Title Body

My android application has text to speak feature and more then one activity uses this feature. So created a static helper class to made this easy. import java.util.Locale; import android.content.Context; import android.speech.tts.TextToSpeech; import android.speech.tts.TextToSpeech.OnInitListener; import android.util.Log; public class TextToSpeechController implements OnInitListener { private static final String TAG = "TextToSpeechController"; private TextToSpeech myTTS; private String textToSpeak; private Context context; private static TextToSpeechController singleton; public static TextToSpeechController getInstance(Context ctx) { if (singleton == null) singleton = new TextToSpeechController(ctx); return singleton; } private TextToSpeechController(Context ctx) { context = ctx; } public void speak(String text) { textToSpeak = text; if (myTTS == null) { // currently can't change Locale until speech ends try { // Initialize text-to-speech. This is an asynchronous operation. // The OnInitListener (second argument) is called after // initialization completes. myTTS = new TextToSpeech(context, this); } catch (Exception e) { e.printStackTrace(); } } sayText(); } public void onInit(int initStatus) { if (initStatus == TextToSpeech.SUCCESS) { if (myTTS.isLanguageAvailable(Locale.UK) == TextToSpeech.LANG_AVAILABLE) myTTS.setLanguage(Locale.UK); } // status can be either TextToSpeech.SUCCESS or TextToSpeech.ERROR. if (initStatus == TextToSpeech.SUCCESS) { int result = myTTS.setLanguage(Locale.UK); if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
