How To Use Android’s Text To Speech Capabilities

Last topic published on this forum was How to send an Email.

Underlying Algorithm:

Basic description of algorithm in step by step form:
1.) Create a Project MyTextToSpeech.
2.) Put the following code snippet in res/layout/main.xml:

<!--?xml version="1.0" encoding="utf-8"?-->
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

android:text=""
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

<button> android:text="Speak to me"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

3.) You just need to import the following packages and create a TextToSpeech object.

import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;

4.) The second is an OnInitListener which you will need to implement.
5.) Run the Application.

Steps to Create:

1.) Open Eclipse. Use the New Project Wizard and select Android Project Give the respective project name i.e. MyTextToSpeech. Enter following information:
Project name: MyTextToSpeech
Build Target: Android APIs 2.1
Application name: MyTextToSpeech
Package name: com.app.MyTextToSpeech
Create Activity: MyTextToSpeech

On Clicking Finish MyTextToSpeech code structure is generated with the necessary Android Packages being imported along with MyTextToSpeech.java. MyTextToSpeech class will look like following:

package com.app.MyTextToSpeech;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MyTextToSpeech extends Activity implements OnInitListener{
/** Called when the activity is first created. */
private int MY_DATA_CHECK_CODE = 0;

private TextToSpeech tts;

private EditText inputText;
private Button speakButton;

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

inputText = (EditText) findViewById(R.id.input_text);
speakButton = (Button) findViewById(R.id.speak_button);

speakButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String text = inputText.getText().toString();
if (text!=null && text.length()>0) {
Toast.makeText(MyTextToSpeech.this, "Saying: " + text, Toast.LENGTH_LONG).show();
tts.speak(text, TextToSpeech.QUEUE_ADD, null);
}
}
});
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
tts = new TextToSpeech(this, this);
}
else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}

@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
Toast.makeText(MyTextToSpeech.this, "Text-To-Speech engine is initialized", Toast.LENGTH_LONG).show();
}
else if (status == TextToSpeech.ERROR) {
Toast.makeText(MyTextToSpeech.this, "Error occurred while initializing Text-To-Speech engine", Toast.LENGTH_LONG).show();
}
}
}

Output –The final output:
