NAME

       sphinx_fe - Convert audio files to acoustic feature files

SYNOPSIS

       sphinx_fe [ options ]...

DESCRIPTION

       This  program  converts  audio  files  (in  either Microsoft WAV, NIST Sphere, or raw format) to acoustic
       feature files for input to batch-mode speech recognition.   The  resulting  files  are  also  useful  for
       various other things.  A list of options follows:

       Currently the only kind of features supported are MFCCs (mel-frequency cepstral coefficients).  There are
       numerous options which control the properties of the output features.  It  is  VERY  important  that  you
       document  the specific set of flags used to create any given set of feature files, since this information
       is NOT recorded in the files themselves, and any mismatch between the parameters used to extract features
       for recognition and those used to extract features for training will cause recognition to fail.
