I want to create a voice recognition application using the pocketsphinx-android-demo-5prealpha. I only need this app to work with Spanish.
I replaced the default acoustic and language models with the Spanish packet of voxforge (voxforge-es-0.2.tar.gz).
In English, by default the app works correctly in my phone: Samsung Galaxy S4 (i9505) with Android KitKat 442.
When I replace the language and acoustic corpus and I recompile the project the app crashes and I obtain the next error via logcat. I changed the "KEYPHRASE" to "comenzar" (meaning "start" or "start up") to test the app too.
Here is the error:

Where is the problem? I don't change any method, variable or kind of code.
