C# 语音识别后想把输出从中文变成英文

using System;
using System.IO;
using System.Speech.Recognition;
using System.Speech.AudioFormat;

namespace SampleRecognition
{
class Program
{
static bool completed;

static void Main(string[] args)

// Initialize an in-process speech recognition engine.
{
using (SpeechRecognitionEngine recognizer =
new SpeechRecognitionEngine())
{

// Create and load a grammar.
Grammar dictation = new DictationGrammar();
dictation.Name = "Dictation Grammar";

recognizer.LoadGrammar(dictation);

// Configure the input to the recognizer.
recognizer.SetInputToWaveFile(@"c:\temp\green.wav");

// Attach event handlers for the results of recognition.
recognizer.SpeechRecognized +=
new EventHandler(recognizer_SpeechRecognized);
recognizer.RecognizeCompleted +=
new EventHandler(recognizer_RecognizeCompleted);

// Perform recognition on the entire file.
Console.WriteLine("Starting asynchronous recognition...");

recognizer.RecognizeAsync();

// Keep the console window open.
while (!completed)
{
Console.ReadLine();
}
Console.WriteLine("Done.");
}

Console.WriteLine();
Console.WriteLine("Press any key to exit...");
Console.ReadKey();
}

// Handle the SpeechRecognized event.

{
if (e.Result != null && e.Result.Text != null)
{
Console.WriteLine(" Recognized text = {0}", e.Result.Text);
}
else
{
Console.WriteLine(" Recognized text not available.");
}
}

// Handle the RecognizeCompleted event.
static void recognizer_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e)
{
if (e.Error != null)
{
Console.WriteLine(" Error encountered, {0}: {1}",
e.Error.GetType().Name, e.Error.Message);

}

这是msdn里的范例源码， 我green.wva文件里的音频是green一个单词，识别出来之后输出是中文“图林”，我需要怎么把他改成英文并且正确识别呢？

我自己本身是中文的win7操作系统

涉及到语音识别，是研究生的课题，拿来百度知道问似乎不妥。

sapi.51 sdk能实现文字语言输出，你说的发音输出文字，应该也不是问题，看看它的msdn相关帮助吧
