speechLib not working on asp.net page RRS feed

  • Question

  • I am trying to speak a firstname greeting to my users when they visit my web page, but I get:


    COMException (0x8004503a): Exception from HRESULT: 0x8004503A]

    Here is my code:

    Imports SpeechLib
    Public Class t2
        Inherits System.Web.UI.Page
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            Dim Voice As New SpVoice
            Voice.Speak("Hi John")
        End Sub

    It works fine when I run it on my dev machine, but when I upload it to the Windows 2008 x64 R2 server, I get the error above.
    Any ideas?

  • speechlib work on server side not client side so you should create wave file and play it in user web page 
    this code may help you 
     protected void Button1_Click(object sender, EventArgs e)
          SpVoice v = new SpVoice();
          SpeechLib.SpFileStream speechStream = new SpeechLib.SpFileStream();
          speechStream .Open(Server.MapPath("~/test.wav"), SpeechLib.SpeechStreamFileMode.SSFMCreateForWrite, false);
          v.AudioOutputStream = speechStream;
          v.Volume = 100;
          v.Rate = -1;
          //// speak "hello world" or any string else 
          v.Speak("hello world", SpeechLib.SpeechVoiceSpeakFlags.SVSFDefault);
          Response.Write("<EMBED src='test.wav' hidden=true volume='100' type=audio/x-wav LOOP='FALSE' AUTOSTART='TRUE'></EMBED>");
          v = null;
          speechStream = null;
            /// user need to set up QuickTime to make browser play sound

  •  VB.net code :

        Protected Sub Page_Load(ByVal sender As ObjectByVal As EventArgs)
    Dim As SpVoice = New SpVoice
    Dim speechStream As SpeechLib.SpFileStream = New SpeechLib.SpFileStream
    "~/test.wav"), SpeechLib.SpeechStreamFileMode.SSFMCreateForWrite, false)
    v.Rate -1
    '''/ speak "hello world" or any string else 
    v.Speak("hello world", SpeechLib.SpeechVoiceSpeakFlags.SVSFDefault)
    "<EMBED src='test.wav' hidden=true volume='100' type=audio/x-wav LOOP='FALSE' AUTOSTART='TRUE'></EMBED>")
    ''' user need to set up QuickTime to make browser play sound 
    End Sub
