Thank you for your answer, but I have some further questions about the details of the lf0 and mgc parameter extraction.
1. Why added 5ms/25ms waveform to head/tail? why not other length, like 10ms head or the 5ms tail? I guess it must have some special reason, I read the getf0.tcl. the default minpitch/maxpitch for speech is 60/400Hz, so if the autocorrelation method is generally used to caculate the first frame pitch, it should be added (1/60)s=16.7ms waveform for the head at least, but now the number is 5ms/25ms, so can you explain more detail? 2. I checked the *.mgc file, it always have less two frames than the *.raw file, so my question is the discarded two frames is the raw file head two frame or the raw file tail frame ? >
