| Text to Speech with Language Changer Option |
In this post we are going to make a Android Application using the text to speech feature. What differs this tutorial with the other is this tutorial uses a language changing option. So the text can be spoken in different accent based on the country selected.
This is the source code for main source in java:
package org.agung.text2speech;
import java.util.Locale;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainSpeak extends Activity implements OnInitListener {
String m_strInputText;
EditText m_edtInputText;
Button m_btnSpeak;
Toast m_toast;
private TextToSpeech m_TTS;
private int MY_CHECK_DATA = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_speak);
m_edtInputText = (EditText)findViewById(R.id.edtInputText);
m_btnSpeak = (Button)findViewById(R.id.btnSpeak);
Intent m_checkTTSIntent = new Intent();
m_checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(m_checkTTSIntent, MY_CHECK_DATA);
m_btnSpeak.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View argView) {
// TODO Auto-generated method stub
m_strInputText = m_edtInputText.getText().toString();
speakText(m_strInputText);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == MY_CHECK_DATA){
if(resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS){
m_TTS = new TextToSpeech(this,this);
}
else
{
Intent m_installTTSIntent = new Intent();
m_installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(m_installTTSIntent);
}
}
}
private void speakText(String text){
m_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_speak, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.langEnglish:
m_TTS.setLanguage(Locale.US);
m_toast = Toast.makeText(MainSpeak.this, "English", Toast.LENGTH_SHORT);
m_toast.setGravity(Gravity.CENTER, 0, 0);
m_toast.show();
return true;
case R.id.langGerman:
m_TTS.setLanguage(Locale.GERMAN);
m_toast = Toast.makeText(MainSpeak.this, "German", Toast.LENGTH_SHORT);
m_toast.setGravity(Gravity.CENTER, 0, 0);
m_toast.show();
return true;
case R.id.langFrench:
m_TTS.setLanguage(Locale.FRENCH);
m_toast = Toast.makeText(MainSpeak.this, "French", Toast.LENGTH_SHORT);
m_toast.setGravity(Gravity.CENTER, 0, 0);
m_toast.show();
return true;
case R.id.langItalian:
m_TTS.setLanguage(Locale.ITALIAN);
m_toast = Toast.makeText(MainSpeak.this, "Italian", Toast.LENGTH_SHORT);
m_toast.setGravity(Gravity.CENTER, 0, 0);
m_toast.show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public void onInit(int status) {
// TODO Auto-generated method stub
if(status == TextToSpeech.SUCCESS)
{
m_TTS.setLanguage(Locale.US);
Log.e("TTS INIT", "TTS SUCCESS");
}
else if(status == TextToSpeech.ERROR)
{
Log.e("TTS INIT", "TTS ERROR");
}
}
}
This is the layout xml source code:
<RelativeLayout xmlns:android="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=".MainSpeak" >
<TextView
android:id="@+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:gravity="center"
android:text="Text to Speech Test"
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="@+id/edtInputText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="@+id/tvTitle"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="@+id/btnSpeak"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/edtInputText"
android:layout_centerHorizontal="true"
android:text="Speak" />
</RelativeLayout>
This is the xml source code for the menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@+id/chooseLang" android:title="@string/choose_lang">
<menu>
<item android:id="@+id/langEnglish" android:title="@string/lang_en" android:icon="@drawable/us"/>
<item android:id="@+id/langGerman" android:title="@string/lang_de" android:icon="@drawable/de"/>
<item android:id="@+id/langFrench" android:title="@string/lang_fr" android:icon="@drawable/fr"/>
<item android:id="@+id/langItalian" android:title="@string/lang_it" android:icon="@drawable/it"/>
</menu>
</item>
</menu>
