Using JSGF grammar instead of DMP language model (use -jsgf instead of -lm) in CMU Sphinx (pocketsphinx)

Question

I need to train CMU Sphinx offline in my android app. I downloaded this project that use this parameter but when I start it I have this error: Fatal signal 11 (SIGSEGV) at 0x0000001c (code=1). This error I also have when Sphinx can not find the accoustic model. I found answer on my question here, but it is does not work for me. What I am doing wrong, can anybody can provide me any tutorial, or a good answer?

So the question is how to use .jsgf files istead of .DMP files as language model for Pocketsphinx like it used in Recognizer task in Inimesed project?

Answer 1

If CMU Sphinx works similarly on Android and on Windows, the following may help:

Example JSGF file:

#JSGF V1.0;
grammar hello;
public <command> = ( open | close ) ( computer | window | music | note );

Save the above grammar in a text file called "hello.gram", then run sphinx with:

pocketsphinx_continuous.exe -hmm hub4wsj_sc_8k -jsgf hello.gram -dict hub4.5000.dic
