Now to open this dialog, you need to add the below code to your any of the button’s click listener.

int REQUEST_CODE = 1;
String DIALOG_TEXT = "Speech recognition demo";
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, DIALOG_TEXT);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
                   RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, REQUEST_CODE);

String resultSpeech = "";
@Override
protected void onActivityResult(int requestCode, int resultcode, Intent intent) {
    super.onActivityResult(requestCode, resultcode, intent);
    ArrayList<String> speech;
    if (resultcode == RESULT_OK) {  
        if (requestCode == REQUEST_CODE) {
            speech = intent.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            resultSpeech = speech.get(0);
            //you can set resultSpeech to your EditText or TextView
        }
    }
}
