如何知道TextToSpeech何时讲完？

我正在为Android应用程序使用Text to Speech。我很困惑找到一个在Text to Speech完成后调用的方法。我试着调用以下方法，但是没有调用完成的，请查看以下代码并建议我。

 tts= new TextToSpeech(MainActivity.this, new OnInitListener() {

         @Override
         public void onInit(int status) {

             tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

                @Override
                public void onUtteranceCompleted(final String utteranceId) {
                            System.out.println("Completed");

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                        //UI changes
                        }
                    });
                }
            });

         }
        });

请建议我。我使用的是API Level 17。

最低API级别为12;

我在控制台中收到以下错误：

问题不在onUtteranceComplete函数中，最有可能被调用，但您尝试将输出打印到System.out，请改用android.utils.Log("tag", "success")，看看会发生什么。

此外，您需要设置UtteranceID才能使onUtteranceComplete生效 在调用tts.speak方法之前。总结一下：

            TextToSpeech tts= new TextToSpeech(MainActivity.this, new OnInitListener() {

         @Override
         public void onInit(int status) {

             tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

                @Override
                public void onUtteranceCompleted(final String utteranceId) {
                            System.out.println("Completed");

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                        //UI changes
                        }
                    });
                }
            });

         }
    });
    Map<String,String> ttsParams = new HashMap<String, String>();
    ttsParams.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,
            MainActivity.this.getPackageName());

    mTts.speak(text, TextToSpeech.QUEUE_FLUSH, ttsParams);

您获得的例外与onUtteranceComplete方法无关，如果是因为tts引擎很可能是您在完成活动时没有请求销毁您的实例。

修复添加

@Override
onDestroy(){
super.onDestroy();
mTts.shutdown(); //mTts is your TextToSpeech Object
}

到您的活动类

从API级别15开始，您必须使用setOnUtteranceProgressListener代替setOnUtteranceCompletedListener

检查official doc

试试这个：

if(tts.myTTS.isSpeaking())

你得到一个布尔值。

我找到了＆＃34;话语＆＃34;是合成文件。

使用 while（！utteranceDone）{thread.sleep ...} 和以下代码发言：

                                brTTS = new BroadcastReceiver(){
                                public void onReceive(Context p1, Intent p2) {
                                    //Log.d(TAG,"TTS ACTION_TTS_QUEUE_PROCESSING_COMPLETED, p2.getAction()="+p2.getAction()+", ? "+TextToSpeech.ACTION_TTS_QUEUE_PROCESSING_COMPLETED);
                                    if (p2.getAction().equals(TextToSpeech.ACTION_TTS_QUEUE_PROCESSING_COMPLETED) && tts != null) {
                                        utteranceDone=true;
                                    }
                                }
                            };
                            registerReceiver(brTTS, new IntentFilter(TextToSpeech.ACTION_TTS_QUEUE_PROCESSING_COMPLETED));
