## Grammar definition file (DFA and dictionary)
##

#### There are three ways to specify the grammar files.
#### (1) and (2) can be used multiple times.

#### (1) Specify by common prefix of .dfa and .dict files. Comma-separated
#### prefixes can be specified for multiple grammar recognition
#-gram /cdrom/testrun/sample_grammars/vfr/vfr

#### (2) Or you can give Julian a text file which contains list of grammar
#### prefixes one per line.
#-gramlist file

#### (3) Classic way to specify a grammar.
-dfa sample.dfa
-v sample.dict

#### If you want to clear previously specified grammars, use this at the
#### point.
#-nogram

##
## Acoustic HMM file
##
# support ascii hmmdefs or binary format (converted by "mkbinhmm")
# format (ascii/binary) will be automatically detected
-h ../acoustic_model_files/hmmdefs

## triphone model needs HMMList that maps logical triphone to physical ones.
-hlist ../acoustic_model_files/tiedlist

## Context-dependency handling will be enabled according to the model type.
## Try below if julius wrongly detect the type of hmmdefs
##
#-no_ccd                # disable context-dependency handling
#-force_ccd             # enable context-dependency handling

## 
## If julius go wrong with checking parameter type, try below.
##
#-notypecheck
