Microsoft.Speech.dll中發生未處理的異常類型'System.FormatException'

Question

我剛剛嘗試使用來自thr鏈接http://msdn.microsoft.com/en-us/library/hh378403(v=office.14).aspx的PLS詞典使用自定義發音。 我的.pls文件如下

Additional information：詞典數據無效或損壞。

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

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()); 
     } 
} 

但每當我嘗試編譯它，並用它來recognisig「規模」，它總是顯示「類型的未處理的異常「System.FormatException '發生在Microsoft.Speech.dll 附加信息：詞典數據無效或損壞。「

雖然使用內聯語音，但它的工作原理是在外部發音鏈接似乎不起作用。 有什麼解決方法嗎？任何幫助，將不勝感激。請。

將上面的代碼從Microsoft.Speech.Recogonition移動到System.Speech.Recognition可以解決上述格式異常的問題。

至於爲什麼Microsoft.Speech.Recognition正在拋出錯誤，我不確定。我知道的官方W3C規範並正式支持在XML文件中的詞彙標籤（雖然微軟有非常具體的規則到詞庫標籤應該位於這似乎是正確的）：

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

詞彙表：語法格式不能解決詞典的加載或語法引用的單詞的發音問題。 W3C語音瀏覽器工作組正在考慮開發標準詞典格式。如果並且當一種格式被開發時，將對該語法規範進行適當的更新。

的詞庫格式的實際規格尚未完成：

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

總而言之，如果微軟自己的例子鏈接here不起作用，這似乎是一個錯誤。特別是如果你所做的只是修改格式異常，就是從Microsoft.Speech改爲System.Speech。
