-.SH NAME
-jconf
-\- Jconf configuration file specification
-.SH DESCRIPTION
-The variables that can be written in Jconf file are organized as follows.
-.TP 0.2i
-\(bu
-Global options
-.TP 0.2i
-\(bu
-Instance declaration
-.TP 0.2i
-\(bu
-Language model instance
-.TP 0.2i
-\(bu
-Acoustic model and speech analysis instance
-.TP 0.2i
-\(bu
-Recognizer and search instance
-.PP
-The details are described in the followings.
-.SH EXAMPLE
-These are examples of jconf file.
-.PP
-First example is a simple one with no instance declaration. When
-no instance declaration is found, Julius assumes there are only
-one AM, LM and recognition process instance. In this case, the
-default instance will be named "\fB_default\fR", and
-option order does not matter. This is equivalent to older version
-of Julius, except for GMM handling (see below).
-.PP

- (\fILM options\fR...)
- (\fISearch options\fR...)
-
-.fi
-.PP
-This is an example using two acoustic models and three language
-models of different types. Three recognition process instance is
-defined for each combination of AM and LM. The LM type (ngram /
-grammar / word) is determined by the arguments. The Global
-options are placed at the top in the example, but actually it can
-be placed anywhere in the file.

-.fi
-.PP
-This is another example using GMM for frontend processing. Note
-that from Rev.4.0 Julius has independent MFCC calculation scheme
-for GMM. This means that you should explicitly specify the
-acoustic analysis condition for GMM, not only the AM.
-.PP
-Option \fB\-AM_GMM\fR switch the current AM configuration
-to the one prepared internally for GMM. You can place AM configuration
-after the option to specify MFCC computation parameter for GMM.
-If you define exactly the same condition as AM for recognition,
-the same MFCC calculation instance will be shared among AM and GMM.
-Else, each MFCC will be computed independently.

-.RS
-.SS "Audio input"
-.RE
-.TP
-\fB\-input \fR\fB{mic|rawfile|mfcfile|adinnet|stdin|netaudio} \fR
-Choose speech input source. 'file' or 'rawfile' for waveform
-file, 'htkparam' or 'mfcfile' for HTK parameter file. Users will
-be prompted to enter the file name from stdin, or you can use
-"\-filelist" option to specify list of files to process.
-
-\&'mic' is to get audio input from live microphone device, and
-\&'adinnet' means receiving waveform data via tcpip network from
-an adinnet client. 'netaudio' is from DatLink/NetAudio input,
-and 'stdin' means data input from standard input.
-
-For waveform file input, only WAV (no
-compression) and RAW (noheader, 16bit,
-big endian) are supported by default. Other format can be read
-when compiled with \fBlibsnd\fR library. To see
-what format is actually supported, see the help message using
-option "\-help". For stdin input, only WAV and RAW is
-supported. (default: mfcfile)
-.TP
-\fB\-filelist \fR\fIfilename\fR
-(With \-input rawfile|mfcfile) perform recognition on all files
-listed in the file. The file should contain an input file
-per line. Engine ends when all of the files are processed.
-.TP

-matches the AM or not. This option will disable the check and
-use the input vector as is.
-.TP
-\fB\-48 \fR

-Julius by default removes successive zero samples in input
-speech data. This option inhibits this removal.
-.TP
-\fB\-zmean \fR, \fB\-nozmean \fR
-This option enables/disables DC offset removal of input
-waveform. Offset will be estimated from the whole input. For
-microphone / network input, zero mean of the first 48000
-samples (3 seconds in 16kHz sampling) will be used for the
-estimation. (default: disabled)
-
-This option uses static offset for the channel. See also
-\fB\-zmeansource\fR for frame\-wise offset removal.

-.SS "Input rejection by average power"
-.RE
-.PP
-This feature will be enabled by

-used with Decoder VAD or GMM VAD. Valid for real\-time input only.
-.TP
-\fB\-powerthres \fR\fIthres\fR
-Reject the inputted segment by its average energy. If the
-average energy of the last recognized input is below the
-threshold, Julius will reject the input. (Rev.4.0)
-
-This option is valid when
-\fB\-\-enable\-power\-reject\fR is specified
-at compilation time.
-.RS
-.SS "Gaussian mixture model"
-.RE
-.PP
-GMM will be used for input rejection by accumurated score, or for
-GMM\-based frontend VAD when \fB\-\-enable\-gmm\-vad\fR is specified.
-.PP
-NOTE: You should also set the proper MFCC parameters required for the
-GMM, specifying the acoustic parameters described in AM section
-\fB\-AM_GMM\fR.
-.TP
-\fB\-gmm \fR\fIhmmdefs_file\fR
-GMM definition file in HTK format. If specified, GMM\-based
-input verification will be performed concurrently with the 1st
-pass, and you can reject the input according to the result as

-defined as one\-state HMMs.
-.TP
-\fB\-gmmnum \fR\fInumber\fR
-Number of Gaussian components to be computed per frame on GMM
-calculation. Only the N\-best Gaussians will be computed for

-2) may cause degradation of identification performance.
-.TP
-\fB\-gmmreject \fR\fIstring\fR
-Comma\-separated list of GMM names to be rejected as invalid
-input. When recognition, the log likelihoods of GMMs
-accumulated for the entire input will be computed concurrently

-input will be rejected.

-1st pass decoding. By default, real\-time processing on the pass is on
-for microphone / adinnet / netaudio input, and for others.
-.TP
-\fB\-realtime \fR, \fB\-norealtime \fR
-Explicitly switch on / off real\-time (pipe\-line) processing on
-the first pass. The default is off for file input, and on for
-microphone, adinnet and NetAudio input. This option relates
-to the way CMN and energy normalization is performed: if off,
-they will be done using average features of whole input. If
-on, MAP\-CMN and energy normalization to do rea\-time processing.
-.SS "INSTANCE DECLARATION FOR MULTI DECODING "
-The following arguments 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.
-.PP
-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.
-.PP
-When no instance definition is found (as older version of Julius),
-all the options are assigned to a default instance named "_default".
-.PP
-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 following.

- \-AM am_1 \-AM am_2
- \-LM lm (LM spec..)
- \-SR search1 am_1 lm
- \-SR search2 am_2 lm
-.fi
-
-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:
-
-.nf
-
- \-AM am_1 \-AM am_2
- \-LM lm_1 (LM spec..)

-\fB\-SR \fR\fIname\fR \fIam_name\fR \fIlm_name\fR
-Create a new search configuration set, and switch current to
-the new one. The specified AM and LM will be assigned to it.
-The \fIam_name\fR and
-\fIlm_name\fR can be either name or ID
-number. You should give a unique name. (Rev.4.0)
-.TP
-\fB\-AM_GMM \fR
-A special command to switch AM configuration set for
-specifying speech analysis parameters of GMM. The current AM
-will be switched to the GMM specific one already reserved, so
-be careful not to confuse with normal AM configurations.
-(Rev.4.0)
-.SS "LANGUAGE MODEL (\-LM) "

-ARPA format. When both a forward N\-gram and backward N\-gram
-are specified, Julius uses this forward 2\-gram for the 1st
-pass, and the backward N\-gram for the 2nd pass.
-
-Since ARPA file often gets huge and requires a lot of time to
-load, it may be better to convert the ARPA file to Julius
-binary format by mkbingram. Note that if
-both forward and backward N\-gram is used for recognition, they
-together should be converted to a single binary.
-
-When only a forward N\-gram is specified by this option and no
-backward N\-gram specified by \fB\-nrl\fR, Julius
-performs recognition with only the forward N\-gram. The 1st

-forward probabilities to backward probabilities by Bayes rule.
