[hts-users:01489] Re: hts_engine-0.99 does not generate normal speech in HTS-demo using 12-th order LSP


Hi,

In the failing HTS_calloc call the values of num and size are actually
num=1060370154 (GASP!, that's why calloc fails) and size=4.

I see that you have changed the GV pdf loading mechanism
between hts_engine_API-0.95 and -0.96/0.99, and besides I was
trying to use models trained with HTS-2.1beta into hts_engine-0.96/0.99.

Did you change the GV pdf format between HTS-2.1beta and HTS-2.1RC1?

Yes, we changed the header of GV pdf in hts_engine API 0.96.
In 0.95, its format is
dimensionality (4-byte integer)
mean (float)
...
variance (float)
...

In 0.96, its format is
dimensionality (4-byte integer)
number of pdfs (4-byte integer)
mean (float)
...
variance (float)
...

Similar discussions have been made in hts-users:01300, 1302, 1303, and 1304.

If yes, does that mean that although the hts_engine_API and HTS
are distributed as separate packages and with different version
numbering schemes, there is still a strong mutual dependency
between precise versions of both packages?

GV pdfs are generated by HTS-demo/data/Makefile, not HTS itself.
So I think hts_engine API and HTS are independent.

Sometimes we have to change model format etc.
I recommend you to re-train your model using the latest HTS and demo script
because the latest one may have less bugs.

# I personally believe that the latest HTS is always the best one :-)
