TextToSpeech Example

A TextToSpeech instance can only be used to synthesize text once it has completed its initialization. Implement the TextToSpeech.OnInitListener to be notified of the completion of the initialization.

When you are done using the TextToSpeech instance, call the shutdown() method to release the native resources used by the TextToSpeech engine.

Example:

Code:

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <EditText

        android:id="@+id/editText1"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_marginLeft="10dp"

        android:layout_marginRight="10dp"

        android:layout_marginTop="20dp"

        android:ems="10" >

        <requestFocus />

    </EditText>

    <ImageView

        android:id="@+id/imageView1"

        android:layout_width="58dp"

        android:layout_height="72dp"

        android:layout_gravity="right"

        android:layout_marginRight="50dp"

        android:layout_marginTop="30dp"

        android:src="@drawable/audio_speak" />

</LinearLayout>

Changing Language

You can change language to speak by using setLanguage() function. Lot of languages are supported like Canada, French, Chinese, Germany etc.,

tts.setLanguage(Locale.CHINESE); // Chinese language 



Changing Pitch Rate

You can set speed pitch level by using setPitch() function. By default the value is 1.0 You can set lower values than 1.0 to decrease pitch level or greater values for increase pitch level.

tts.setPitch(0.6);



Changing Speed Rate

The speed rate can be set using setSpeechRate(). This also will take default of 1.0 value. You can double the speed rate by setting 2.0 or make half the speed level by setting 0.5

tts.setSpeechRate(2);
