我试图让Android TTS API读取我的“话语”,然后调用onUtteranceCompleted()监听器失败。我已经注册了我的TTS对象,它返回SUCCESS,所以我无法弄清楚为什么我的回调没有被调用。
我试过寻求帮助,但似乎其他人也有这方面的困难。我错过了一些简单的东西吗?
感谢您提供的任何帮助。

在tts对象的onInit函数内调用setOnUtteranceCompletedListener。
如果要在调用onUtteranceCompleted函数时对UI进行任何更改,请在runOnUIThread方法中添加代码。
并且记得在调用speak()函数时添加Hashmap参数值
示例:
TextToSpeech tts= new TextToSpeech(context, new OnInitListener() {
@Override
public void onInit(int status) {
mTts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
@Override
public void onUtteranceCompleted(String utteranceId) {
runOnUiThread(new Runnable() {
@Override
public void run() {
//UI changes
}
});
}
});
}
});
HashMap<String, String> params = new HashMap<String, String>();
params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
tts.speak("Text to Speak",TextToSpeech.QUEUE_FLUSH, params);

我相信除非你指定一个带有id的话语,例如:
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, utteranceid);
你的话语完成方法不会被调用。
在这种情况下,map是你说话时传递给引擎的Hashmap。

万一仍然有人觉得困难
代码段
textToSpeech=new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status==TextToSpeech.SUCCESS){
int result=textToSpeech.setLanguage(Locale.ENGLISH);
if (result==TextToSpeech.LANG_MISSING_DATA||result==TextToSpeech.LANG_NOT_SUPPORTED){
Log.i("TextToSpeech","Language Not Supported");
}
textToSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() {
@Override
public void onStart(String utteranceId) {
Log.i("TextToSpeech","On Start");
}
@Override
public void onDone(String utteranceId) {
Log.i("TextToSpeech","On Done");
}
@Override
public void onError(String utteranceId) {
Log.i("TextToSpeech","On Error");
}
});
}else {
Log.i("TextToSpeech","Initialization Failed");
}
}
});
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
textToSpeech.speak(text,TextToSpeech.QUEUE_FLUSH,null,TextToSpeech.ACTION_TTS_QUEUE_PROCESSING_COMPLETED);
}
