Step 10 - Making Tied-State Triphones

You will be using the global.ded script you created in a previous step, confirm that its contents are as follows:

AS sp
RS cmu
MP sil sil sp

Then execute the HDMan command against the entire lexicon file, not just the training dictionnary we have used thus far (that is why we needed to create a phonetically balanced grammar in Step 2):

$HDMan -A -D -T 1 -b sp -n fulllist -g global.ded -l flog dict-tri ../lexicon/voxforge_lexicon

this creates 2 files:

Next create a new fulllist1 file and copy the contents of the fulllist and triphones1 into it. Copy the fixfullist.pl script to your 'voxforge/manual folder', and execute as follows to remove any duplicate entries:

$perl fixfulllist.pl fulllist1 fulllist

Your updated file should look like this: fulllist

tree.hed script

Next you create a new script called tree.hed in your 'voxforge/manual' folder containing the following:

RO 100 stats

TR 0

TR 2

(Note: make sure you have a blank line at the end of this file)

Here is a short description of the commands contained in tree.hed:

RO - outlier threshhold
1st "TR" - trace level
QS - question - defined by the user (see quests.hed file in HTK distribution - RM demo folder)

(each QS command loads a single question and that question is defined by a set of contexts)

2nd "TR" - enables intermediate level progress reporting
TB - clusters one specific setof states - created with the mkclscript.prl command
AU - new list of triphones expanded to include all those neede for recognition
CO - used to compact the model set, creates new list of models
ST - synthesize previously unseen triphones

Refer to the HTK book for details on these commands.

Next run the mkclscript.prl (you should have already copied it from your HTK folder in 'htk-3.3/samples/RMHTK/perl_scripts' folder to your voxforge/HTK_scripts folder) script as follows:

$perl ../HTK_scripts/mkclscript.prl TB 350 monophones0 >> tree.hed

Then add the following to the end of your tree.hed file:

TR 1

AU "fulllist"
CO "tiedlist"

ST "trees"

Your file should look like this: tree.hed

Next create 3 more folders: hmm13-15

Then execute the HHEd command:

$HHEd -A -D -T 1 -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1

This command creates 3 files:

Next run HERest 2 more times:

$HERest -A -D -T 1 -T 1 -C config -I wintri.mlf -s stats -t 250.0 150.0 3000.0 -S train.scp -H hmm13/macros -H hmm13/hmmdefs -M hmm14 tiedlist

This command creates 2 files:

$HERest -A -D -T 1 -T 1 -C config -I wintri.mlf -s stats -t 250.0 150.0 3000.0 -S train.scp -H hmm14/macros -H hmm14/hmmdefs -M hmm15 tiedlist

This creates 2 files:

The hmmdefs file in the hmm15 folder, along with the tiedlist file, can now be used with Julian to recognize your speech!

about tree.hed

By amza - 4/9/2008 - 1 Replies

Hi,

I am doing a research on Indonesian speech recognition now. I am curious about tree.hed script. Can I get the explanation about tree.hed content, so that I can modify it according to my own language. You can send the explanation to my email (amel_dara@yahoo.com) if it is too long to post here. Thank you so much.

regards,

amza

missing state 2 for b

By kmaclean - 2/26/2008

Lucian said (from this thread):

I realized that this "missing state 2 for b" problem is due to the double chop in HTK_Scripts/mkclscript.prl script, as instructed by the tutorial instructions.
After I change it back to a single "chop;" command, everything works.

This might occur if you are running the "HTK_Scripts/mkclscript.pl" script in Cygwin/Windows.

Hi,

Recently i've run this command:

It gave me this error:

ERROR IN STEP 10

By rovira74 - 1/21/2008 - 4 Replies

Hi,

I am almost through with this tutorial but step 10 gives me this error.

HHEd
465/465 Models Loaded [5 states max, 1 mixes max]
RO 100.00 ''
Setting outlier threshold for clustering
RO->LS stats
and loading state occupation stats
ERROR [+7251] LoadStatsFile: unknown name b at line 1
FATAL ERROR - Terminating program C:\cygwin\HTK\htk-3.3-windows-binary\htk\HHEd

I can't figure out what the problem It complains of the 'stats' file generated in the previous step but the content of this file is the same as ones successfully cpmpleted.

Any help will be appreciated.

thanks.

Please help me with this error

Hi,

My dictionary have only ten digits (oh, zero, one..., nine) from TIDIGITS database, I don't know if I can use the fulllist in your web site. I tried to use it and I received this error when I run this command in HTK book:

HHEd -B -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1 > log

ERROR [+2662] FindProtoModel: no proto for y-uh+r in hSet

I don't know where is this error comes from and how to fix it, can you help me?

Thanks a lot

Question item

By Manuel - 9/25/2007 - 1 Replies

Hi, when I start

HHEd -A -D -T 1 -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1

It give me following warning

WARNING [-2631] QuestionCommand: No items for question R_Silence
in HHEd
WARNING [-2631] QuestionCommand: No items for question R_dd
in HHEd
WARNING [-2631] QuestionCommand: No items for question R_el
in HHEd
WARNING [-2631] QuestionCommand: No items for question R_end

First i believed that I had to add word for this question, but there are question that use phoneme that not exist, why?

For example

QS "R_dd" { *+dd }

Tks

Possible error in tutorial?

By Manuel - 9/7/2007 - 1 Replies

In the last step there's the following instruction:

Then execute the HDMan command against the entire lexicon file, not just the training dictionnary we have used thus far (that is why we needed to create a phonetically balanced grammar in Step 2):

$HDMan -A -D -T 1 -b sp -n fulllist -g global.ded -l flog dict-tri ../lexicon/voxforge_lexicon

But this introduce some phonemes that are only in the voxforge_lexicon, not in our dict, so there are no audio file for that.

This situation is the cause of an error when do:

$HHEd -A -D -T 1 -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1

ERROR [+2662] FindProtoModel: no proto for p in hSet

"p" is only an example of phonemes without audio registration.

I've try to use dict instead of ../lexicon/voxforge_lexicon, and it work correctly.

I'm wrong?

Thanks

Manuel

Last 2 HERest

By Manuel - 9/7/2007 - 2 Replies

I need only the last instruction to create my acoustic model, but whend I do

HERest -A -D -T 1 -T 1 -C config -I wintri.mlf -s stats -t 250.0 150.0 3000.0 -S train.scp -H hmm13/macros -H hmm13/hmmdefs -M hmm14 tiedlist

it give me the following error:

ERROR [+5010] InitSource: Cannot open source file t+aa
ERROR [+7010] LoadHMMSet: Can't find file
ERROR [+2321] Initialise: LoadHMMSet failed
FATAL ERROR - Terminating program HERest

I understand that it try to open t+aa as file, but it isn't a file, it the first line of tiedlist file. It's wrong how I use HERest and its parameter?

Can you help me?

P.s. I promise that it's the last time that I ask help to you ... I hope. :D
