Unity语法识别器无效

Question

我正在尝试使用Unity的Windows 10语法识别器，但没有检测到任何内容。

private GrammarRecognizer grammarRecognizer;

在开始函数上，我有：

grammarRecognizer = new GrammarRecognizer(Application.streamingAssetsPath + "/SRGS/myGrammar.xml", ConfidenceLevel.Low);
grammarRecognizer.OnPhraseRecognized += grammarRecognizer_OnPhraseRecognized;
grammarRecognizer.Start();

我也具有此功能：

void grammarRecognizer_OnPhraseRecognized(PhraseRecognizedEventArgs args)
{
    System.Action keywordAction;
    Debug.Log("word said: " + args.text + " - conf: " + args.confidence);
    if (args.confidence >= ConfidenceLevel.Medium) 
        Debug.Log("Confidence is low");
    print(args.semanticMeanings);
}

但是，以前的功能从未被调用，因为它永远不会识别任何东西。我有这个语法：

<grammar version="1.0" xml:lang="en-US" root="playCommands"
 xmlns="http://www.w3.org/2001/06/grammar">
  <rule id="playCommands">
    <ruleref uri="#playAction" />
    <item> the </item>
    <ruleref uri="#fileWords" />
  </rule>
  <rule id="playAction">
    <one-of>
      <item> play </item>
      <item> start </item>
      <item> begin </item>
    </one-of>
  </rule>
  <rule id="fileWords">
    <one-of>
      <item> song </item>
      <item> tune </item>
      <item> track </item>
      <item> item </item>
    </one-of>
  </rule>
</grammar>
