I am trying to do some experiments with intepolation. I used the -i option in hts_engine, but with the parameters -i 2 10 90 I was able only to change the interpolation of the duration between two set of models. As can bee seen in the output trace file:
[Global parameter]
Sampring frequency -> 48000(Hz)
Frame period -> 240(point)
5.00000(msec)
All-pass constant -> 0.55000
Gamma -> 0.00000
Postfiltering coefficient -> 0.00000
Audio buffer size -> 0(sample)
[Duration parameter]
Number of states -> 5
Interpolation size -> 2
Interpolation weight[ 0] -> 10(%)
Interpolation weight[ 1] -> 90(%)
[Stream parameter]
Stream[ 0] vector length -> 35
Dynamic window size -> 3
Interpolation size -> 2
Interpolation weight[ 0] -> 50(%)
Interpolation weight[ 1] -> 50(%)
MSD flag -> FALSE
GV flag -> TRUE
GV weight -> 100(%)
GV interpolation size -> 2
GV interpolation weight[ 0] -> 50(%)
GV interpolation weight[ 1] -> 50(%)
Stream[ 1] vector length -> 1
Dynamic window size -> 3
Interpolation size -> 2
Interpolation weight[ 0] -> 50(%)
Interpolation weight[ 1] -> 50(%)
MSD flag -> TRUE
MSD threshold -> 0.50000
GV flag -> TRUE
GV weight -> 100(%)
GV interpolation size -> 2
GV interpolation weight[ 0] -> 50(%)
GV interpolation weight[ 1] -> 50(%)
Stream[ 2] vector length -> 31
Dynamic window size -> 1
Interpolation size -> 2
Interpolation weight[ 0] -> 50(%)
Interpolation weight[ 1] -> 50(%)
MSD flag -> FALSE
GV flag -> FALSE
Is it possible to change also the interpolation ratios in streams?I mean Interpolation weight[ 0] and Interpolation weight[ 1]. And how is it possible?
Thank you a lot.
