我目前正在做一些关于 Webkit 语音识别的 RnD，我想创建一个特定于应用程序的语法文件。根据 W3C 定义，我编写了以下代码。但它似乎并没有显示出对这些词的识别改进的结果。你能提供一些帮助吗？

var 识别 = 新 webkitSpeechRecognition(); 识别.grammars.addFromUri("voice/api_grammar/weight.grxml");

语法文件是一个简单的文件，如下所示。

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE grammar PUBLIC "-//W3C//DTD GRAMMAR 1.0//EN"
                  "http://www.w3.org/TR/speech-grammar/grammar.dtd">

<grammar version="1.0"
         xmlns="http://www.w3.org/2001/06/grammar"

         xsi:schemaLocation="http://www.w3.org/2001/06/grammar 
                             http://www.w3.org/TR/speech-grammar/grammar.xsd"
         xml:lang="en-US" mode="voice" root="sequence">

  <meta name='description' content='Example using examples'/>

  <meta name='in.1' content='sunny Yorktown Heights New York United States'/>
  <meta name='out.1' content='$sequence[$repeat[$alternatives["sunny"]],$ruleref[$token["Yorktown Heights"]],$Token["New","York"],$TOKEN["United States"]]'/>




  <rule id="ruleref">
    <example>"Yorktown Heights"</example>
    <ruleref uri="#token"/>
  </rule>

  <rule id="alternatives">
    <example>sunny</example>
    <example>cloudy</example>
    <example>warm</example>
    <example>cold</example>
    <one-of>
      <item> sunny </item>
      <item> cloudy </item>
      <item> warm </item>
      <item> cold </item>
    </one-of>
  </rule>

  <rule id="repeat">
   <example></example> <!-- for count=0 -->
   <example>warm</example>
   <example>warm sunny cloudy</example>
   <item repeat="0-3">
      <ruleref uri="#alternatives"/>
   </item>
  </rule>

  <rule id="sequence">
    <example>
      warm sunny cloudy "Yorktown Heights" New York "United States"
    </example>
    <example>
      warm sunny cloudy   Yorktown   Heights   New York United
            States
    </example>
    <example> <!-- this example is actually wrong but that is legal -->
      warm sunny cloudy "Yorktown   Heights" New York "United States"
    </example>

    <ruleref uri="#repeat"/> <ruleref uri="#ruleref"/>
    <ruleref uri="#Token"/> <ruleref uri="#TOKEN"/>    
  </rule>

</grammar>

虽然 w3c 指定了网络语音的语法，但谷歌浏览器尚未实现。
