Implementation steps:

1. Inheriting Texttospeech.oninitlistener

2. Implement the OnInit method here to load the language int result = Mtts.setlanguage (locale.us);

3. Initialize the instance Texttospeech mTts = MTts = new Texttospeech (This,
This//Texttospeech.oninitlistener
);

4. Call its Speak method private void SayHello () {
Select a random hello.
int hellolength = Hellos.length;
String Hello = Hellos[random.nextint (hellolength)];
Mtts.speak (Hello,
Texttospeech.queue_flush,//Drop all pending entries in the playback QUEUE.
NULL);
