java - CMUSphinx never recognizes any word from audio files -


sphinx doesn't seem recognize or process audio files accepts audio stream spits out empty array(speechresult result). feel there isn't issues audio file i'm using because i've tried several , doesn't work on of them. have audio file know works? , there stands out causing stream not produce transcription?

public static void main(string args[]) throws ioexception {     configuration configuration = new configuration();     configuration.setacousticmodelpath("resource:/edu/cmu/sphinx/models/en-us/en-us");     configuration.setdictionarypath("resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");     configuration.setlanguagemodelpath("resource:/edu/cmu/sphinx/models/en-us/en-us.lm.dmp");      streamspeechrecognizer recognizer = new streamspeechrecognizer(configuration);     //recognizer.startrecognition(new fileinputstream("e:/1video/hello-5.mp3"));      file file = new file("e:/1video/bargain_not.wav");     fileinputstream fis = new fileinputstream(file);     inputstream = new fileinputstream(file);      //is = automaticspeechrecognition.class.getresourceasstream("/edu/cmu/sphinx/demo/aligner/10001-90210-01803.wav");     recognizer.startrecognition(is);     speechresult result = null;     while((result = recognizer.getresult()) != null) {         system.out.println(result.getresult());          system.out.println(result.gethypothesis());          system.out.println(result.getwords());      }     //result = recognizer.getresult();     //system.out.println(result);     //system.out.println(result.tostring());     //system.out.println(result.getwords());     /*for (wordresult wordresult : result.getwords())     {         system.out.println(wordresult);     }*/     recognizer.stoprecognition();   }

here's output running -- doesn't seem have failures
