Generating confusion matrix with HResults HTK Tool for handwriting recognition ICFHR’s example -

i studying how htk tools works handwriting recognition. following icfhr–2010 tutorial run examples "spanish-numbers" corpus , received resulting hmms (files stored in folder hmm , listed in hmmslist), , res32.mlf results of recognition received hvite. have master label file samplesref.mlf. , want see recognition results statistics, i.e. studying hresults tool.

when run hresults as

 hresults -i samplesref.mlf hmmslist res32.mlf 

i see

====================== htk results analysis =======================   date: tue mar 31 15:21:11 2015   ref : samplesref.mlf   rec : res32.mlf ------------------------ overall results --------------------------  sent: %correct=0.00 [h=0, s=2, n=2]  word: %corr=77.78, acc=77.78 [h=7, d=0, s=2, i=0, n=9] =================================================================== 

but if add option -p in order have confusion matrix see following error message:

~/icfhr$ hresults -p -i samplesref.mlf hmmslist res32.mlf  error [+3331]  index: label millones not in list[0 of 19] fatal error - terminating program hresults 

i understand message means there no hmm name "millones" , found in res32.mlf samples looks like:

"’*’/210341.rec" mil seiscientos cincuenta y siete millones . 

if change res32.mlf text editor res33.mlf content like:

"’*’/210341.rec" m l s e s c 

... , on.

and use samples.mlf (instead of samplesref.mlf) inside looks like:

"*/210341.lab" m l @ q u n e n t o s @ c 

... , on.

i have desired result:

so, main question is:

what simplest way (without text editor) make mlf-files adapted making confusion matrix?

(i suppose miss option of htk tool… tool , option?)

any useful ideas highly appreciated.

in order use -p option, need provide labels list of classes not hmms, (i.e. if you're trying recognize words yes, no, never) "hmmslist" file should written as:

yes no never 

regardless of hmms constitutes words. "hmmslist" file should "labelslist"
