说明：  psola的matlab源码,这里提醒各位，psola的调整算法，有很大的局限性，一方面是准确的标注很难获得，另一方面，psola调整之后，往往会带来比较大的负面作用，包括噪音和机器声，使得合成的质量会有明显下降。
(psola source of Matlab, here to remind you that psola adjustment algorithm, it has great limitations, one is accurate tagging difficult to obtain, on the other hand, psola adjustment, that would cause more negative effects, including noise and machines, making the quality of synthesis will be decreased.)
