Android TextToSpeech Example
Let's write the code to convert text into voice.
activity_main.xml
Drag one textview, one edittext and one button for the layout. Now the activity_main.xml file will look like this:
File: activity_main.xml
- <RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- tools:context=".MainActivity" >
- <EditText
- android:id="@+id/editText1"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignParentLeft="true"
- android:layout_alignParentTop="true"
- android:layout_marginLeft="77dp"
- android:layout_marginTop="42dp"
- android:ems="10" >
- <requestFocus />
- </EditText>
- <Button
- android:id="@+id/button1"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignLeft="@+id/editText1"
- android:layout_below="@+id/editText1"
- android:layout_marginLeft="59dp"
- android:layout_marginTop="39dp"
- android:text="Speak" />
- <TextView
- android:id="@+id/textView1"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignBaseline="@+id/editText1"
- android:layout_alignBottom="@+id/editText1"
- android:layout_alignParentLeft="true"
- android:text="Enter Text:" />
- </RelativeLayout>
Activity class
Let's see the code to speak the given text.
File: MainActivity.java
- package com.example.texttospeech;
- import android.os.Bundle;
- import android.app.Activity;
- import android.view.Menu;
- 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.EditText;
- public class MainActivity extends Activity implements
- TextToSpeech.OnInitListener {
- /** Called when the activity is first created. */
- private TextToSpeech tts;
- private Button buttonSpeak;
- private EditText editText;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_main);
- tts = new TextToSpeech(this, this);
- buttonSpeak = (Button) findViewById(R.id.button1);
- editText = (EditText) findViewById(R.id.editText1);
- buttonSpeak.setOnClickListener(new View.OnClickListener() {
- @Override
- public void onClick(View arg0) {
- speakOut();
- }
- });
- }
- @Override
- public void onDestroy() {
- // Don't forget to shutdown tts!
- if (tts != null) {
- tts.stop();
- tts.shutdown();
- }
- super.onDestroy();
- }
- @Override
- public void onInit(int status) {
- 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 {
- buttonSpeak.setEnabled(true);
- speakOut();
- }
- } else {
- Log.e("TTS", "Initilization Failed!");
- }
- }
- private void speakOut() {
- String text = editText.getText().toString();
- tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
- }
- @Override
- public boolean onCreateOptionsMenu(Menu menu) {
- // Inflate the menu; this adds items to the action bar if it is present.
- getMenuInflater().inflate(R.menu.activity_main, menu);
- return true;
- }
- }
