android – Error ERROR_RECOGNIZER_BUSY with offline speech recognition

Posted by: admin May 14, 2020 Leave a comment

Questions:

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.

public class VoiceRecognitionActivity extends Activity implements RecognitionListener {

    private TextView returnedText;
    private static ProgressBar progressBar;
    private static SpeechRecognizer speech = null;
    private static Intent recognizerIntent;
    private String LOG_TAG = "VoiceRecognitionActivity";
    private Button button1;
    Activity activity = VoiceRecognitionActivity.this;
    private TextView textView2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        returnedText = (TextView) findViewById(R.id.textView1);
        textView2 = (TextView) findViewById(R.id.textView2);
        progressBar = (ProgressBar) findViewById(R.id.progressBar1);
        button1 = (Button) findViewById(R.id.button1);

         getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    //  toggleButton = (ToggleButton) findViewById(R.id.toggleButton1);

         PackageManager pm = getPackageManager();
         List<ResolveInfo> activities = pm.queryIntentActivities( new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
         if (activities.size() != 0) 
         {
             createSpeechAgain(VoiceRecognitionActivity.this);
         } 
         else 
         {
             textView2.setText("Recognizer_not_present");
         }




        button1.setOnClickListener(new OnClickListener() {

How to&Answers:

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

Answer:

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.
