    Roberts - 2013-07-26

    I am trying to set up pocketsphinx to recognize speech from wav files. Recognition results are a lot worse, compared to results from sphinxtrain acoustic model evaluation results.

    If I use feature file instead of wav file, than the results are the same, so I assume, that the problem might be related to configuration of feature extraction, but I can't find it. Any suggestions?

    So here are all the files:

    etc/sphinx_train.cfg http://pastebin.com/DwcmiNbm

    etc/feat.params

        -nfilt __CFG_NUM_FILT__
        -lowerf __CFG_LO_FILT__
        -upperf __CFG_HI_FILT__
        -feat __CFG_FEATURE__
        -svspec __CFG_SVSPEC__
        -agc __CFG_AGC__
        -cmn __CFG_CMN__
        -varnorm __CFG_VARNORM__
    

    command I use for pocketsphinx_batch

    pocketsphinx_batch ^
