STRAIGHT
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).)

附录MATLAB 图像处理命令 1．applylut 功能：在二进制图像中利用lookup 表进行边沿操作。语法： A = applylut(BW,lut) 举例 lut = makelut( sum(x(:)) == 4 ,2) BW1 = imread( text.tif ) BW2 = applylut(BW1,lut) imshow(BW1) figure, imshow(BW2) 相关命令： makelut 2．bestblk 功举例(Appendix MATLAB image processing an order. Applylut functions : the binary image using lookup tables for 2500 operations. Grammar : A = applylut (BW, lut) For lut makelut = (sum (x (:)) == 4. 2) = imread BW1 (text.tif) BW2 = applylut (BW1. lut) imshow (BW1) figure, imshow (BW2) related orders : makelut 2. For bestblk Gong)
