Hi all, First of all, thanks you very much for allinfo that Voxforge give to the community. I have an error in Julius v4.0 but I don't know what's the matter :

Error: voca_load_wordlist: line 1: phone "silB" not found

Error: voca_load_wordlist: line 1: phone "silE" not found

I'm using julius as an isolated word recognizer. I used to use Julian with this command :

julian -input mic -h all_words_23_hmmsdef.mmf -v all_words_23.dict -dfa all_words_23.dfa -rejectshort 150 -output 4 -progout -1pass -headmargin 50 -tailmargin 50

Now I use the option in Julius 4.0 that allow isolated word recognition :

/julius-4.0 -input mic -h all_words_23_hmmsdef.mmf -w all_words_23.dict -rejectshort 150 [....]

I tried to add silB and silE in my dictionnary, but julius still complains. Does anyone have an idea or could tell a place to find the info? Thks a lot for your help. Bruno.

I suppose that complain means that silB is missing in .mmf file. The solution to this problem is not to add silB in the dictionary but to remove them from a dictionary and from grammar file.

I tried to modify my mmf file by duplicating the HMM for "sil" and I renamed them "silE" and "silB" and I added this two word to the dictionnary : julius now launch without error but the recognition doesn't work at all : i always get something like "no survived word found".... Which means the way it did it doesn't work. Do I misunderstand what you've written?

Hi

I vaguely remember getting this error when I was first starting out with HTK/Julius ... The Julius 3.2 manual (check the 4.0 manual to make sure this still applies) says this:

   Word Dictionary
       -v dictionary_file
              Word dictionary file (required).
 
       -silhead {WORD|WORD[OUTSYM]|#num}
 
       -siltail {WORD|WORD[OUTSYM]|#num}
              Sentence  start  and  end silence word as defined in the dictio-
              nary.  (default: "<s>" / "</s>")
 
              Julius deal these words as  fixed  start-word  and  end-word  of
              recognition.   They  can  be defined in several formats as shown
              below.
 
 
                                       Example
           Word_name                     <s>
           Word_name[output_symbol]   <s>[silB]
           #Word_ID                      #14
 
            (Word_ID is the word position in the dictionary
             file starting from 0) 

Therefore your problem might be related to the default silence start and end words in Julius - maybe change it to"silB" and "SilE".

Please let us know if this fixes it.

thanks,

Ken

The fatc is that my hmm is not phoneme based but word based : I learnt the models on a labelled corpus, each label for each word (close to the yes/no tutorial). As all words where pronounciated one after and other with a pause of 2sec between, there is idea of begin and end silence. So the only one model that I have for silence is a model named "sil". So when I specify the silhead and siltail option, I get :

WARNING: m_chkparam: "-silhead" only for N-gram, ignored WARNING: m_chkparam: "-siltail" only for N-gram, ignored

Next I treid with the -wsil option, like this : -wsil sil sil sp I also added the word

SIL sil

to my dictionnary in the first line (julius was complaining about :

Error: voca_load_wordlist: line 1: phone "silB" not found

Error: voca_load_wordlist: line 1: phone "silE" not found

Error: voca_load_wordlist: the line content was: 0 [ACTIVATION] activation

) Even if I don't have a sp model, Julius now doesn't complain and launch. But the result is that recognition doesn't work, giving me a constant "input processed, but no survived word". I'm a bit confused and now I don't what else to try....

Sorry, I don't know why the forum doesn't want to format my message as I'm trying...

Why do you want to use Julius for isolated words? HVite should be enough. Btw, does it work fine for you?

Can you just share your data files - mmf, dfa and dictionary. except silB there could be a lot  of problems, say it feature extraction and so on. Try to decode mfc files you were training on to test recognition.

I want to use Julius because I'm running Julius in real-time, using it for a prototype which controls a robot in real-time by the voice. And to my knowledge HVite doesn't run in real-time. I don't think the problem comes from feature extraction because my mmf file, the dictionnary and and very basic grammar (i.e. S : COMMAND , where COMMAND is the whole dictionnary) work fine together with the old fashion way to launch recognition with Julian i.e. by specifiying in the Julius v4.0 command -h allwords.mmf -v allwords.dict -dfa allwords.dfa I was just curious if the recognition in isolated word mode works better for my purpose in Julius 4.0. Here are in attachment the dictionnary and the grammar. I have to ask if I can publish the mmf file because of legal reasons. Thanks a lot for your help.

Hi brunal2496,

I didn't see your last two submissions when I posted my last reply ... take a look at Step 1 in the tutorial, I think you need something like this in your grammar file:

S : NS_B COMMAND NS_E

then in your voca file you need to define NS_B and NS_E:

% NS_B
<s>        sil

%
NS_E
</s>        sil 

Using the Julius <s> and </s> defaults for silence word. 

Ken
