NAME
       pocketsphinx_continuous - Run speech recognition in continuous
       listening mode

SYNOPSIS
       pocketsphinx_continuous -hmm hmmdir -dict dictfile [ options ]...

DESCRIPTION
       This program opens the audio device and waits for speech.  When it
       detects an utterance, it performs speech recognition on it.

              'none')

       -cmninit
              Initial values (comma-separated) for cepstral mean when 'prior'
              is used

       -compallsen
              Compute all senone scores in every frame (can be faster when
              there are many senones)

       -ctl   file listing utterances to be processed

       -ctlcount
              No. of utterances to be processed (after skipping -ctloffset
              entries)

       -ctlincr
              Do every Nth line in the control file

       -ctloffset

       -fsgbfs
              Force backtrace from FSG final state

       -fsgctlfn
              finite state grammar control file

       -fsgusealtpron
              Use alternative pronunciations for FSG

       -fsgusefiller
              (FSG Mode (Mode 2) only) Insert filler words at each state.

       -fwd3g Use trigrams in first pass search

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

       -fwdflatefwid

       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.
