[hts-users:02198] TRANSP of monophone reestimation

[燕鹏举 <yanpengju@xxxxxxxx>]

Hi there,

I'm studying the standard HTS demo process (Training.pl), I found that the
TRANSP during monophone re-estimation isn't updated appropriately.

Before the step of $ERST0, the transition matrices contain non-0
probabilities to current and the immediate next states, say

<TRANSP> 7
 0.000000e+00 1.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 4.952075e-01 5.047925e-01 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 7.473042e-01 2.526958e-01 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 7.416168e-01 2.583832e-01
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 9.256996e-01
7.430040e-02 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
5.919777e-01 4.080223e-01
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00

But after $ERST0 (HERest on monophones), the transition probability to the
current state is 0, say

<TRANSP> 7
 0.000000e+00 1.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 1.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 1.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 1.000000e+00
0.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
1.000000e+00 0.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 1.000000e+00
 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00 0.000000e+00
0.000000e+00 0.000000e+00

You can check the file monophone.mmf.embedded.gz in your own cmp folder.

Can anybody give any hint? Thanks.
