Td-psolaPitchDuration
使用TD-PSOLA(td-psola、psola)算法,做了一个语音合成,实现语音声调的变调,时长的变化等功能。参考praat源码,提取出其合成方法,效果不错。需要提供pitchtier、durationtier、pointprocess等准换信息文本(可由praat产生)供readfile函数读入(Use TD-PSOLA (TD-PSOLA, PSOLA algorithm, made a speech synthesis, speech tone tone sandhi, long-term changes in the function. Reference Praat source code, extract its synthetic method, the effect of the same.)
