摘　　要：文中分析了语音的正弦谐波模型,给出基于正弦谐波模型的男、女声变换的算法流程,利用高斯建模的方法实现了男、女声特征的互换,利用立方相位内插解决了合成语音时的相位不连续问题。文中利用M AT-LAB进行了仿真实验,验证了算法的有效性,对变换和反变换后的语音质量进行了ABX测试,并给出了此技术的应用前景。The harmonic sinusoidal model of speech was analyzed, and the male-female voice transformation algorithm was given. The male and female characteristics were transformed with gauss model, and the problem of discontinuousness of phase in the process of synthesis was solved by the cubic phase interpolation method. The proposed algorithm was validated by the experiment based on the MATLAB. The ABX test was taken of the result of the experiment, and future applieation of this teehnology was predited.
