jcontrol
jcontrol
- a sample module client written in C
jcontrol {hostname} [portnum]
jcontrol is a simple console program to control julius
running on other host via network API. It can send command to Julius, and
receive messages from Julius.
When invoked, jcontrol tries to connect to Julius running in
"module mode" on specified hostname. After connection established,
jcontrol waits for user commands from standard input.
When user types a command to jcontrol, it will be interpreted and
cor- responding API command will be sent to Julius. When a message is
received from Julius, its content will be output to standard output.
For the details about the API, see the related documents.
hostname
Host name where Julius is runnning in module mode.
portnum
port number (default: 10500)
jcontrol interprets commands from standard input. Below is
a list of all commands.
pause
Stop Julius and enter into paused status. In paused
status, Julius will not run recognition even if speech input occurs. When this
command is issued while recognition is running, Julius will stop after the
recognition has been finished.
terminate
Same as pause, but discard the current speech input when
received command in the middle of recognition process.
resume
Restart Julius that has been paused or terminated.
inputparam arg
Tell Julius how to deal with speech input in case grammar
is changed just when recognition is running. Specify one:
"TERMINATE", "PAUSE" or "WAIT".
version
Tell Julius to send version description string.
status
Tell Julius to send the system status (active /
sleep)
changegram prefix
Send a new grammar "prefix.dfa" and
"prefix.dict", and tell julius to use it as a new grammar.
All the current grammars used in the current process of Julius will be deleted
and replaced to the specifed grammar.
addgram prefix
Send a new grammar "prefix.dfa" and
"prefix.dict" and add it to the current grammar.
deletegram gramlist
Tell Julius to delete existing grammar. The grammar can
be specified by either prefix name or number ID. The number ID can be
determined from the message sent from Julius at each time grammar information
has changed. When want to delete more than one grammar, specify all of them as
comma-sparated.
deactivategram gramlist
Tell Julius to de-activate a specified grammar. The
specified grammar will still be kept but will not be used for recognition.
The target grammar can be specified by either prefix name or
number ID. The number ID can be determined from the message sent from Julius
at each time grammar information has changed. When want to delete more than
one grammar, specify all of them as comma-sparated.
activategram gramlist
Tell Julius to activate previously de-activated grammar.
The target grammar can be specified by either prefix name or number ID. The
number ID can be determined from the message sent from Julius at each time
grammar information has changed. When want to delete more than one grammar,
specify all of them as comma-sparated.
addword grammar_name_or_id dictfile
Add the recognition word entries in the specified
dictfile to the specified grammar on current process.
syncgram
Force synchronize grammar status, like unix command
"sync".
Julius-4 supports multi-model recognition nad multi decoding. In
this case it is possible to control each recognition process, as defined by
"-SR" option, from module client.
In multi decoding mode, the module client holds "current
process", and the process commands and grammar related commands will be
issued toward the current process.
listprocess
Tell Julius to send the list of existing recognition
process.
currentprocess procname
Switch the current process to the process specified by
the name.
shiftprocess
Rotate the current process. At each call the current
process will be changed to the next one.
addprocess jconffile
Tell Julisu to load a new recognition process into
engine. The argument
jconffile should be a jconf file that contains
only one set of LM options and one SR definition. Note that the file should be
visible on the running Julius, since
jcontrol only send the path name
and Julius actually read the jconf file.
The new LM and SR process will have the name of the jconffile.
delprocess procname
Delete the specified recognition process from the
engine.
deactivateprocess procname
Tell Julius to temporary stop the specified recognition
process. The stopped process will not be executed for the input until
activated again.
activateprocess procname
Tell Julius to activate the temporarily stopped
process.
The dump messages from Julius are output to tty with prefix
">" appended to each line. Julius can be started in module mode
like this:
jcontrolcan be launched with the host name:
It will then receive the outputs of Julius and output the raw
message to standard out. Also, by inputting the commands above to the
standard input of jcontrol, it will be sent to Julius. See manuals
for the specification of module mode.
