[hts-users:02996] Re: Silent waveforms in synthesis with hts_engine


Hi,
     I guess the versions of your HMGenS and HERest, HHEd are  incompatible.
     I suggest you check the version of your used tools.

Hi

my problem is that synthesis with hts_engine worked for all other voices that were trained the same way, even for a small subset of the voice that doesn't work!

Synthesis with HMGenS returns several HMM Def errors such as

HMM Def Error: Variance Vector expected at line 12/col 14/char 672 in models/1//nosil-gv.mmf

and

cannot open file testfile_30490.apf
cannot open file testfile_30490.f0
cannot open file testfile_30490.mcep

straight:  can't read spectrum file

Since my synthesised wavefiles from hts_engine have no feature values, I guess that tuning the amplitude wouldn't help!

Hi,
    i added the ap stream to "hts_engine API", and it's run ok. And  yours silent waveforms are not really silent when you tune the scale of the amplitute ,you can see the waveform exist. So as to Oura, the main difference between mel-cepstrum from SPTK and STRAIGHT is the scale, because of the Matalb process of waveform. So you can add the anergy to the mcep yourself when processing.
   hope my answer can help you.
