android語音朗讀功能demo實現

                                           簡單的文本語音朗讀功能實現

實現這個功能主要用一個類，是TextToSpeech，廢話不都少，直接上代碼。總的來說效果一般，短語的停頓節奏不是很好。

介面很簡單，一個Button ,一個EditView,就不貼代碼了

public class ActivityResumptionArticle extends BaseActivity{

   private TextToSpeech mSpeech = null;
   private Button btn = null;

  private EditTextView ev = null;

 

protected void onCreate(Bundle arg0) {
  super.onCreate(arg0);

   setContentView(R.layout.activity_resumption_article);

//測試朗讀功能
  btn = (Button) findViewById(R.id.but);

  ev = (EditView)findViewById(R.id.ev);
  mSpeech = new TextToSpeech(this, new OnInitListener() {
   @Override
   public void onInit(int status) {
     if (status == TextToSpeech.SUCCESS) {

                    //下面這句代碼是主要的，設定語言，如果是英文的話，就用Locale.ENGLISH
                     int result = mSpeech.setLanguage(Locale.CHINA);
                     if (result == TextToSpeech.LANG_MISSING_DATA
                             || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                         Log.e("lanageTag", "not use");
                     } else {
                         btn.setEnabled(true);
                         mSpeech.speak("i love you", TextToSpeech.QUEUE_FLUSH,
                                 null);
                     }
                 }

   }
  });

//進度監聽器，有點粗糙，但夠用了，記得在done後將mpeech shutdown
  mSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() {
   @Override
   public void onStart(String utteranceId) {
   }
   
   @Override
   public void onError(String utteranceId) {
    
   }
   
   @Override
   public void onDone(String utteranceId) {
    mSpeech.shutdown();
   }
  });
   btn.setOnClickListener(new OnClickListener() {

             @Override
             public void onClick(View v) {
                 // 開始朗讀

                 mSpeech.speak(ev.getText().toString(),
                         TextToSpeech.QUEUE_FLUSH, null);
             }
         });

  }

}
