Voice recognition Android and Java

This is the base code you can use to implement a voice recognition app for android using java.


 private void startVoiceRecognition()
    {
   
    final String TAG="teste3";
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                "com.domain.app");

        SpeechRecognizer recognizer = SpeechRecognizer
                .createSpeechRecognizer(this.getApplicationContext());
        RecognitionListener listener = new RecognitionListener() {
            @Override
            public void onResults(Bundle results) {
                ArrayList<String> voiceResults = results
                        .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
               
                       
                           
                if (voiceResults == null) {
                    Log.e(TAG, "No voice results");
                } else {
                    Log.d(TAG, "Printing matches: ");
                    for (String match : voiceResults) {
                        Log.d(TAG, match);
                     
            }
}


Remember to add the correct permissions in your AndroidManifest.xml. If you don't you will get several errors. You need to be connected to internet to use voice recognizer.
