I'm trying to implement Text to Speech onto my app. I've followed the following guide but my app keeps crashing after the splash screen.
link: http://www.androidhive.info/2012/01/android-text-to-speech-tutorial/
Main Activity Class I have this
String alertMessage = AppResources.ALERT_MSG;
SpeakDemo speak = new SpeakDemo(null, alertMessage);
speak.speakOut();
If I remove the speak.speakOut(); line the app works fine.
App Resources is another class with the following message box
public static String ALERT_MSG = "Welcome!";
The SpeakDemo Class is:
import java.util.Locale;
import android.content.Context;
import android.speech.tts.TextToSpeech;
import android.util.Log;
public class SpeakDemo implements TextToSpeech.OnInitListener{
private TextToSpeech tts;
private Context context;
private String message;
public SpeakDemo(Context context, String message){
this.context = context;
this.message = message;
}
#Override
public void onInit(int status) {
// TODO Auto-generated method stub
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "This Language is not supported");
} else {
speakOut();
}
} else {
Log.e("TTS", "Initilization Failed!");
}
}
public void speakOut(){
tts.speak(message, TextToSpeech.QUEUE_FLUSH, null);
}
}
Any Ideas?
Thanks
You need to instantiate the TextToSpeech.
Change
public SpeakDemo(Context context, String message){
this.context = context;
this.message = message;
tts = new TextToSpeech(context, this);
}
//FOR TEXT TO SPEECH
#Override
public void onInit(int status) {
// TODO Auto-generated method stub
String msg=text.getText().toString();
if(status==TextToSpeech.SUCCESS)
{
tts.setLanguage(Locale.US);
tts.speak(msg,TextToSpeech.QUEUE_FLUSH,null);
}
else
Log.e("TTS","INITILIZATION FAILED");
}
public void onDestroy()
{
if (tts!=null)
{
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
Xml:
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Speak"
android:onClick="TTS"/>
Mainactivity:
TextToSpeech textToSpeech;
textToSpeech=new TextToSpeech(TTSpeech.this, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if(status==TextToSpeech.SUCCESS)
{
result=textToSpeech.setLanguage(Locale.ENGLISH);
}
else
{
Toast.makeText(TTSpeech.this, "speech not work", Toast.LENGTH_SHORT).show();
}
}
});
}
public void TTS(View view) {
switch (view.getId())
{
case R.id.button:
if(result== TextToSpeech.LANG_NOT_SUPPORTED || result==TextToSpeech.LANG_MISSING_DATA)
{
Toast.makeText(TTSpeech.this, "speech not nt work", Toast.LENGTH_SHORT).show();
}
else
{
text=ed.getText().toString();
textToSpeech.speak(text,TextToSpeech.QUEUE_FLUSH,null);
}
break;
}
if you get problem you can comment me.

I'm developing an application for workout with multiple activities that has text to speech for instructions.
My problem is that the text to speech takes too long to initialize even though i have it in a helper class and the instruction don't play when the activity starts, i thought maybe i should make a text to speech service, but i don't know how and i didn't find any tutorials.
private TextToSpeech mTts = null;
private boolean isLoaded = false;
public void init(Context context) {
try {
mTts = new TextToSpeech(context, onInitListener);
} catch (Exception e) {
e.printStackTrace();
}
}
private final TextToSpeech.OnInitListener onInitListener = new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
mTts.setLanguage(Locale.getDefault());
isLoaded = true;
}
}
};
public void initQueue(String text) {
if (isLoaded) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
mTts.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
} else {
mTts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
}
else
Log.e("error", "TTS Not Initialized");
}
How i can create a speech service and make it speak instructions from an activity?
I have a text to speech function in my android app that works to an onClick event, there is an issue when the activity starts, the text to speech starts without clicking the button, is there a line of code I can put in to stop this happening, thank you.
package com.androidhive.texttospeech;
import java.util.Locale;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class AndroidTextToSpeechActivity extends Activity implements
TextToSpeech.OnInitListener {
/** Called when the activity is first created. */
private TextToSpeech tts;
private Button button1;
private TextView txtText;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tts = new TextToSpeech(this, this);
button1 = (Button) findViewById(R.id.button1);
txtText = (TextView) findViewById(R.id.txtText);
// button on click event
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
speakOut();
}
});
}
#Override
public void onDestroy() {
// Don't forget to shutdown!
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
#Override
public void onInit(int status) {
// TODO Auto-generated method stub
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(Locale.US);
// tts.setPitch(5); // set pitch level
// tts.setSpeechRate(2); // set speech speed rate
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language is not supported");
} else {
button1.setEnabled(true);
speakOut();
}
} else {
Log.e("TTS", "Initilization Failed");
}
}
private void speakOut() {
String text = txtText.getText().toString();
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
}
The reason why this happens is because you invoke speakOut# In the onInit() method, remove speakOut():
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language is not supported");
} else {
button1.setEnabled(true);
// speakOut();
}
I saw these codes in onInit(), which will be called after the TextToSpeech is instantiated and initialized successfully. See the speakOut() here? That's what causes your problem.
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language is not supported");
} else {
button1.setEnabled(true);
speakOut();
}
I'm totally new to Android and I decided to create a Siri look-a-like app, which is working fine, I searched before asking but I can't get it to work: Android speech Recognition App Without Pop Up
So I want to hide the pop-up inside my Android app, but I really don't now how to do it properly. I'll be very glad if someone could help me doing this. I have already added the correct permissions in Android Manifest...

Step 1
In Android Manifest.xml, add the permission.
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Step 2
In the Layout screen, i am using a Toggle Button to start/stop voice listening.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
.......
<ToggleButton
android:id="#+id/toggleButton1"
android:layout_width="wrap_content"

android:layout_centerHorizontal="true"
android:layout_marginTop="26dp"
android:text="ToggleButton" />

I tried to do something extremely simple or I thought it was.
In my BluetoothChat, I set
public static boolean potato = false;
In the onCreateBundle of my MainActivity, I have
talker = new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener()
{
#Override
public void onInit(int status)
{
if(status != TextToSpeech.ERROR)
{
talker.setLanguage(Locale.US);
}
}
});
if(BluetoothChat.potato == false)
{
speakOut();
}
When speakOut(); is called by a button or separately by itself it works.
public void speakOut()
{
String original ="You will have a seizure in thirty seconds.";
talker.speak(original,TextToSpeech.QUEUE_FLUSH,null);
}
However, this does not work. Can someone explain why?
Thanks to the help from Payeli. Here is the solution! Place the if statement within the onInit.
talker = new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener()
{
#Override
public void onInit(int status)
{
if(status != TextToSpeech.ERROR)
{
talker.setLanguage(Locale.US);
}
if(BluetoothChat.potato == false)
{
speakOut();
}
}
});
I have looked around through the other questions with the same problem, but because this error is specific to everyone's personal code, they didn't help much. I'm getting the following error:

The Stack-trace tells me to go to this line:
thingsYouSaid.add(youJustSaid.get(0).toString());
However, after lots of trial and error I can't work out what's wrong with it. I tried adding .toString() just to see if it magically fixed something, but no.
Hopefully someone will be able to help me solve this :)
Merry Christmas!
I don't see anywhere that you are initializing thingsYouSaid;. You declare it like this
private ArrayList<String> thingsYouSaid;
but you don't initialize it. Try changing that to
private ArrayList<String> thingsYouSaid = new ArrayList<String>();
Edit
I haven't worked with TextToSpeech but I can tell you that you are comparing Strings incorrectly here
thingsYouSaid.get(numberOfThingsSaid) == "Hello" || thingsYouSaid.get(numberOfThingsSaid) == "Hi")
inside think(). You should use equals() to compare Strings.
if ((("Hello".equals(thingsYouSaid.get(numberOfThingsSaid))
|| ("Hi".equals(thingsYouSaid.get(numberOfThingsSaid))))
also, you should add break; statements at the end of each case or the logic will fall through even if it matches one of the first case statements.
thingsYouSaid is not instantiated anywhere in your code. You should instantiate it (you can do that while declaring):
ArrayList<String> thingsYouSaid = new ArrayList<String>();
