Android SDK bring out a cool feature (from Android 1.6) called Text to Speech (TTS) which speaks the given text in different languages. Now I explore how they manage this to us.
What I do here? How to work with android text to speech or android speech synthesis. Also explained changing the language type, pitch level and speed level.Step 1: Create a new project by going to File ⇒ New Android Project and fill required details.
Step 2: Create a TextToSpeechActivity which extends Activity & add this activity in manifestfile.
Step 3: Now add following code to your TextToSpeechActivity class.
public class TextToSpeechActivity extends Activity {
private Button speakButton;
private EditText txtWriteText;
private TextToSpeech tts;
private Context context = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_text_to_speech);
speakButton = (Button) findViewById(R.id.speakButton);
txtWriteText = (EditText) findViewById(R.id.editTextWritenlisten);
// initialize the object with listener
try {
tts = new TextToSpeech(context, new OnInitListener() {
@Override
public void onInit(int status) {
// check initialization on tts & set language
if (status != TextToSpeech.ERROR) {
// can set different language
tts.setLanguage(Locale.US);
}
}
});
speakButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String text = txtWriteText.getText().toString();
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onDestroy() {
// Don't forget to shutdown tts!
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
}
Step 4: Now you can run the application, put some text in EditText field & click the button to listen. :)
More: You can also change Language, Pitch Rate & Speed Rate By following methods.
Change language:
tts.setLanguage(Locale.GERMAN); // german language
Change Pitch Rate:
tts.setPitch(.7f);
Change Speed Rate:
tts.setSpeechRate(2);
