    @mrjj i have installed cmu-sphinx and pocketsphinx using the instructions given in this link http://jrmeyer.github.io/installation/2016/01/09/Installing-CMU-Sphinx-on-Ubuntu.html is it correct ?

    If yes, where i will get the lib of this and how to use this lib to make use of voice recognition ?

    It seems like a good tut.

    When you compile you will get the lib
    and this lib you will use in the real project.

        Im not sure if it comes with a .pro file?
        Its should be clear from build instructions what to do
        on each platform.

        sudo make install
        That will copy the "result" (exe, .a ) to a place so its installed.

          @mrjj

          The tut you found is not Qt related so its with normal linux toolchain
          for CMU-Sphinx.

          He starts with
          "When I installed SPHINX for the first time in September 2015, it was not a fun experience."

          So be prepared to really read what he does and read docs for it. its not trivial to build.

              First you get it to build then
              use in Qt. its in 2 steps.
              You really MUST read docs slow and carefully ,
              else u miss a step and it wont work.

              So first step is to get it to build using the tuts.

                    The tut you found seemed good?
                    http://jrmeyer.github.io/installation/2016/01/09/Installing-CMU-Sphinx-on-Ubuntu.html

                    So if you have build the so files you are to use them
                    This part mostly fails due to paths so make sure u check.

                    You can open .pro file then, in open file, right click and select
                    Add library. Fill it out and make sure!! its correct.
                    Linux lib, shared etc.

                    http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

                    Then you should be able to link against it.

                      https://github.com/cmusphinx/pocketsphinx

                      Same story with pocket

                      http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

                      also MAKE 100% sure you did as it says

                      "Prerequisites

                      You must have SphinxBase, which you can download from http://cmusphinx.sourceforge.net. Download and unpack it to the same parent directory as PocketSphinx, so that the configure script and project files can find it. On Windows, you will need to rename 'sphinxbase-X.Y' (where X.Y is the SphinxBase version number) to simply 'sphinxbase' for this to work."

                              Well if all works and says no "error" of any kind,
                              I would try one of the existing examples
                              and see if it works.

                              Then I would start think about how to use it in Qt.

                                    @mrjj u said I would try one of the existing examples
                                    and see if it works. where i can get existing examples ?
