In this tutorial we shall show you how to use the TextToSpeech class to convert Text-to-Speech in Android. The idea is straightforward. We want to type text in an text area and then press button to transform it to speech. You can actually listen to it when you launch the built in application of Android.
So the basic steps you have to take in order to convert Text to Speech in Anroid you have to:
- Create an Activity that extends
OnInitListner - Specify and create a
TextToSpeechinstance - Create an
EditTextcomponent for the User to type his text - Create a
Buttonthat when clicked the text is converted to speech and played through the speakers - Create a new
Intentand usesetActionto set up the intent with the TextToSpeech engine
package com.javacodegeeks.android.tts;
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 TtsActivity extends Activity implements OnInitListener {
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(TtsActivity.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(TtsActivity.this,
"Text-To-Speech engine is initialized", Toast.LENGTH_LONG).show();
}
else if (status == TextToSpeech.ERROR) {
Toast.makeText(TtsActivity.this,
"Error occurred while initializing Text-To-Speech engine", Toast.LENGTH_LONG).show();
}
}
}
