using SpeechLib;
using System.Threading;

private void button1_Click(object sender, EventArgs e)
		{
			if (textBox1.Text != "")
			{
				SpVoice voice = new SpVoice();
				voice.Volume = 100;
				voice.Speak(textBox1.Text, SpeechVoiceSpeakFlags.SVSFlagsAsync);
				voice.WaitUntilDone(Timeout.Infinite); 
			}
			else
				MessageBox.Show("Please enter text for speech","Text to Speech", MessageBoxButtons.OK,MessageBoxIcon.Information); 
		}

This is the my code. This code only converts Text to Speech but i want opposite of it i.e. How to convert Speech to Text using c#.net.

Please provide me a solution as soon as possible, otherwise it will be too late.

Thanks in advance.

So,
First you need to add a SpSharedRecoContext object and create an ISpeechRecoGrammar object for it. Then Add a RecognitionHandler to it...

Add another Button and a TextBox to your form and create the objects there. Then add a handler to tie into the listeners Recognition event...

		private void btnListen_Click(object sender, EventArgs e)
		{
			// Speech Recognition Object
			SpSharedRecoContext listener;

			// Grammar object
			ISpeechRecoGrammar grammar;

			listener = new SpeechLib.SpSharedRecoContext();
			listener.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler (listener_Reco);
			grammar = listener.CreateGrammar(0);
			grammar.Dictationload("", SpeechLoadOption.SLOStatic);
			grammar.DictationSetState(SpeechRuleState.SGDSActive);
		}

		public void listener_Reco(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult Result)
		{
			string heard = Result.PhraseInfo.GetText(0, -1, true);
			textBox1.Text += heard;
		}

Hope this helps,

hi,

i want to convert wave file to Text format. i treid the below code it shows some output , but the words are not the same whats on the wave file, some words are correct and some are not correct.

no the main pbm is when i run the page it just keeps loading and not showing the output. if i put break point only i can able to see the output. What might be the pbm how to solve this?.
am new to this concept i dont know how to solve, i searched a lot for 2 days but cant find any reults.

pls help me out..

the below is the code:

SpeechRecognitionEngine RecognitionEngine;
using (RecognitionEngine = new SpeechRecognitionEngine(new CultureInfo("en-US")))
{
RecognitionEngine.SetInputToWaveFile"D:/wav/test.wav");

//RecognitionEngine.RecognizeCompleted += new EventHandler<RecognizeCompletedEventArgs>(RecognitionEngine_RecognizeCompleted); 
RecognitionEngine.LoadGrammar(new DictationGrammar());
RecognitionResult Result = RecognitionEngine.Recognize();
RecognitionEngine.RecognizeAsync(RecognizeMode.Single);

StringBuilder Output = new StringBuilder();
foreach (RecognizedWordUnit Word in Result.Words)
{
Output.Append(Word.Text + " ");
}

// RecognitionEngine.RecognizeAsyncStop();

lbl_result.Text = Output.ToString();

RecognitionEngine.Dispose();
//Dispose();

i tried using Dispose method also but no use.
how to solve this pbm. And the output should be as it is on the given wave file, is there anyway to get the exact output .
