问题
I have made research on google offline speech recognition. but it works fine in google nexus 5(OS:-4.4) but same build if I implement in Samsung galaxy s5(OS:-5.0) it is not recognizing and it is showing this error:
8- ERROR_RECOGNIZER_BUSY.
Below is my code. By keeping this link as reference I have made a changes http://www.truiton.com/2014/06/android-speech-recognition-without-dialog-custom-activity/
Without internet voice must recognize. I have worked on Pocket sphinx but it take lot of side voice so client have rejected it.

回答1:
ERROR_RECOGNIZER_BUSY is often thrown when you didn't close the SpeechRecognizer proprely. Yo probably are already using one instance of the SpeechRecognizer.
See this http://developer.android.com/reference/android/speech/SpeechRecognizer.html
回答2:
ERROR_RECOGNIZER_BUSY get thrown when you start your speech recognizer again when its already running. As in your code
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
message = "RecognitionService busy";
Log.v("LOG_TAG", message);
speech.stopListening();
speech.destroy();
createSpeechAgain(VoiceRecognitionActivity.this);
break;
Simply edit your above code with
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
break;
As there is no need to start it again it is already running. If you will start recognition again it will keep throwing same error. and it will go in loop.
