Question

I’m making an app in which I ask a question and the phone answers me as the question asked,but the problem is that the phone listens but does not answer me, IE, does not speak.

public class MainActivity extends AppCompatActivity {

    private TextToSpeech myTTS;
    private SpeechRecognizer mySpeechReconizer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        Button mic = (Button) findViewById(R.id.mic);
        mic.setOnClickListener((view) ->
        {

                Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
                i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                        RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
                i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
                mySpeechReconizer.startListening(i);


        });

        initializeTextToSpeech();
        initializeSpeechReconizer();
    }

    private void initializeSpeechReconizer() {
        if (SpeechRecognizer.isRecognitionAvailable(this)) {
            mySpeechReconizer = SpeechRecognizer.createSpeechRecognizer(this);
            mySpeechReconizer.setRecognitionListener(new RecognitionListener() {
                @Override
                public void onReadyForSpeech(Bundle params) {

                }

                @Override

                }
