Android Text to Speech | Tutorial Android

Kali ini saya mau berbagi contoh aplikasi sederhana Text to Speech pada Android. Aplikasinya sederhana saja, jadi nanti aplikasinya mengeluarkan suara dari Text yang kita inputkan. Mau tau gimana cara membuatnya? Cekidott....

1. Buat project baru dengan nama "TextToSpeech" dengan nama activity "AndroidTextToSpeechActivity" dan layoutnya "main".

2. Masukkan kodingan berikut pada AndroidTextToSpeechActivity.java

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.EditText;
import android.widget.ImageButton;

public class AndroidTextToSpeechActivity extends Activity implements
       TextToSpeech.OnInitListener {
   /** Called when the activity is first created. */

   private TextToSpeech tts;
   private ImageButton btnSpeak;
   private EditText txtText;

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       tts = new TextToSpeech(this, this);

       btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

       txtText = (EditText) findViewById(R.id.txtText);

       // button on click event
       btnSpeak.setOnClickListener(new View.OnClickListener() {

           public void onClick(View arg0) {
               speakOut();
           }

       });
   }

   @Override
   public void onDestroy() {
       // Don't forget to shutdown!
       if (tts != null) {
           tts.stop();
           tts.shutdown();
       }
       super.onDestroy();
   }

   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 {
               btnSpeak.setEnabled(true);
               speakOut();
           }

       } else {
           Log.e("TTS", "Initilization Failed");
       }

   }

   private void speakOut() {

       String text = txtText.getText().toString();

       tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
   }
}

3. Selanjutnya pada main.xml, masukkan ....

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="#ffffff">

    <TextView android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="Text To Speech"
                android:padding="15dip"
                android:textColor="#000000"
                android:textSize="26dip"
                android:gravity="center"
                android:textStyle="bold"/>

    <EditText android:id="@+id/txtText"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="Enter some text to speak"
        android:layout_marginTop="20dip"
        android:layout_margin="10dip"/>

    <ImageButton
        android:id="@+id/btnSpeak"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/speak" />

</LinearLayout>
