Mr/Sir..
I am developing a speech recognition in vb.net. How to code a function when user say something, eg: "CAT", system will reply "CORRECT" .

Here is an example code that i found, but it do not work:

VB

'CODE1)
    Private Sub recognizer_SpeechRecognized(ByVal sender As Object, ByVal e As SpeechRecognizedEventArgs)
    
Dim objSpeechToSpeech As Object
 objSpeechToSpeech = CreateObject("SAPI.spvoice")

Select Case e.Result.Text
         Case "CAT"
         objSpeechToSpeech.Speak("correct")
        End Select
End Sub

VB

'CODE2)

Private Sub DirectSR1_PhraseFinish(ByVal flags As Long, ByVal beginhi As Long, ByVal beginlo As Long, ByVal endhi As Long, ByVal endlo As Long, ByVal Phrase As String, ByVal parsed As String, ByVal results As Long)
       
      Dim objSpeechToSpeech As Object
      objSpeechToSpeech = CreateObject("SAPI.spVoice")
       If Phrase = "CAT" Then
      objSpeechToSpeech.Speak("Correct")
     End If
    End Sub

Any correction?
Could you help me if there is any other way?

SpeechRecognizer Class[^]

C#

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    _recognizer = new SpeechRecognizer();
    _recognizer.Enabled = true;
    _recognizer.SpeechRecognized += OnSpeechRecognized;
}
private void OnSpeechRecognized(object sender, SpeechRecognizedEventArgs eventArgs)
{
    if( eventArgs.Result.Text == "cat")
    {
        object spVoice = CreateObject( "SAPI.SpVoice");
        spVoice.Speek( "correct");
    }
}

Thank you very much for the reply.. my ques is about speech-to-speech.. where.. when user say "CAT", system will reply "CORRECT" by speech. But according to your code.. if( eventArgs.Result.Text == "cat").. "Text" exist in your code. There is no text in my system.. because im developing learning system for blind people.. comunicating by speeh-to-speech. Is your code is what i need? or any other code for my ques.. thank you Radhakrishnan sir.. reply please..
