如何知道什么时候TTS完成？ [英] How to know when TTS is finished?

问题描述

我实现在Android上的交互式语音应答应用。我想知道如何确定何时 tts.speak（）功能做了交谈，所以我可以叫我的语音识别功能。

解决方案

 公共类TTSActivity扩展活动实现OnInitListener，OnUtteranceCompletedListener，... {
私人TextToSpeech MTTS;
...........
私人无效讲（文本字符串）{
   如果（文字！= NULL）{
      HashMap的＆LT;字符串，字符串＆GT; myHashAlarm =新的HashMap＆LT;字符串，字符串＆GT;（）;
      myHashAlarm.put（TextToSpeech.Engine.KEY_PARAM_STREAM，将String.valueOf（AudioManager.STREAM_ALARM））;
      myHashAlarm.put（TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID，有些消息）;
      mTts.speak（文字，TextToSpeech.QUEUE_FLUSH，myHashAlarm）;
   }
}
// TTS初始化后激发
公共无效的OnInit（INT状态）{
    如果（状态== TextToSpeech.SUCCESS）{
        mTts.setOnUtteranceCompletedListener（本）;
    }
}
//这是回调
公共无效onUtteranceCompleted（字符串utteranceId）{
   Log.i（TAG，utteranceId）; // utteranceId ==某个消息
   }
...........
}
 

读 一个很好的教程

I'm implementing an Interactive Voice Response application on Android. I would like to know how to determine when the tts.speak() function has done talking so I can call my speech recognizer function.

解决方案

public class TTSActivity extends Activity implements OnInitListener, OnUtteranceCompletedListener, ... {
private TextToSpeech mTts;
...........
private void speak(String text) {
   if(text != null) {
      HashMap<String, String> myHashAlarm = new HashMap<String, String>();
      myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_ALARM));
      myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "SOME MESSAGE");
      mTts.speak(text, TextToSpeech.QUEUE_FLUSH, myHashAlarm);
   }
}
// Fired after TTS initialization
public void onInit(int status) {
    if(status == TextToSpeech.SUCCESS) {
        mTts.setOnUtteranceCompletedListener(this);
    }
}
// It's callback
public void onUtteranceCompleted(String utteranceId) {
   Log.i(TAG, utteranceId); //utteranceId == "SOME MESSAGE"
   }
...........
}
