[hts-users:02179] Re: problem with volume after adaptation

[Tóth Bálint <toth.b@xxxxxxxxxxx>]

Dear Junichi Yamagishi,

Thank you very much for your answer.

I’ve checked and HTS calculates GV models from all speakers (including 
average voice speakers and target speaker). When GV is calculated from 
all speakers there are much more overshoots, but in case of calculating 
GV only from the target speaker the synthesized voice (SAT+adaptation) 
still overshoots often.

I normalized all the audio data in the same way.

In case of SI+adaptation (with the same training and adaptation data) 
the overshoots are quite rarely in the synthesized speech, but there are 
still some.

Any help is highly appreciated.

Best Regards,
Balint Toth
