[hts-users:02836] Re: Problem of using lspdf to synthesize

[那兴宇 <nxy-yzqs@xxxxxxx>]

You misloaded the lspsyn voice.

Does it happen at the voice frames or the silence frames? Did you turn on GV option when synthesizing?

Yes, I already tried the 'lspcheck', and there's no problem with the 'lsp.data'.

Besides, I also tried to use the 'lsp2lpc' to transfer 'lsp.data' back to 'lpc.data', and use 'poledf' to resynthesize, and there's no problem with the resynthesized data.

Hi,

Could you try 'lspcheck -r' in SPTK?
