but the Julius output gives as -

Queries:

1. Is my X.grammar and X.voca perfectly fine?

2. How to make sure that the audio format matches the acoustic model format?

3. I have 15 audio files (X1.wav - X15.wav), why in every julius output I have same pass1_best as "<s> HOW GOTTEN PERFECTLY WHEN RECORDS BECAUSE MUCH"?

 

I am willing to share the datas when asked.  Please help.

Thanks ..!!

The problem is that in your grammar you are forcing the recognizer to recognizer a sequence as a sentence:

CONVERSATION: ACTION ADJECTIVE ADVERB AFFIRMATIVE COMMON CONJUNCTION DETERMINER EXCLAMATION INDEFINITE INFINITIVE INTERJECTION MODAL MONTH NEGATIVES NOUN 

Means that in a sentence first goes ACTION then ADJECTIVE then ADVERB then everything else. If you want alternatives you need to do something like 

CONVERSATION: ACTION

CONVERSATION: ADJECTIVE

and so on.

You can read documentation http://julius.sourceforge.jp/en_index.php?q=en_grammar.html to understand grammars in more details.
