Android Text to Speech Example

In this tutorial we are going to implement text to speech in the android application. One of the special feature of android is speech accessibility to speak different language.

User needs to enter a text and press the button to hear it.

File : res/layout/activity_text_to_speech.xml

<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=".Text_to_speechActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="16dp"
        android:text="Enter the text to speech"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="26dp"
        android:ems="12" />

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_below="@+id/editText1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="67dp"
        android:src="@drawable/speak" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/imageButton1"
        android:layout_centerHorizontal="true"
        android:text="Speak"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textStyle="bold" />


</RelativeLayout>

@Override

setContentView(R.layout.activity_text_to_speech);

speech = new TextToSpeech(this, this);
speak = (ImageButton) findViewById(R.id.imageButton1);
comment = (EditText) findViewById(R.id.editText1);

// button on click event
speak.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
speak();
}
});
}

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

@Override
public void onInit(int status)
{
if (status == TextToSpeech.SUCCESS)
{
int result = speech.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "This Language is not supported");
}
else
{
speak.setEnabled(true);
speak();
}
}

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

private void speak() {
String text = comment.getText().toString();
speech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
}


Note : import android.speech.tts.TextToSpeech is used for speak capability
