[hts-users:02259] Re: Error in train transitions matrix

I made a stupid typo mistake... It's OK now. Thanks. :)

Hi Keiichiro,

Thanks for your reply. However, the same error still occurs when I use command below,

/usr/local/HTS-2.1/bin/HERest -A -B -C xxx/configs/trn.cnf -D -T 1 -S xxx/data/scp/train.scp -I xxx/data/labels/full.mlf -m 1 -u t -w 3 -t 1500 100 5000 -H xxx/models/qst001/ver1/cmp/untied.mmf -M xxx/models/qst001/ver1/cmp -C xxx/configs/nvf.cnf -s xxx/stats/qst001/ver1/cmp.stats.untied -w 0.0 xxx/data/lists/full.list

Remove the -t command doesn't help either. Is there any other thing I have to do to turn off the HSMM BW training process or should I use a old version of HTS?

Many thanks.

Technically, state alignment using HSMM is not implemented.
Your .hed file converted HSMMs to HMMs.
Therefore, '-R dur.mmf', '-N durdir', and 'durlist' are not required for HERest.

Hi all,

I want use the HSMM I've trained to do state alignment, thus I use Simon's recommendation to deal with this issue. I do this as follows.

1.Untie the shared transition stuctrue and retie it in terms of each phone, my .hed file is:
TR 2
UT {*.transP}
TI T_a {(*-a+*).transP}
TI T_ai {(*-ai+*).transP}
TI T_an {(*-an+*).transP}
TI T_ang {(*-ang+*).transP}
TI T_ao {(*-ao+*).transP}
AT 2 2 0.9 {*.transP}
AT 2 3 0.1 {*.transP}
AT 3 3 0.9 {*.transP}
AT 3 4 0.1 {*.transP}
AT 4 4 0.9 {*.transP}
AT 4 5 0.1 {*.transP}
AT 5 5 0.9 {*.transP}
AT 5 6 0.1 {*.transP}
AT 6 6 0.9 {*.transP}
AT 6 7 0.1 {*.transP}

There is no problem at this stage. The model file is stored in untiedt.mmf
2. Retrain the transition matrix using the commond below.

/usr/local/HTS-2.1/bin/HERest -A -B -C xxx/configs/trn.cnf -D -T 1 -S xxx/data/scp/train.scp -I xxx/data/labels/full.mlf -m 1 -u t -w 3 -t 1500 100 5000 -H xxx/models/qst001/ver1/cmp/untiedt.mmf -N xxx/models/qst001/ver1/dur/untied.mmf -M xxx/models/qst001/ver1/cmp -R xxx/models/qst001/ver1/dur -C xxx/configs/nvf.cnf -s xxx/stats/qst001/ver1/cmp.stats.untiedt -w 0.0 xxx/data/lists/full.list xxx/data/lists/full.list
However, it shows that  Processing Data: xxx_0001.cmp; Label xxx_0001.lab

What's wrong with my manipulation? (Machine: 64bit Linux, 16GB mem)

Thanks for help!
