Audio Query

I am using the file “Interop.SpeechLib.dll” for Text to Speech.

Public WithEvents vox As New SpVoice

Private Sub btnToRead_Click(…

vox.Speak(txtToRead.Text , SpeechVoiceSpeakFlags.SVSFlagsAsync)

End Sub

Private Sub btnPause_Click(…
vox.Pause()
End Sub

Private Sub btnResume_Click(…
vox.Resume()
End Sub

Private Sub btnStopRead_Click(…
vox.Speak(“”, SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak) ’ For Stop
End Sub

The above code runs fine.

But if I want the btnStopRead to be enabled until the text is read, then I have to change the code a little

btnStopRead.Enabled = True
vox.Speak(txtToRead.Text, SpeechVoiceSpeakFlags.SVSFlagsAsync)
vox.WaitUntilDone(…)
btnStopRead.Enabled = False

OR

btnStopRead.Enabled = True
vox.Speak(txtToRead.Text , SpeechVoiceSpeakFlags.SVSFDefault)
btnStopRead.Enabled = False

But when I use this code, the Pause, Resume, Stop buttons are not working properly.

btnStopRead.Enabled = True
vox.Speak(txtToRead.Text, SpeechVoiceSpeakFlags.SVSFlagsAsync)
btnStopRead.Enabled = False

This code does not work properly.

Can anyone provide any solution?

Thanks

Actually I like to know how I can trap the event something like EndSpeechText.
Thanks

Is there no other way?
Can anyone at least tell me about some other DLL that performs the same job. I may purchase that.

Thanks
