UtteranceProgressListener 不同步

Question

总结

• 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，TTS 工作
• 似乎有时在 UtteranceProgressListener 完成当前话语之前调用了我的方法“sayThis”

我认为流程应该如下：

1) 调用方法“sayThis”，如果 voiceReady=true
2) TTS 启动话语并调用 UtteranceProgressListener onStart 并将 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) 可以再次调用方法“sayThis”，因为 voiceReady=true
6) 上面应该继续，直到话语数组被循环完成

    //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 会指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

关于如何同步流程有什么建议吗？

这几乎就像遍历数组并调用“sayThis”方法比 UtteranceProgressListener 可以跟上切换“voiceReady”布尔值的真/假值更快。

如果我无法准确地检测到每个话语何时完成，这将对我造成流量控制问题。

谢谢

创建类成员

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

将您的话语保存在mUtterances，然后调用sayThis(mUtterances.get(0), 0)

然后onDone调用下一个sayThis

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