Offline Speech Recognition With PocketSphinx

Follow the below steps to run AndroidPocketSphinxDemo project provided by Sphinx community:

1. Download the latest version of sphinxbase from the following link:
    http://sourceforge.net/projects/cmusphinx/files/sphinxbase/
    Extract the downloaded tar file and save it under a folder called 'sphinx' .

2. Download the latest version of pocketsphinx from the link:
    http://sourceforge.net/projects/cmusphinx/files/pocketsphinx
    Extract the downloaded tar file and save it under a folder named 'sphinx' .

3. After extracting sphinxbase and pocketsphinx, you will have to install both 
    in your system through the following commands,
  •     cd <sphinxbase path or pocketsphinx path>
  •     ./configure
  •     make
  •     make install
4. Make sure that you have installed Android NDK, if not installed, refer
    the link:
    http://developer.android.com/sdk/ndk/index.html

5. Download AndroidPocketSphinxDemo project from the link:
    https://github.com/cjac/cmusphinx/tree/trunk/PocketSphinxAndroidDemo

6. Copy the following files from <pocketsphinx path>/swig/edu/cmu/pocketsphinx
    to PocketSphinxDemo/jni/edu.cmu.pocketsphinx. The required files are:
  •     Config.java
  •     Decoder.java
  •     Hypothesis.java
  •     pocketsphinx.java
  •     pocketsphinxJNI.java
  •     SegmentIterator.java


7. Specify the path of 'sphinx' folder containing pocketsphinx and sphinxbase in
    'Android.mk' file. Then do Ndk build.

8. In the emulator/device in which you are going to install the project, create the
    folder called 'edu.cmu.pocketsphinx' under the path '/sdcard/Android/data/' .
   
9. Under the folder 'edu.cmu.pocketsphinx', create two folders called 'hmm' and
    'lm'. Under both 'hmm' and 'lm' create folder called 'en_US'.

10. Inside '/sdcard/Android/data/edu.cmu.pocketsphinx/hmm/en_US', copy the
      folder 'hub4wsj_sc_8k' present under   
      <pocketsphinx path>/model/hmm/en_US

11. Inside  '/sdcard/Android/data/edu.cmu.pocketsphinx/lm/en_US', copy the files
      'hub4.5000.dic' and 'hub4.5000.DMP' present under
      <pocketsphinx path>/model/lm/en_US

12. Now the project is ready to run on the emualtor/device.

    Which version of pocketsphinx did you download? It seems that the 0.6.1 version doesn't include the swig folder referenced in your tutorial.

    It looks like the swig file is only in the snapshot directory:

    Hi nickruiz,

    I have mentioned about pocketSphinx version:0.6.1

    Swig folder will be generated after step 3.

    ReplyDelete
  6. UnknownMarch 1, 2011 at 1:12 AM

    The swig folder wasn't created after I completed step 3, unfortunately. I ended up using the swig folder from the link I mentioned above and tried to reconfigure/rebuild the sphinxbase and pocketsphinx libraries.

    Unfortunately, when I try to build in step 7, I still get errors that I'm missing sphinxbase/err.h and pocketsphinx.h. Any ideas?

  7. Swathi EPMarch 1, 2011 at 3:30 AM

    Did you check whether there were any errors while installing sphinxbase and pocketsphinx through commands ./configure
    make
    make install

  8. UnknownMarch 1, 2011 at 5:04 AM

    Thanks again. I solved those problems. I had to make sure that my LOCAL_C_INCLUDES were pointing to the right locations. Now I have a bizarre set of errors related to ARM registers.

    elected processor does not support `smull r1,r2,r0,r4'

    I'm now asking on the Sphinx (SourceForge) forums: http://sourceforge.net/projects/cmusphinx/forums/forum/5471/topic/4390960?message=9490202

    I used the tarball that was posted on the Stack Overflow thread that you had used.
    http://www.zachrattner.com/PocketSphinxDemo.tar.gz

    It works until I try to compile it on my own machine. I still get the strange assembly errors. I posted a question on StackOverflow.

  14. UnknownMarch 13, 2011 at 6:29 AM

    @Nitin, I had to grab some folders from the "bleeding edge" version of PocketSphinx to get the swig folder. Apparently, the folder is supposed to be created automatically when you build, but that didn't work for me.

    Which SDK version of Android are you using? If you're using 2.2 or higher, you'll have to use /mnt/sdcard/ to access your external storage. Are you trying to run the code on the emulator, or on a phone?

    ReplyDelete
  15. UnknownMarch 13, 2011 at 11:49 AM

    thanks for the quick reply

    i am trying to run the code on the emulator first and it is running on 2.2.

    But i want to get it running on the phone which is running on 2.1. But I guess i will have to update the firmware to 2.2 . But i dont know where to find /mnt/sdcard/ folders....is there any way to find /sdcar/android/data command/folders. I have no clue how to get past this. Thanks for your help.

    If the swig folder wasn't created after you completed step 3, you maybe want to rename
    sphinxbase-X.X to sphinxbase by typing

    > mv sphinxbase-X.X sphinxbase (where X.X being the version of sphinxbase)

    Hi, yes i did that and it compiled perfectly. Now when i run the app in the emulator and i press the hold and speak button, the app crashes (exits). I know i have to do something with the /sdcard/android....
    i am just not sure where to find this path and how to do this! please help!

    hi Nithin,

    As i saw your comments above, i understood that you are running the code in emulator. So, get into "adb shell" of the emulator and there you can do "cd /sdcard/android", inside this directory run steps starting from 8 to 11.

  20. UnknownMarch 16, 2011 at 1:10 PM

    Nickrulz. I am in the same boat as you are in. I went got the bleeding edge source and did a ./autogen.sh and a ./configure. The ./configure complained that sphinxbase headers were not found. Where did you go to change the LOCAL_C_INCLUDES? In fact have you gotten it working yet, or are you still stuck at your last comment?

  21. UnknownMarch 16, 2011 at 2:05 PM

    By using both sphinxbase and pocketshpinx snapshots I have the swig folder that I need and no .h files missing. But the contents in /swig/edu/cmu/pocketsphinx are different than what you describe. I have ConfigTest.java,
    DecoderTest.java,
    goforward.wav,
    LatticeTest.java
    and test.cfg.

    It was someone on IRC who told me to get both snapshots of sphinxbase and pocketsphinx

    Also I was getting an error when trying to ndk-build -B the jni folder. I found out that you have to reverse the order the static-libraries are listed when building the shared library. So the last two lines look like this for me.

    LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil

    include $(BUILD_SHARED_LIBRARY)

    If I didn't reverse the order of the files it would complain about undefined references when trying to build the shared-library.

    The Java files (Config.java, Decoder.java, Hypothesis.java, etc.) don't seem to be in /swig/edu/cmu/pocketsphinx anymore, either in the 0.7 release or in the snapshots. Does anyone know where I can get these files?

  30. AlbertApril 18, 2011 at 8:14 AM

    I got the Java files to appear in [pocketsphinx directory]/swig/edu/cmu/pocketsphinx by:

    0. install swig (sudo apt-get install swig)
    1-3. as written above.
    3.1. cd [pocketsphinx directory]/swig
    3.2. make

    Don't know if the rest of the steps will work, trying now.

    dear Swathi;
    i have a problem in running ndk inside eclipse i think it is the problem when i specify the location to my ndk
    my location is: /home/amal/Desktop/senior_project/android-ndk-r3/build/host-setup.sh

    is this a correct path or i am missing something
    i am also having errors such as:
    Refresh Scope invalid
    and errors occurred during the build

    thanks

  33. Swathi EPApril 19, 2011 at 11:15 PM

    Hi Amal,

    Even i was facing "Refresh scope invalid", its because eclipse takes few minutes to refresh workspace and before it gets refreshed if you run the project, you will face such error. To resolve it, i was just refreshing for a minute, then the error got resolved.

    I may not be correct, if its wrong forgive me.

    In the above commands,
    TestJni - Project folder

    Dear Swathi,

    I got the pocketsphinx android demo to work. However, it runs very slowly - usually anywhere between 10x and 50x realtime to generate a final hypothesis. Then again, I'm running it on an HTC Dream (the slow-as-molasses original Android phone). How long does it take to run on your Droid? And how accurate is it?

    Thanks,

    Hi Albert,

    I tested PocketSphinxAndroidDemo in HTC Sprint, with the default dictionary of pocketSphinx, i was able to get 70% accuracy. Then i used:

    http://cmusphinx.sourceforge.net/wiki/tutoriallm

    tutorial in the above link to develop my own corpus using webService(lmtool) to generate language model and a dictionary files. This gave me around 95% accuracy.

    Hey Swathi, i followed these steps both on Windows(cygwin) and Backtrack(GNU/Linux), When i try to use the command NDK-BUILD, It asks for the project folder instead of the root folder where pocketsphinx and sphinxbase is, i even tried it on PocketSphinxDemo folder but it returns with an error saying target pattern contains no "%".

    Also step three has to be done on sphinxbase first and then pocketsphinx or just one of them? I did it in this order and it worked.(i guess).

    I tried to run the project on the emulator and it ran without errors but as soon as the dialog appears the app closes without any notification.

    Also Lastly how can we deploy this an app? as in we need to put these files together and then create a folder in the sd card using the code ? Is it possible ?

    And amar please help me set this up using eclipse if you can

    *In the emulator/device in which you are going to install the project, create the
    folder called 'edu.cmu.pocketsphinx' under the path '/sdcard/Android/data/'

    Is this method apt for the Windows operating system? As far as I know there in no make and makefile in windows. Is there a way to make a similar thing work on Windows?

      Charindu, I am assuming the sourceforge project is a complete android project. If so how can I download your files from sourceforge

    It's working if
    1) i download snapshot pocketsphinx, sphinxbase.
    2) i have installed
    sudo apt-get install libtool
    sudo apt-get install autoconf
    sudo apt-get install automake
    sudo apt-get install swig
    sudo apt-get install bison

    When I key "make" and "sudo make install", I don't get all file. For this, it is necessary the following...

    1.- cd [pocketsphinx directory]/swig
    2. make

    I have tried the PocketSphinxDemo file that download from the main site. Everything are fine except RecognizerTask.java. It shows 2 error which are config() and Decoder(c). These two function can import at first, but when it used, error occurs as undefined. Help me to solve this problem please. Thanks a lot.

    hi is there any need to compile with swig if we didn't change in demo project in window as swig file already in demo project and we have to generate only .so file and change in .mk file .

    I mean to say need to use of step 3
    3. After extracting sphinxbase and pocketsphinx, you will have to install both
    in your system through the following commands,

    cd
    ./configure
    make
    make install

    Hello, we are part of a research group in the American University of Beirut. We are working on building pocketsphinx on Android. When we import the project to eclipse, however, we get the error:"duplicate src in project". The problems shown are: "The project was not built since its build path is incomplete."
