Installing Pocketsphinx on Android

Question

I have some questions on installing Pocketsphinx on and Android phone, and I haven't been able to find answers on CMUSphinx's support forum, IRC, existing StackOverflow posts, or intensive Googling. If anyone here has a minute and would be willing to help, I'd greatly appreciate it.

First off, I'm confused as to whether I can even install Pocketsphinx on Android. I believe I need Java bins in order to run on Android, so I attempted to install Sphinx 4. To test the program, I made an empty activity and moved the HelloWorld demo file into the onCreate method.

Then, I added the following libraries to the build path:

• js.jar
• jsapi-1.0-base.jar
• junit-4.8.1.jar
• sphinx4.jar
• tags.jar
• WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar

The code deploys on a Droid 2 running Android 2.2, but I get the following error at runtime:

ERROR/AndroidRuntime(11567): Caused by: Property exception component:'wsjLoader' property:'location' - Can't locate resource:/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz

I am including that jar file in the build path, so I'm not sure why that's causing an exception to be thrown. But then again, I'm not even sure I should be trying to install Sphinx 4 on Android. Does anyone know what I should do? Thanks in advance for your help.

5/2011 Update: The attempt I made to get pocketsphinx to run on Android is now listed on the CMU Sphinx wiki at http://cmusphinx.sourceforge.net/2011/05/building-pocketsphinx-on-android/

Answer 1

Not sure if you had this figured out but I have not read anywhere that you had to do this. So in case you are still having problems running PocketSphinx on the Android, what you need to do is to create the folders and upload the acoustics and language models to the locations specified in RecognizerTask.java.

Answer 2

Pocketsphinx on Android has been updated many times since then and got new features and capabilities. You can find the latest installation how to here:

There is no need to do any complex installation now, you can just import the project in ADT and it should work.
