[hts-users:00645] Re: F0 contours become flat


Hi,

I've been reading the GV information as explained in your article
Interspeech 2005 and I notice that the MOS improves when GV is used in
mel-cepstral, but perceptual tests don't show an improvement when applied to
F0 (as explained in the paper, perhaps caused by some data errors).

Perhaps measuring the RMSE in the F0 could show if the predicted contour
with GV minimizes the error in comparison with the conventional method.

Greetings

In our internal version we use GV.
It can reduce this problem.
