    Hello all,

    1)
    I have a problem doign the preliminary decode; I'm using the rm1 files. I tried running the commad :
    "perl scripts_pl/decode/slave.pl" form the rm1 directory and form the scripts_pl directory but I get an erros that says: "can't open perl script no such file or directory found"

    I have some slave files but they are inside the the folders of scrpts_pl. For example on the folder "02.falign_ci_hmm" I have a "slave_convg.pl" should I decode each of these slave files one by one ? Did I do something worng on the last step?

    2)
    On the prelominary training run I followed the steps. Some errors showed up on the HTML file that was generated. Here is one of these errors. Is this something I should be concerned with? is this why I cant find that salve file?

    ERROR:

    norm Log File completed
    Current Overall Likelihood Per Frame = -7.49851970809299
    Convergence Ratio = 0.324217846210801

    Thanks,

      Here is an error I get when I try to decode slave files such as "slave_convg.pl"

      "Configuration (e.g. etc\sphinxtrain.cfg) not defined" I'm trying to go back to define this configuration but I coan't find how. I tried doing :
      "$CFG_QUEUE_TYPE = "Queue::POSIX";" but it tells me that "$CFG_QUEUE_TYPE" is not recognized as an internal or external command.

      Then there is really no such script. You have to setup decoder first or use correct slashes. Follow the tutorial please.

      It's ok for beginning to have errors, they usually means that transcription is not correct. For better error reason look into the logs in logdir folder.

      Hello Nicklay,

      1)
      I'm still trying to decode the data. I'm unable to find the folder named "decode" is there a reason why?

      2)
      I'm running windows so I can't run SCLITE for my WER since SCLITE is for Linux correct? I found a word alignment tool; but if you can suggest one that you've tested and you know works fine I'd like to use it. Please let me know.

      Thank you

        Did you forget to setup the decoder? See http://www.speech.cs.cmu.edu/sphinx/tutorial.html#setupdecode

        It's a very simple program, it should work under Windows too but I'm not sure how to get it. Probably you have to compile it yourself. Move to Linux better :)

          I think setting up the decoder might be my problem as to why my decoder folder is missing.

          1) I'm using Sphinx-4(java version of sphinx)
          2) I intalled the decoder and I'm able to run the demos on it such as "helloworld"
          3) Question:

          1) Do I need to setup the tutorial by copying all relevant executables and scripts to the same area as the data? Since I'm using Sphinx-4 and it is mentioned in the tutorial that the section is forthcoming for this particular version, I suspect I did something worng at that step.

          I've gone back and I have redone the tutorials and the decode folder does not appear. In addition, I started using cygwin, is that better than using DOS? It did not help with the decode folder though.

            That's the problem. As tutorial mentions "Section forthcoming." I suppose this work is not finished at all and it would be rather problematic to use sphinx4 for a new database evaluation. Why don't you try with sphinx3 or pocketsphinx? They should compile fine under Cygwin.

              OK. I think I will try one of those then. Thank you for your help.
