Answer 2

A minimalistic example to quickly test the TTS system:

private TextToSpeech textToSpeechSystem;

@Override
protected void onStart() {
  super.onStart();
  textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                String textToSay = "Hello world, this is a test message!";
                textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
            }
        }
   });
}

If you don't use localized messages textToSpeechSystem.setLanguage(..) is important as well, since your users probably don't all have English set as their default language so the pronunciation of the words will be wrong. But for testing TTS in general this snippet is enough

Answer 4

Text to speech is built into Android 1.6+. Here is a simple example of how to do it.

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

Here are instructions on how to download sample code from the Android SDK Manager:

1. Launch the Android SDK Manager.

   a. On Windows, double-click the SDK Manager.exe file at the root of the Android SDK directory.

   b. On Mac or Linux, open a terminal to the tools/ directory in the Android SDK, then execute android sdk.

2. Expand the list of packages for the latest Android platform.

3. Select and download Samples for SDK. When the download is complete, you can find the source code for all samples at this location:

/sdk/samples/android-version/

(i.e. \android-sdk-windows\samples\android-16\ApiDemos\src\com\example\android\apis\app\TextToSpeechActivity.java)

Answer 6

Try this, its simple : **speakout.xml : **

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#3498db"
android:weightSum="1"
android:orientation="vertical" >
<TextView
android:id="@+id/txtheader"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight=".1"
android:gravity="center"
android:padding="3dp"
android:text="Speak Out!!!"
android:textColor="#fff"
android:textSize="25sp"
android:textStyle="bold" />
<EditText
android:id="@+id/edtTexttoSpeak"
android:layout_width="match_parent"
android:layout_weight=".5"
android:background="#fff"
android:textColor="#2c3e50"
android:text="Hi there!!!"
android:padding="5dp"
android:gravity="top|left"
android:layout_height="0dp"/>
<Button
android:id="@+id/btnspeakout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=".1"
android:background="#e74c3c"
android:textColor="#fff"
android:text="SPEAK OUT"/>
</LinearLayout>

And Your SpeakOut.java :

import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class SpeakOut extends Activity implements OnInitListener {
private TextToSpeech repeatTTS;
Button btnspeakout;
EditText edtTexttoSpeak;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.speakout);
    btnspeakout = (Button) findViewById(R.id.btnspeakout);
    edtTexttoSpeak = (EditText) findViewById(R.id.edtTexttoSpeak);
    repeatTTS = new TextToSpeech(this, this);
    btnspeakout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            repeatTTS.speak(edtTexttoSpeak.getText().toString(),
            TextToSpeech.QUEUE_FLUSH, null);
        }
    });
}

@Override
    public void onInit(int arg0) {
        // TODO Auto-generated method stub
    }
}
