关键字发现:假设是空的,直到它恰好是您要查找的关键字之一

Keywords spotting: hypotesis is null until it is exactly one of the keyword you are looking for

我正在使用 onPartialResult 方法来查看 hypotesis 是否是我感兴趣的关键字之一并且效果很好。

这是我的代码:

@Override
public void onPartialResult(Hypothesis hypothesis) {
    Log.d(TAG, "onPartialResult");

    if (hypothesis == null) {
        return;
    }

    String text = hypothesis.getHypstr();

    String wordWithProb = "";
    String mostProbableWord = "";
    int probability = -10000;

    if (text.contains("|")) {
        for (Segment seg : recognizer.getDecoder().seg()) {
            wordWithProb += "|" + seg.getWord() + " " + seg.getProb() + "|";
            if (seg.getProb() > probability)
                mostProbableWord = seg.getWord().trim();
        }
    }
    else
        mostProbableWord = text.trim();

    Log.i(TAG, "onPartialResults: " + mostProbableWord);

    String recognizedCommand = "Please repeat";
    if (mostProbableWord.equals("one")) {
       //do something...
    } else if (mostProbableWord.equals("two")) {
       //do something...
    } else if (mostProbableWord.equals("three")) {
       //do something...
    } 

    //text to speech
    speak(recognizedCommand);

    startListening(KWS_SEARCH);
}

现在我想处理用户说了些什么但不被识别为关键字的情况;在这种情况下,onPartialResult 方法中的假设总是 null:这是预期的吗? 我期待这里的假设不为空...
考虑到 onPartialResult 方法被 pocketsphinx 连续自动调用(即使空气中没有任何声音)我不能使用 null 假设作为我的驾驶条件。
此外,每次识别后都有一个文本到语音,因此必须小心处理识别侦听器的重启:在文本到语音正在进行时,识别器不能正在收听...
我用 onEndOfSpeech 尝试了一些解决方案,但 none 直到现在都很好...... 有什么想法吗?

in this case the hypotesis in the onPartialResult method is always null: is this expected?

Moreover there is a text to speech after every recognition and so the recognition listener restart has to be handled carefully: recognizer must not be listening while text to speech is ongoing
