<pre>using System;
using System.Speech.Recognition;

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

// Create an in-process speech recognizer for the en-US locale.
using (
SpeechRecognitionEngine recognizer =
new SpeechRecognitionEngine(
new System.Globalization.CultureInfo("en-US")))
{

// Create and load a dictation grammar.
recognizer.LoadGrammar(new DictationGrammar());

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

// Configure 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();
}
}
}

// Handle the SpeechRecognized event.
static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine("Recognized text: " + e.Result.Text);
}
}
}
