This is because Ubuntu's sh command in /bin is mapped to /bin/dash instead of /bin/bash. Doing the following will sort out the issue sudo rm /bin/sh sudo ln -s /bin/bash /bin/sh http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/running-htk_compile_model_sh-on-ubuntu Wed, 02 Jul 2008 16:07:44 -0500 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/how-to-speed-up-step-7-of-the-script from this post: Ken, Here is my update of Step 7 fragment of the script: make_hmm4 () { LINE="start" NUM=1 rm -rf ./interim_files/hmm4/hmmdefs.tmp1 rm -rf ./interim_files/hmm4/hmmdefs.tmp2 while [ `echo ${LINE} | awk '{ print $1 }'` != "" ]; do LINE=`cat -n ./interim_files/hmm4/hmm_sil | grep ^[[:space:]]*${NUM}[[:space:]] | sed s/^[[:space:]]*[[:digit:]]*//g` if [ `echo ${LINE} | awk '{ print $2 }'` = "\"sil\"" ]; then while [ `echo ${LINE} | awk '{ print $1 }'` != "<ENDHMM>" ]; do echo ${LINE} >> ./interim_files/hmm4/hmmdefs.tmp1 echo ${LINE} >> ./interim_files/hmm4/hmmdefs.tmp2 # print_process ${NUM} let "NUM += 1" LINE=`cat -n ./interim_files/hmm4/hmm_sil | grep ^[[:space:]]*${NUM}[[:space:]] | sed s/^[[:space:]]*[[:digit:]]*//g` done echo ${LINE} >> ./interim_files/hmm4/hmmdefs.tmp1 NUM2=1 while [ ${NUM2} != "28" ]; do LINE2=`cat -n ./interim_files/hmm4/hmmdefs.tmp2 | grep ^[[:space:]]*${NUM2}[[:space:]] \ | sed s/^[[:space:]]*[[:digit:]]*//g` case ${NUM2} in 1 ) echo ${LINE2} | sed s/~h\ \"sil\"/~h\ \"sp\"/g >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 2 ) echo ${LINE2} >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 3 ) echo ${LINE2} | sed s/5/3/g >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 10 ) echo ${LINE2} | sed s/3/2/g >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 11 | 12 | 13 | 14 | 15) echo ${LINE2} >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 22 ) echo ${LINE2} | sed s/5/3/g >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 24 ) echo "0.000000e+000 1.000000e+000 0.000000e+000" >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 25 ) echo "0.000000e+000 0.900000e+000 0.100000e+000" >> ./interim_files/hmm4/hmmdefs.tmp1 ;; 26 ) echo "0.000000e+000 0.000000e+000 0.000000e+000" >> ./interim_files/hmm4/hmmdefs.tmp1 ;; esac let "NUM2 += 1" done fi echo ${LINE} >> ./interim_files/hmm4/hmmdefs.tmp1 # print_process ${NUM} let "NUM += 1" done cat ./interim_files/hmm4/hmm_before_sil ./interim_files/hmm4/hmmdefs.tmp1 > ./interim_files/hmm4/hmmdefs rm -rf ./interim_files/hmm4/hmmdefs.tmp1 rm -rf ./interim_files/hmm4/hmmdefs.tmp2 rm -rf ./interim_files/hmm4/hmm_before_sil rm -rf ./interim_files/hmm4/hmm_sil return 0 } extract_sil_model(){ SWITCH=0 BEGIN=0 NUM2=0 for TOKEN in `cat -n ./interim_files/hmm4/hmmdefs ` do if [ "${TOKEN}" = "\"sil\"" ]; then SWITCH=1 fi if [ "${SWITCH}" = "1" ]; then YES=$(echo $TOKEN | grep ^[[:digit:]+]) if [ "1${YES}1" != "11" ]; then #### supposed to be [ $YES != ]; but didn't work ?

Script http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/how-to-speed-up-step-7-of-the-script Thu, 19 Jun 2008 16:02:54 -0500 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/execution-stops-at-step-5 The first time I ran HTK_Compile_Model.sh it stopped at step 5 and complained that it could not find sample1.wav. The message indicated it was looking in a directory one level up, but the Howto calls for the wav files to be stored two levels up in voxforge/train/wav directory. I found that after: mkdir auto/train and mkdir auto/train/wav, copy all sample*.wav files to this new wav directory mkdir auto/train/mfcc then the script ran perfectly to the end. Maybe I missed something, but hope it helps. http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/execution-stops-at-step-5 Wed, 05 Mar 2008 08:16:09 -0600 http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/steep-5-missing Hi, http://www.voxforge.org/home/dev/acousticmodels/linux/create/htkjulius/how-to/script/comments/steep-5-missing Fri, 28 Dec 2007 05:24:33 -0600
