Il motore di TTS di default su Android e' Pico e non sempre ci sono tutti i linguaggi installati ..quindi se si vuole che il telefono parli in inglese non ci sono problemi ma se si vuole una lingua un po' piu' esotica va scaricata a parte
Gli esempi su come usare Pico sono gia' inclusi negli esempi dei developer di Android quindi non c'e' molto da fare se non usare il sistema
La voce e' piuttosto metallica e robotica rispetto ad altri motori TTS ma c'e' da dire che i file sono estremamente compatti
un primo metodo per testare TTS e' il seguente ma di fatto non e' utile in casi reali di programmazione

package com.example.tts;
import android.os.Bundle;
import android.app.Activity;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
public class MainActivity extends Activity implements OnInitListener{
private TextToSpeech talker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
talker = new TextToSpeech(this, this);
say("Luca Innocenti");
}
public void say(String text2say){
talker.speak(text2say, TextToSpeech.QUEUE_FLUSH, null);
}
public void onInit(int status) {
//say("Luca Innocenti");
}
@Override
public void onDestroy() {
if (talker != null) {
talker.stop();
talker.shutdown();
}
super.onDestroy();
}
