[hts-users:02590] How exactly do we get LSP?


Hi , all
I am getting more confused these days about LSP.
First, I configure the HTSdemo by "MGCLSP=1, GAMMA=1" to get LSP coefficients. But the synthesis part in the Train.pl did get silence results. So I synthesize them independently after the training was done. The results sound normal but there are always noise at the beginning and ending of the setences.

Then I turn to test LSP in SPTK. As I read the tutorial slides by Prof. Tokuda, it was said that the coefficient we get by setting gamma = -1 is LPC ( wraped with alpha !=0 and linear with alpha ==0). In my understanding, the coefficient I got was actually Wraped-LPC rather then LSP. But in the synthesis part, gamma was used to determine MGC or MGC-LSP. And I didnt find the proper setting of training part to get LSP, both in the slide and the INSTALL documents.

My question is, what exactly do we get by setting GAMMA to 1 and MGCLSP to 1 both? Wraped-LPC or LSP?
