Dear all.
I’m trying to build HTS with my custom voice using HTS-2.2 demo script.
I have a question about acceleration coefficients.
According to HTS book equation (5.16),
The delta coefficients in time t-1, t, t+1 are computed as below.
Just then, the acceleration coefficients are computed as below.
However, according to /data/script/windows.pl and /data/win/*.win3 included in HTS-2.2 demo,
the acceleration coefficients are computed as below.
So, If it’s correct that I’m thinking,
/data/win/*.win3 file changed as below.
Current : 3 1.0 -2.0 1.0
New : 5 0.25 0.0 -0.5 0.0 0.25
I just wonder whether or not what I think is correct.
Please comment on my calculation mentioned above.
