voice based commands for media player

[Nuzhat Fatima]

Hi,
I am student of BS IT and now making a voice based software for blind people so that they may use the system by giving voice commands to read/write files, emails and also listen songs through my software.

But I am currently stuck in my one activity that is to make media player controls as voice controls.

User say pause and media player would perform action on this command "pause" and similar for stop and play.

I used following code and add windows media player as its reference

Imports System.Speech.Recognition
 
Public Class Form2
 
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AxWindowsMediaPlayer1.URL = "songs playlist"       
 Dim engine As New Speech.Recognition.SpeechRecognitionEngine
 
        Dim dictionGrammar As New Speech.Recognition.DictationGrammar
 
        Dim recognitionResult As Speech.Recognition.RecognitionResult
 
        Dim timeSpan As New TimeSpan(0, 0, 15)
 
        engine.SetInputToDefaultAudioDevice()
 
        engine.LoadGrammar(dictionGrammar)
 
        recognitionResult = engine.Recognize(timeSpan)
 
        For Each word As RecognizedWordUnit In recognitionResult.Words
 
 
 
            MessageBox.Show(word.Text)
            If word.Text = "play" Then
                AxWindowsMediaPlayer1.Ctlcontrols.play()
            ElseIf word.Text = "pause" Then
                'Process.Start("pause")
                AxWindowsMediaPlayer1.Ctlcontrols.pause()
            ElseIf word.Text = "stop" Then
                ' Process.Start("stop")
                AxWindowsMediaPlayer1.Ctlcontrols.stop()
                        End If
        Next
 
    End Sub
End Class

Please help me in my task
