Hi Ken and All,

Thanks for all the helpful hints in the forums. I could solve quite some errors but it seems I don't know what to do about this one.
[By now I've been trice through the process of building a single-word (10 only) speech recogniser with HTK using the HTK Book and the Voxforge Tutorial. The first time my recognition results were 100% but even when running the recogniser offline it only recognised two of these ten words even when different waves were loaded that did not contain these two words. Anyhow, I felt there was something wrong so I started over again and again.]

This time, in step 7 of the Voxforge Tutorial, when executing the following:
laptop:~$ HERest -C config -I phones0.mlf -t 250.0 150.0 1000.0 -S train.scp -H hmm5/macros -H hmm5/hmmdefs -M hmm6 monophones1

I get this warning:
Pruning-On[250.0 150.0 1000.0]
 WARNING [-2331]  UpdateModels: sp[20] copied: only 0 egs in HERest

I'm not sure how serious it is and whether I should ignore or solve it. Does anyone know what the solution might be?
I have a single-word grammar with ten words. These ten words are trained with 345 wav-files containing one word each. It seems quite problematic if "0 egs" out of 345 wav-files can be processed.

I converted my files from 44100Hz to 16000Hz, because I read that for the SOURCERATE to be 625.0 16KHz is the right sampling rate. Now earlier, when executing HCopy -T 1 -C config -S codetr.scp to create the *.mfc's I used the configuration parameter TARGETKIND = MFCC_0_D_A, although the HTK Tutorial suggests to use TARGETKIND = MFCC_0 in step 5 of the HTK Tutorial. However, when using TARGETKIND = MFCC_0 and one step further executing:
HERest -C config -I phones0.mlf -t 250.0 150.0 1000.0 -S train.scp -H hmm0/macros -H hmm0/hmmdefs -M hmm1 monophones0
almost all of my wav-files got the following error:
WARNING [-7324]  StepBack: File /*.mfc - bad data or over pruning in HERest
So in general, there is something wrong with my wav-files. Are they too short (min = 0.43sec, max = 1.66sec, usually 0.8sec)?

I'd appreciate any help I can get! Cheers.

Katie

See my post in this thread: Create hmm11 - usually this means that you don't have enough speech for a particular phone, and can be ignored... However, this is the 'sp' phone.  I think your problem is related to this statement: "These ten words are trained with 345 wav-files containing one word each."

The "sp" phone is the short-pause interword phone... if all you have are single word recordings, then you will not have any short-pauses.  See Step 7 - Fixing the Silence Models for a short description of how the short-pause model is created.  You might try recording a few sentences (multiple words) and see if this helps.

>Are they too short (min = 0.43sec, max = 1.66sec, usually 0.8sec)?

I really don't know - have you tried with longer wav files?  Do you get the same error?  You say "almost all of my wav-files got the following error:" - are the ones that do not get an error longer wav files?

>pruning in HERest

look up the "-t" parameter (from -t 250.0 150.0 1000.0) in HTK book, I think these can be adjusted so that you get higher training thresholds...
