[hts-users:02832] Re: Problem of using lspdf to synthesize


There was no frequency warping factor problem when I encountered this lspdf trouble.

I got the LSP coefficients from the LPC coefficients:

-------------
lpc -l 512 -m 24 windowed.data > lpc.data

lpc2lsp -m 24 -n 256 lpc.data > lsp.data

poledf -m 24 -p 80 lpc.data excite.data > lpcsyn.data

lspdf -m 24 -p 80 lsp.data excite.data > lspsyn.data
-------------

It turns out that the lpcsyn.data is ok, while the lspsyn.data has the problem I mentioned -- some synthesized points' value turn out to be extremely large.

However, the problem disappers when m<20.

I attached the three wave files with the order m=24: original.wav, lpcsyn_m24.wav, lspsyn_m24.wav.

Please help me to solve the problem.

When using lspdf, the frequency warping factor should be zero.

Hello!

I encountered a problem when using lspdf for synthesis:

When the lsp order is relatively large, e.g. m>20, some synthesized points' value turn out to be extremely large, which makes the synthesized speech sound annoying. And larger the lsp order, more the abnormal synthesized points.
