####  Valid for real-time input only.
####
#-powerthres 9.0		# reject input by avg. energy

####
#### Gaussian Mixture Model
####
####  GMM will be used for input rejection by accumurated score, or
####  for GMM-based frontend VAD when "--enable-gmm-vad" specified.
####
####  NOTE: If you use MFCC for the GMM which is different from AM, you
####  should also set the parameters like other AM with an option "-AM_GMM".
####  If "-AM_GMM" is not used, Julius assume GMM to use the same
####  parameter as the first AM.

####
#### Decoding option
####
#### Real-time processing means concurrent processing of MFCC computation
#### and 1st pass decoding.  By default, real-time processing on the
#### 1st pass is on for microphone / adinnet / netaudio input, and
#### off for others.
####
#-realtime			# force real-time processing
#-norealtime			# force non real-time processing

######################################################################
#### INSTANCE DEFINITION FOR MULTI DECODING
######################################################################
####
#### The following three argument will create a new configuration set
#### with default parameters, and switch current set to it.  Jconf
#### parameters specified after the option will be set into the current
#### set.
####
#### To do multi-model decoding, these argument should be specified at
#### the first of each model / search instances with different names.
#### Any options before the first instance definition will be IGNORED.
####
#### When no instance definition is found (as older version of Julius),
#### all the options are assigned to a default instance named "_default".
####
#### Please note that decoding with a single LM and multiple AMs is not
#### fully supported.  For example, you may want to construct the
#### jconf file as this:
####
####  -AM am_1 -AM am_2
####  -LM lm (LM spec..)
####  -SR search1 am_1 lm
####  -SR search2 am_2 lm
####
#### This type of model sharing is not supported yet, since some part
#### of LM processing depends on the assigned AM.  Instead, you can
#### get the same result by defining the same LMs for each AM, like this:
####
####  -AM am_1 -AM am_2
####  -LM lm_1 (LM spec..)
####  -LM lm_2 (same LM spec..)
####  -SR search1 am_1 lm_1
####  -SR search2 am_2 lm_2
####

## Create a new AM configuration set, and switch current to it.
## You should give a unique name.
#-AM name			

## Create a new LM configuration set, and switch current to it.
## You should give a unique name.
#-LM name			

## Create a new Search configuration set with AM and LM, and switch 
## current to it.  AM and LM name can be either name or ID number.
#-SR name am_name_or_id lm_name_or_id

## Switch current AM to special one reserved for GMM, to specify
## analysis parameter for GMM.  Be sure not to confuse with normal AM
## configuration.
# -AM_GMM

## When using instance declarations, global options should be placed
## at top before any instance declaration, or after this option below.
## This option is only a switcher and can be used anywhere anytime.
# -GLOBAL

## This option disables the strict section checkings and back to 4.0
# -nosectioncheck

######################################################################

#### ACOUSTIC MODEL (-AM)  (-AM_GMM)
######################################################################
####
#### Acoustic analysis parameters are included in this section, since
#### the AM defines the required parameter.  You can use different MFCC
#### type for each AM.
#### For GMM, the same parameter should be specified after "-AM_GMM"
#### 
#### When using multiple AM,  the values of "-smpPeriod", "-smpFreq",
#### "-fsize" and "-fshift" should be the same among all AM.
