It is my fault writing wrong gamma value, it should be gamma=1. Thank you all.
Now I am checking the lpc and lsp in the syn stage, I guess there is something wrong here, If I found the bug, I will tell you!

I think (gamma=0, alpha=0) gives cep, other than lsp.
BTW, the silent problem was discussed in this thread:
There is no solution yet, but it might help shooting.

I checked the parameter before training,the parameters after mgcep converting(sp to lpc), I guess it maybe the lpc, it is very small, especially the first in every frame, like 0.000100683, but lpc got from the common demo(not using straight sp coverting) is not so small, it is 2.26152 corresponding to the above data. > >Is it normal that lpc is so small using straight demo？
