Hi,
I am having problems using HERest for supervised adaptation on a 'SHARED' System (I assume this means a [tied-state] triphone based system). I am using HTK 3.3 on Linux (FC4).
I have followed a similar approach to the Adaptation steps outlined in the following 2 email posts to HTK-Users, which talked about HERest supervised adaptation using HTK 3.3, but on a 'PLAIN' system (which I assume means monophones):
- http://htk.eng.cam.ac.uk/pipermail/htk-users/2006-July/005308.html - http://htk.eng.cam.ac.uk/pipermail/htk-users/2006-July/005310.html
I am trying to adapt an Acoustic Model I created using the steps outline in the tutorial in the HTK 3.2 Book using HTK 3.3 and HERest. I don't think there is a problem with my data because I successfully adapted the same Acoustic Model (created using HTK3.3) using HTK 3.2 and HEAdapt.
The approach I took was as follows:
Steps #1-11: Created Acoustic Models
Created Tied-State Triphones as per the tutorial in the HTK 3.2 Book
Step #12: Preparation of the Adaptation Data
(1) adaptWords.scp contains the list of adaptation files (2) adapt.mlf contains the conrresponding transcription for adaptation files
(3) config contains the basic configuration variables for MFCC feature extraction:
TARGETKIND = MFCC_0_D_N_Z TARGETRATE = 100000.0 SAVECOMPRESSED = T SAVEWITHCRC = T WINDOWSIZE = 250000.0 USEHAMMING = T PREEMCOEF = 0.97 NUMCHANS = 26 CEPLIFTER = 22 NUMCEPS = 12
(4) Realign the training data:
HVite -A -D -V -T 1 -l '*' -o SWT -b SENT-END -C config -H hmm15/macros -H hmm15/hmmdefs -i adaptPhones.mlf -m -t 250.0 150.0 1000.0 -y lab -a -I adaptWords.mlf -S adapt.scp dict tiedlist
This creates adaptPhones.mlf
Step #13: Generating the Transforms
(1) regtree.hed as following:
RN "models" LS "stats" RC 32 "rtree"
(2) Generate Regression Class Tree:
HHEd -A -D -V -T 1 -H hmm15/macros -H hmm15/hmmdefs -M hmmAdapt regtree.hed tiedlist
This creates 4 files in hmmAdapt:
- hmmdefs
- macros
- rtree.tree
- rtree.base
Step #14: Global MLLR
(1) create a "glob" (under hmmAdapt folder) file as follows:
~b "glob"
<MMFIDMASK> *
<PARAMETERS> MIXBASE
<NUMCLASSES> 1
<CLASS> 1 {*.state[2-4].mix[1]}
(2) config_adapt_global contains the configuration variables for global transformation:
HADAPT:TRANSKIND = MLLRMEAN HADAPT:USEBIAS = TRUE HADAPT:BASECLASS = glob HADAPT:ADAPTKIND = BASE HADAPT:TRACE = 61 HMODEL:TRACE = 512
(7) tiedlist contains the list of HMMs
(8) Perform 1st pass Global Adaptation using HERest as following:
HERest -A -D -V -T 1 -C config -C config_adapt_global -S adapt.scp -I adaptPhones.mlf -H hmmAdapt/macros -H hmmAdapt/hmmdefs -H hmmAdapt/glob -K hmmAdapt mllr -u a tiedlist
This creates a file called 'mfc.mllr' in hmmAdapt
Step #15: Adaptation using Regression Class Tree
(1) config_adapt_regc contains the configuration variable for regression class tree transform:
HADAPT:TRANSKIND = MLLRMEAN HADAPT:USEBIAS = TRUE HADAPT:BASECLASS = rtree.tree HADAPT:ADAPTKIND = TREE HADAPT:SPLITTHRESH = 1000.0 HADAPT:TRACE = 61 HMODEL:TRACE = 512
(1) Perform 2nd pass global transformation:
HERest -a -A -D -V -T 1 -C config -C config_adapt_regc -S adapt.scp -J hmmAdapt mllr -I adaptPhones.mlf -H hmmAdapt/macros -H hmmAdapt/hmmdefs -H hmmAdapt/mfc.mllr -K hmmAdapt mllr1 -u a -z regc.tmf tiedlist
When I run this I get the a segmentation fault as follows:
HERest -a -A -D -V -T 1 -C config -C config_adapt_regc -S adapt.scp -J hmmAdapt mllr -I adaptPhones.mlf -H hmmAdapt/macros -H hmmAdapt/hmmdefs -H hmmAdapt/mfc.mllr -K hmmAdapt mllr1 -u a -z regc.tmf tiedlist HTK Configuration Parameters[17] Module/Tool Parameter Value # HMODEL TRACE 512 # HADAPT TRACE 61 # HADAPT SPLITTHRESH 1000.000000 # HADAPT ADAPTKIND TREE # HADAPT BASECLASS rtree.tree # HADAPT USEBIAS TRUE # HADAPT TRANSKIND MLLRMEAN # NUMCEPS 12 # CEPLIFTER 22 # NUMCHANS 26 # PREEMCOEF 0.970000 # USEHAMMING TRUE # WINDOWSIZE 250000.000000 # SAVEWITHCRC TRUE # SAVECOMPRESSED TRUE # TARGETRATE 100000.000000 # TARGETKIND MFCC_0_D_N_Z HTK Version Information Module Version Who Date : CVS Info HERest 3.3 CUED 28/04/05 : $Id: HERest.c,v 1.3 2005/07/22 10:17:13 mjfg Exp $ HShell 3.3 CUED 28/04/05 : $Id: HShell.c,v 1.2 2005/05/12 15:51:24 jal58 Exp $ HMem 3.3 CUED 28/04/05 : $Id: HMem.c,v 1.1.1.1 2005/05/12 10:52:50 jal58 Exp $ HMath 3.3 CUED 28/04/05 : $Id: HMath.c,v 1.1.1.1 2005/05/12 10:52:50 jal58 Exp $ HSigP 3.3 CUED 28/04/05 : $Id: HSigP.c,v 1.1.1.1 2005/05/12 10:52:51 jal58 Exp $ HAudio 3.3 CUED 28/04/05 : $Id: HAudio.c,v 1.2 2005/05/12 15:51:23 jal58 Exp $ HWave 3.3 CUED 28/04/05 : $Id: HWave.c,v 1.1.1.1 2005/05/12 10:52:52 jal58 Exp $ HVQ 3.3 CUED 28/04/05 : $Id: HVQ.c,v 1.1.1.1 2005/05/12 10:52:52 jal58 Exp $ HLabel 3.3 CUED 28/04/05 : $Id: HLabel.c,v 1.2 2005/05/12 15:51:24 jal58 Exp $ HModel 3.3 CUED 28/04/05 : $Id: HModel.c,v 1.4 2005/07/22 10:17:01 mjfg Exp $ HParm 3.3 CUED 28/04/05 : $Id: HParm.c,v 1.2 2005/07/22 10:17:02 mjfg Exp $ HTrain 3.3 CUED 28/04/05 : $Id: HTrain.c,v 1.1.1.1 2005/05/12 10:52:51 jal58 Exp $ HUtil 3.3 CUED 28/04/05 : $Id: HUtil.c,v 1.2 2005/07/22 10:17:02 mjfg Exp $ HFB 3.3 CUED 28/04/05 : $Id: HFB.c,v 1.3 2005/05/12 15:51:24 jal58 Exp $ HAdapt 3.3 CUED 28/04/05 : $Id: HAdapt.c,v 1.3 2005/07/22 10:17:01 mjfg Exp $ HMap 3.3 CUED 28/04/05 : $Id: HMap.c,v 1.1.1.1 2005/05/12 10:52:53 jal58 Exp $ Using baseclass macro "glob" from file hmmAdapt/glob HERest ML Updating: XForms System is SHARED 1037 Logical/81 Physical Models Loaded, VecSize=25 3 MMF input files Segmentation fault
Any help would be greatly appreciated,

- Milestone changed from 0.1-beta to 0.1-gamma
for 0.1 beta release - created user tutorial that uses HTK version 3.2.1 rather than 3.3 - until issues with HERest adaption get addressed Need a fix for 0.1 gamma release
comment:3 Changed 15 years ago by anonymous
Need to see if this has been fixed in HTK release 3.4 - see message
