlab的wavread指令),把语音信号分帧、加窗,进行清浊分割,提取基 频,这一部分较简单,自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数,可调用lpcfit.m 程序(我提供,见附件),将源、目标语音的浊音 段的lpc系数进行DTW规整,调用pathita2.m 程序(我提供,见附件)。将规整得到的lpc系数 转换成lsp参数,调用lpcar2ls.m 程序(我提供,见附件), 再进行转换映射,调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)
