[hts-users:02664] Re: hts_engine and HMGenS output diffrences

[ali azimizadeh <ali.azimizadeh@xxxxxxxxx>]

No, the unseen-model isn't my problem. the main problem is output quality. look, i get a same input (unseen data) to the hts_engine and HMGenS. the output parameters are lf0, bap, mgc files. i use these files to synthesize the waveform by STRAIGHT method.
finally, i have two different .wav files that both of the are correct. but, the hts_engine output quality is less than HMGenS one. the mmf output frame size is 560 but the hts_engine one is 469. the hts_engine output has distortion. but note that i didn't use hts_engine perfectly, just have used until HTS_Engine_create_pstream(&engine); 

I think the differences are little but they are effective on waveform. if you have any suggestion please send me.

Hi,

For mmf model, there might be an unseen-model problem which could be solved by the decision tree structure in hts_engine.
Is your test utt from inside or outside the training data or a pre-defined gen data?

Hi,

I have a model in both hts_engine and mmf versions that trained by HTS2.1.1beta Adapt.  i tested models by the same utterance and compared their outputs (sp, lf0 and bap). unfortunately, the frame size are not the same in outputs.

Is this difference normal? Does the initial parameters (like frame rate,...) effect on this difference?

 

finally, can i expect the same results from hts_engine models and mmf ones?
