Voice Recognition Implementation

Naveen_D

@mrjj I am getting output for his next sample(Rhythm Box).

mrjj

@Naveen_D
Super. so it can work :)

Naveen_D

@mrjj ya for those samples it is working fine...but when i generate my own .grammar and .voca file with same procedure i am not getting output it is showing me errors..i am following the steps as it is...but no output. i am not getting what is going wrong..:-(

mrjj

@Naveen_D
Well dont the errors give any hints of what it dont like?

Naveen_D

@mrjj no...it is showing
ubuntu@ub:~/Documents/julius-4.2.2/SampleTest$ padsp julius -C julian.jconf
STAT: include config: julian.jconf
ERROR: Error in loading model
ubuntu@ub:~/Documents/julius-4.2.2/SampleTest$

mrjj

Ok , can mean many things.

Example
" the model tied state triphone you use is not contain sp."

So , you should check the modification you make and read docs on each command. etc to avoid this.

@mrjj Now i want to use this julius in qt..how to use this..what i need to do?
can you please guide me in this matter..thanks

Hi Always good starting reading docs.
https://julius.osdn.jp/juliusbook/en/desc_install.html

% make install
"which also installes headers and libraries as well as the binaries."

It means that it should generate a .so ? or .a file file and some .h files
( u must understand types of libs possible)
http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html

you need to find out the exact names of those.

Then you need to add to a Qt project
http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

Make sure u fill it out correctly. Name wise.

Then you need find c++ example to see what functions to call etc.
and it should be it.

This might be ok sample

@mrjj u said,
make install
"which also installes headers and libraries as well as the binaries."=
It means that it should generate a .so ? or .a file file and some .h files

Now I have configured and i run make and make install commands
After running sudo make install command, where i can get these .so or .a file in system (means which path) ?

Naveen_D

Hi i got the .a and .h files and binaries also...after this when i am trying with the example i need to add the library file and do i need to add all the .h files to my example project ?

mrjj

@Naveen_D
Hi
Normally you add a new path where to look for .h
files but you can also just include them.

like in the pro file
INCLUDEPATH += ../testLib
LIBS += -L../testLib/debug -ltestLib

https://wiki.qt.io/How_to_create_a_library_with_Qt_and_use_it_in_an_application

(NOTE , you names is NOT testLIB)

With the .A files

@mrjj Hi i am bit confused after adding the library my .pro file is

#-------------------------------------------------
#
# Project created by QtCreator 2016-10-26T15:15:30
#
#-------------------------------------------------

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = ExampleJulius
TEMPLATE = app


SOURCES += main.cpp\
        mywidget.cpp

HEADERS  += mywidget.h

unix:!macx: LIBS += -L$$PWD/./ -ljulius

INCLUDEPATH += $$PWD/.
DEPENDPATH += $$PWD/.

unix:!macx: PRE_TARGETDEPS += $$PWD/./libjulius.a

is it correct ?

jsulm

@Naveen_D

unix:!macx: LIBS += -L$$PWD/./ -ljulius
unix:!macx: PRE_TARGETDEPS += $$PWD/./libjulius.a

You should not link against shared lib and static lib (.a) at the same time. Either use shared lib or static lib.
Does $$PWD/. contain the lib itself and the header files?

Naveen_D

@jsulm I have copied the lib file and .h files to my example project and then in qt creator added the lib externally...

jsulm

@Naveen_D So, did you try to execute qmake and to do a complete rebuild to check whether it works?

Naveen_D

@jsulm Also i added the .h files to my project...
Ya i cleaned, run qmake and builded, it worked fine and executed

Naveen_D

@jsulm But whenever i opened the .h files in qt creator at top it is showing...
Error: Couldnot decode "callback.h" with "utf-8"-encoding. Editing not possible

mrjj

@Naveen_D

hi , you need to fix the file.

http://doc.qt.io/qtcreator/creator-editor-options-text.html

"To resolve the issue, use a file conversion tool such as Recode to convert the file encoding to UTF-8 when developing Qt 5 applications. Otherwise, conversion of string constants to QStrings might not work as expected."

http://superuser.com/questions/116907/how-to-recode-to-utf-8-conditionally

The "recode-to-utf8.sh " post.

@mrjj Thanks...
Now i want know how to use the api's of julius..
I have developed a simple UI in qml in which i have developed simple icon with image and want to add voice recognition using julius...
Is it the rite way what i am doing now or there is any better way to achieve this?
how to do this..? guidance required..Thanks

Hi

I have developed a simple UI in qml in which i have developed simple icon with image and want to add voice recognition
Is it the rite way what i am doing now or there is any better way to achieve this?

Hi, using QML for Interface is fine idea but why not wait a bit before having to learn how to call c++ functions from
QML and for now focus on getting the recognition up and running using plain c++ GUI app for testing.
Anyway, should not be super involving.
http://doc.qt.io/qt-5/qtqml-cppintegration-topic.html

Then after you can call a c++ functions, its time to read the docs and study the sample.
