Synthèse vocale (TTS) -Android

Je suis nouveau sur la plate-forme Android. Maintenant, je travaille sur TTS(Text to Speech). Si j'entre le texte dans un TextArea et que je souhaite qu'il soit converti en discours lorsque je cliquez sur le bouton Parler.

Quelqu'un peut m'aider?

La synthèse vocale est intégrée à Android 1.6+. Voici un exemple simple de la façon de le faire.

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

Voici les instructions sur la façon de télécharger un exemple de code à partir du Android SDK Manager:

  1. Lancez le Android SDK Manager.

    une. Sous Windows, double-cliquez sur le fichier SDK Manager.exe à la racine du répertoire Android SDK.

    b. Sur Mac ou Linux, ouvrez un terminal dans le répertoire tools/dans le SDK Android, puis exécutez Android sdk.

  2. Développez la liste des packages pour la dernière plate-forme Android.

  3. Sélectionnez et téléchargez des exemples pour SDK. Une fois le téléchargement terminé, vous pouvez trouver le code source de tous les exemples à cet emplacement:

Un exemple minimaliste pour tester rapidement le système TTS:

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 également important, car vos utilisateurs n'ont probablement pas tous l'anglais comme langue par défaut, la prononciation des mots sera donc incorrecte. Mais pour tester TTS en général, cet extrait est suffisant
