Android voice recognition dont speak

I'm making an app where I ask a question and the answering machine answers me depending on the question, but the problem is that the cell phone listens but it does not respond, that is, it does not talk.
She is speak in open app with welcome, but after no talk

Trying to implement a speech to text, don't know what is wrong

New to Android development, trying to implement a speech to text that will print the words on the screen in real time but getting the below error. Can't seem to understand where the problem is. Is it because I am calling the startRecording() and stopRecording() from the togglebutton events or is is it something else entirely.
com.example.android.moviebud E/SpeechRecognizer: not connected to the recognition service

Trying to use SpeechRecognizer (Android speech recognition) but it's not starting?

Here's my code:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_route);
SetupButton();
}
private void SetupButton()
{
Button createNewMessage = (Button) findViewById(R.id.button);
createNewMessage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ListenForNewMessage();
}
});
}
private void ListenForNewMessage()
{
final SpeechRecognizer newDeliverySpeech = SpeechRecognizer.createSpeechRecognizer(this);
RecognitionListener newDeliveryRecognitionListener = new RecognitionListener() {
#Override
public void onReadyForSpeech(Bundle params) {
Log.d("SpeechListening","onReadyForSpeech");
}
#Override
public void onBeginningOfSpeech() {
Log.d("SpeechListening","onBeginningOfSpeech");
}
#Override
public void onRmsChanged(float rmsdB) {
//do nothing
}
#Override
public void onBufferReceived(byte[] buffer) {
//do nothing
}
#Override
public void onEndOfSpeech() {
Log.d("SpeechListening","onEndOfSpeech");
}
#Override
public void onError(int error) {
//do nothing
}
#Override
public void onResults(Bundle results) {
ArrayList<String> userMessage;
userMessage = results.getStringArrayList(RESULTS_RECOGNITION);
PushNewDelivery(userMessage);
}
#Override
public void onPartialResults(Bundle partialResults) {
//do nothing
}
#Override
public void onEvent(int eventType, Bundle params) {
//do nothing
}
};
newDeliverySpeech.setRecognitionListener(newDeliveryRecognitionListener);
if (newDeliverySpeech.isRecognitionAvailable(getApplicationContext()))
{
Log.d("SpeechListening","started listening hopefully");
newDeliverySpeech.startListening(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH));
}
}
}
The problem is, only the started listening hopefully is logged, the RecognitionListener never has onReadyForSpeech() or any of its methods called.
Can someone please tell me what I'm doing wrong here?

You can change this below line
newDeliverySpeech.startListening(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH));
To,
Intent mSpeechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "voice.recognition.test");
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
newDeliverySpeech.startListening(mSpeechIntent);

Ask the user for the permission to record audio before calling startListening:
String[] permissions = {Manifest.permission.RECORD_AUDIO};
ActivityCompat.requestPermissions(this, permissions, REQUEST_RECORD_AUDIO_PERMISSION);
https://developer.android.com/guide/topics/media/mediarecorder#audio-record-permission

onReadyForSpeech() in Android speech recognition (SpeechRecognizer) never gets called

Here's my code:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_route);
SetupButton();
}
private void SetupButton()
{
Button createNewMessage = (Button) findViewById(R.id.button);
createNewMessage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ListenForNewMessage();
}
});
}
private void ListenForNewMessage()
{
final SpeechRecognizer newDeliverySpeech = SpeechRecognizer.createSpeechRecognizer(this);
RecognitionListener newDeliveryRecognitionListener = new RecognitionListener() {
#Override
public void onReadyForSpeech(Bundle params) {
Log.d("SpeechListening","onReadyForSpeech");
}
#Override
public void onBeginningOfSpeech() {
Log.d("SpeechListening","onBeginningOfSpeech");

}
#Override

Log.d("SpeechListening","onEndOfSpeech");
}
#Override
public void onError(int error) {
//do nothing
}
#Override
public void onResults(Bundle results) {
ArrayList<String> userMessage;
userMessage = results.getStringArrayList(RESULTS_RECOGNITION);
PushNewDelivery(userMessage);
}
#Override
public void onPartialResults(Bundle partialResults) {
//do nothing
}
#Override

};
newDeliverySpeech.setRecognitionListener(newDeliveryRecognitionListener);
if (newDeliverySpeech.isRecognitionAvailable(getApplicationContext()))
{
Log.d("SpeechListening","started listening hopefully");
newDeliverySpeech.startListening(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH));
}
}
}

You are basically creating a new SpeechRecognizer object and register a new listener each time you click on the button. On top of that you create the SpeechRecognizer using the current Activity Context but you are actually using the Application context when calling: isRecognitionAvailable();
Try to create the SpeechRecognizer as a member object and register your listener when onCreate() is called. Also try to avoid using the Application context to avoid memory leaks.
Here is an example of how you should do it.
private SpeechRecognizer mDeliverySpeech;
private Intent mSpeechIntent;
private boolean mListening = false;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_route);
SetupButton();
SetupSpeechRecognizer();
mSpeechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, this.getPackageName());
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3);
}
private void SetupButton()
{
Button createNewMessage = (Button) findViewById(R.id.button);
createNewMessage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ListenForNewMessage();
}
});
}
private void SetupSpeechRecognizer()
{
mDeliverySpeech = SpeechRecognizer.createSpeechRecognizer(this);
RecognitionListener newDeliveryRecognitionListener = new RecognitionListener() {
#Override
public void onReadyForSpeech(Bundle params) {
Log.d("SpeechListening","onReadyForSpeech");
}
#Override
public void onBeginningOfSpeech() {
Log.d("SpeechListening","onBeginningOfSpeech");
}
#Override
public void onRmsChanged(float rmsdB) {
//do nothing
}
#Override
public void onBufferReceived(byte[] buffer) {
//do nothing
}
#Override
public void onEndOfSpeech() {
Log.d("SpeechListening","onEndOfSpeech");
}
#Override
public void onError(int error) {
//do nothing
}
#Override
public void onResults(Bundle results) {
ArrayList<String> userMessage;
userMessage = results.getStringArrayList(RESULTS_RECOGNITION);
PushNewDelivery(userMessage);
}
#Override
public void onPartialResults(Bundle partialResults) {
//do nothing
}
#Override
public void onEvent(int eventType, Bundle params) {
//do nothing
}
};
mDeliverySpeech.setRecognitionListener(newDeliveryRecognitionListener);
}
private void ListenForNewMessage()
{
if (mDeliverySpeech.isRecognitionAvailable(this) && !mListening)
{
Log.d("SpeechListening","started listening hopefully");
mListening = true;
mDeliverySpeech.startListening(mSpeechIntent);
new CountDownTimer(5000, 5000) {
public void onTick(long millisUntilFinished) {}
public void onFinish() {
mDeliverySpeech.stopListening();
mListening = false;
}
}.start();
}
}
Do not forget to properly handle the activity life cycle when working with listener to avoid memory leak.

How do I use Android SpeechRecognizer as a service?

I am trying to run Android voice recognition as a service. I can verify that the onCreate() and onStart() methods of the service are called, but no callbacks to the speech recognition methods are called, despite the fact that I have set up the SpeechRecognizer object correctly. The speech recognition seems to work when it is done in an activity instead of a service. How do I make it work as a service? Is this a manifest issue?

There are 2 things that I think you need to clarify and may provide you as a workaround.
Have declared the service in the manifest properly?
I believe this is something already addressed.
Speech recognition may not start "onCreate" of the service. I had done similar implementation but it didn't work. You can try placing the startListening(intent) in some other method and call it explicitly. This worked for me.
Let me know if it helps.
