Keyphrase Search

[Yakiv]

Hello. I'm using pocketsphinx on Android for search keyphrase "okay house":

ar = edu.cmu.pocketsphinx.SpeechRecognizerSetup.defaultSetup()
             .setAcousticModel(new File(modelsDir, "hmm"))
             .setDictionary(new File(modelsDir, "dict/cmu07a.dic"))
             .setKeywordThreshold(1e-40f)
             .setBoolean("-allphone_ci", true)
             .getRecognizer();
ar.addListener(new ActivationListener());

ar.addKeyphraseSearch(KWS_SEARCH, "okay house");

But I get too much false positive matches. What I am doing wrong or, maybe, any tricks and tips?

you can play with this value

.setKeywordThreshold(1e-40f)

to get right balance between false alarms and misses. You can try values like 1e-20, 1e-5, 1e-1.
