cmusphinx - Why is pocketsphinx returning a null hypothesis via java with kws? Works via commandline, not via code -
i've been working pocketsphinx in java. i've pieced various sources.
trying keyword detection via pocketsphinx.
as stated works via command line:
pocketsphinx_continuous -inmic yes -kws keyphrase.list where keyphrase.list file contains:\
abomination /le-20/ i hit every time.
here java code:
( i've tried le-1 through le-40 )
import javax.sound.sampled.audioformat; import javax.sound.sampled.audiosystem; import javax.sound.sampled.dataline; import javax.sound.sampled.targetdataline; import java.io.bytearrayoutputstream; import java.io.ioexception; import java.nio.bytebuffer; import java.nio.byteorder; import java.util.arrays; import edu.cmu.pocketsphinx.decoder; import edu.cmu.pocketsphinx.config; import edu.cmu.pocketsphinx.hypothesis; public class controller { static { system.loadlibrary("pocketsphinx_jni"); } private static bytearrayoutputstream out; public static void main(string args[]) { audioformat format = new audioformat(44100, 16, 1, true, true); targetdataline targetline = null; dataline.info targetinfo = new dataline.info(targetdataline.class, format); boolean running = true; try { targetline = audiosystem.gettargetdataline(format); targetline.open(); out = new bytearrayoutputstream(); int numbytesread; byte[] data = new byte[targetline.getbuffersize() / 5]; config c = decoder.defaultconfig(); c.setstring("-hmm", "/usr/local/share/pocketsphinx/model/en-us/en-us/"); //c.setstring("-lm", "/usr/local/share/pocketsphinx/model/en-us/en-us.lm.bin"); c.setstring("-dict", "/usr/local/share/pocketsphinx/model/en-us/cmudict-en-us.dict"); c.setstring("-keyphrase", "abomination"); c.setfloat("-kws_threshold", 1e-1); decoder d = new decoder(c); d.setrawdatasize(300000); targetline.start(); system.out.println("recorder started"); byte[] b = new byte[4096]; d.startutt(); system.out.println("decoder started"); while ((running)) { int nbytes; short[] s = null; nbytes = targetline.read(b,0,b.length); bytebuffer bb = bytebuffer.wrap(b, 0, nbytes); s = new short[nbytes/2]; bb.asshortbuffer().get(s); d.processraw(s, nbytes/2, false, false); d.setkws("abomination", ); if (nbytes > 0) { hypothesis hypothesis = d.hyp(); if (hypothesis != null) { system.out.println("------------------------------------------------------"); system.out.println(hypothesis.gethypstr()); system.out.println("------------------------------------------------------"); d.endutt(); d.startutt(); } } } } catch (exception e) { system.err.println(e); } } } code runs fine. never enters if if(hypothesis != null) reason.

also if intend use kws there no need use -lm in arguments. need remove: "-lm", ".../model/hub4wsj_sc_8k_adapt/etc/hub4.5000.dmp",
that answers that.
if change above code , remove:
c.setstring("-keyphrase", "abomination"); and add:
c.setstring("-kws", "/home/pennyworth/keyphrase.list"); now output shows -kws set
-kws /home/pennyworth/keyphrase.list and in output:

here api doc pocketsphinx, http://cmusphinx.sourceforge.net/doc/pocketsphinx/pocketsphinx_8c_source.html
i don't know how move forward this. i'm either not setting decoder correctly or else happening , thats why i'm getting null return.
i'm not clear on use of -kws vs -keyphrase vx -kws-threshold. using -kws mean don't need other 2 since sets both phrase , threshold?
updated code. added byteorder. ( , made sure 1 wasn't l )

abomination /le-20/ every developer should know floating point format, starts numbers - 1e-1 same 0.1, 5e-3 same 0.005. le-20 l not floating point number.
d.processraw(s, nbytes/2, false, false); d.setkws("abomination", ); this code should not compile. also, should not set search during processing.
i'm not clear on use of -kws vs -keyphrase vx -kws-threshold. using -kws mean don't need other 2 since sets both phrase , threshold?
yes, keyword list replaces command line option
am assuming wrong kws doesn't return hyp? t
it not return hypothesis because not pass proper audio decoder. need
bb.order(byteorder.little_endian);` without it passes big-endian data (java default). swig example in sources has that.

cmn range of 70 indicates endian problems. proper endian first cmn value should 30 60.
