How to see if word exists in Pocketsphinx dictionary?

Question

I simply want to see if a string exists in a dictionary file. (Dictionary file at bottom of question)

I want to check if the voice recognizer can recognize a word or not. For example, the recognizer will not be able to recognize a string of ahdfojakdlfafiop, because that is not defined in the dictionary. So, can I check if a word is in the dictionary of pocktsphinx?

Something like:

    if(myString.existsInDictionary){
startListeningBecauseExists();
    }else(
//Doesn't exist in dictionary!!!
       }

I just want a way to be able to tell if the recognizer can listen for what I want it to listen to.

here is the dictionary file:

Thanks,

In C there is ps_lookup_word function which allows you to lookup for the word:

if (ps_lookup_word(ps, "abc") == NULL) {
    // do something
}

In Java wrapper it's a method Decoder.lookupWord:

if(decoder.lookupWord("abc") == null) {
    // do something
}

In Android, you can access decoder from Recognizer:

if(recognizer.getDecoder().lookupWord("abc") == null) {
    // do something
}
