Microsoft.Speech.dll中发生未处理的异常类型'System.FormatException'

Question

我刚刚尝试使用来自thr链接http://msdn.microsoft.com/en-us/library/hh378403(v=office.14).aspx的PLS词典使用自定义发音。 我的.pls文件如下

Additional information：词典数据无效或损坏。

    <lexeme> 
     <grapheme> scale </grapheme> 
     <phoneme> S K A L E </phoneme> 
    </lexeme> 
</lexicon> 

and my grammar file is as pronunciation.grxml 


<?xml version="1.0" encoding="UTF-8"?> 
<grammar 
    version="1.0" 
    xml:lang="en-US" 
    root="colors"

     <one-of> 
     <item> scale </item> 
     </one-of> 
    </rule> 

</grammar> 

和我的C＃程序是

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.IO; 
using System.Xml; 
using Microsoft.Speech; 
using Microsoft.Speech.Recognition; 
using Microsoft.Speech.Recognition.SrgsGrammar; 

namespace ConsoleApplication5 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 

      using (SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"))) 
      { 

       String currDirPath = Environment.CurrentDirectory; 

       string xmlGrammar = currDirPath + "\\pronunciation.grxml"; 
       string cfgGrammar = currDirPath + "\\pronunciation.cfg"; 
       FileStream fs = new FileStream(cfgGrammar, FileMode.Create); 
       XmlReader reader = XmlReader.Create(xmlGrammar); 

       //compile the grammar *.grxml to *.cfg file. 
       SrgsGrammarCompiler.Compile(reader, (Stream)fs); 
       fs.Close(); 
       Grammar g = new Grammar(cfgGrammar, "colors"); 
       Console.WriteLine(currDirPath+cfgGrammar); 

       recognizer.LoadGrammarAsync(g); 

       // Add a handler for the speech recognized event. 
       recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized); 
       // Configure the input to the speech recognizer. 
       recognizer.SetInputToDefaultAudioDevice(); 

       // Start asynchronous, continuous speech recognition. 
       recognizer.RecognizeAsync(RecognizeMode.Multiple); 

       // Keep the console window open. 
       while (true) 
       { 
        Console.ReadLine(); 
       } 
      } 
     } 

     // speech recognised event handler 

     static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) 
     { 
      string lines = e.Result.Text; 
      Console.WriteLine("Speak loudly"); 
      Console.WriteLine("Recognized text: " + e.Result.Text); 
      Console.WriteLine("semantic value: " + e.Result.Semantics.Value.ToString()); 
     } 
} 

但每当我尝试编译它，并用它来recognisig“规模”，它总是显示“类型的未处理的异常“System.FormatException '发生在Microsoft.Speech.dll 附加信息：词典数据无效或损坏。“

虽然使用内联语音，但它的工作原理是在外部发音链接似乎不起作用。 有什么解决方法吗？任何帮助，将不胜感激。请。

Answer 1

将上面的代码从Microsoft.Speech.Recogonition移动到System.Speech.Recognition可以解决上述格式异常的问题。

至于为什么Microsoft.Speech.Recognition正在抛出错误，我不确定。我知道的官方W3C规范并正式支持在XML文件中的词汇标签（虽然微软有非常具体的规则到词库标签应该位于这似乎是正确的）：

http://www.w3.org/TR/speech-grammar/#S4.10

词汇表：语法格式不能解决词典的加载或语法引用的单词的发音问题。 W3C语音浏览器工作组正在考虑开发标准词典格式。如果并且当一种格式被开发时，将对该语法规范进行适当的更新。

的词库格式的实际规格尚未完成：

http://www.w3.org/TR/lexicon-reqs/#pronun

总而言之，如果微软自己的例子链接here不起作用，这似乎是一个错误。特别是如果你所做的只是修改格式异常，就是从Microsoft.Speech改为System.Speech。
