       -fsgusefiller

       -fwd3g Use trigrams in first pass search

       -fwdflat
              Run forward flat-lexicon search over word lattice (2nd pass)

       -fwdflatbeam
              Beam width applied to every frame in second-pass flat search

       -fwdflatefwid
              Minimum number of end frames for a word to be searched in fwdflat search

       -fwdflatlw

       -hmm   containing acoustic model files.

       -hyp   output file name

       -hypseg
              output with segmentation file name

       -input_endian

       -kdmaxbbi
              Maximum number of Gaussians per leaf node in kd-Trees

       -kdmaxdepth
              Maximum depth of kd-Trees to use

       -kdtree

       -latsize
              Lattice size

       -lifter

       -live  Get input from audio hardware

       -lm    trigram language model input file

       -lmctl a set of language model

       The -hmm and -dict arguments are  always  required.   Either  -lm  or  -fsg  is  required,
       depending on whether you are using a statistical language model or a finite-state grammar.
       To do batchmode recognition, you will need to specify a control file, using -ctl This is a
       simple  text  file containing one entry per line.  Each entry is the name of an input file
       relative to the -cepdir directory, and without the filename extension (which is  given  in
       the -cepext argument).

       If  you are using acoustic feature files as input (see sphinx_fe(1) for information on how
       to generate these), you can also specify a subpart of a file, using the following format:

              FILENAME START-FRAME END-FRAME UTTERANCE-ID
