Un minimaliste exemple pour tester rapidement la TTS système:

private TextToSpeech textToSpeechSystem;
@Override
protected void onStart() {
super.onStart();
textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
String textToSay = "Hello world, this is a test message!";
textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
}
}
});
}

Si vous n'utilisez pas de messages localisés textToSpeechSystem.setLanguage(..) est important, car vos utilisateurs ne sont pas tous des anglais comme leur langue par défaut de sorte que la prononciation des mots sera mauvais. Mais pour les tests TTS en général, cet extrait est assez
