UtteranceProgressListener不同步

Question

概要

• 数组中的话语列表
• 遍历数组并为每个话语调用我的方法“sayThis”
• 正在调用UtteranceProgressListener，并且TTS正常工作
• 调用我的方法“sayThis”似乎在UtteranceProgressListener完成当前话语之前被调用

我认为流程应该如下：

1）如果voiceReady = true，请拨打方法“sayThis” 2）TTS启动话语和UtteranceProgressListener onStart调用＆amp;将voiceReady设置为false
3）如果voiceReady = false，则不应调用方法“sayThis” 4）UtteranceProgressListener onDone在话语完成时调用，voiceReady = true
5）调用方法“sayThis”可以再次调用，因为voiceReady = true
6）上面应该继续，直到话语阵列循环完成为止

    //Code snippet that loops through array and calls "sayThis" method
    //There are no errors
    while(arrayCounter < utterances.size()) {
        if (voice.voiceReady == true) {
            voice.sayThis(utterances.get(arrayCounter), arrayCounter);
            arrayCounter++;
        }
    }

    //Code snippet that processes speech
    //There are no errors
    public void sayThis(String whatToSay, int utteranceID){
    Log.d(LOG_SOURCE, "sayThis method called: Utterance ID=" + utteranceID);
    voiceParams.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, Integer.toString(utteranceID));
    ttsVoice.speak(whatToSay, TextToSpeech.QUEUE_ADD, voiceParams);        
}

    //Code snippet from the UtteranceProgressListener
    //You can see from the logs the methods are being called
    @Override
    public void onStart(String utteranceID) {
        voiceReady = false;
        Log.d(LOG_SOURCE, "(ttsUtteranceListener) UtteranceProgressListener onStart " +
                "method called for utteranceID:" + utteranceID + ", voiceReady=false");
    }

    @Override
    public void onDone(String utteranceID) {
        voiceReady = true;
        Log.d(LOG_SOURCE, "(ttsUtteranceListener) UtteranceProgressListener onDone " +
                "method called for utteranceID:" + utteranceID + ", voiceReady=true");

- Logcat表示并不总是遵循这种模式，如下所示：

02-13 18:05:56.765: D/LFS_TheVoice(10645): (ttsUtteranceListener) UtteranceProgressListener onDone method called for utteranceID:7, voiceReady=true

有关如何同步流量的任何建议？
它几乎就像通过数组的迭代一样，调用“sayThis”方法比UtteranceProgressListener更快地跟上切换“voiceReady”布尔值的真/假值。

如果我无法准确检测每个话语何时完成，这将导致流量控制问题。

创建班级成员

List<String> mUtterances = new ArrayList<String>();
int mCurrentUtteranceIndex;

将您的话语保存在mUtterances中，然后拨打sayThis(mUtterances.get(0), 0)

然后onDone拨打下一个sayThis

 @Override
public void onDone(String utteranceID) {
    if (++mCurrentUtteranceIndex < mUtterances.size()) {
        sayThis(mUtterances.get(mCurrentUtteranceIndex), mCurrentUtteranceIndex);
    }
}
