speechLib not working on asp.net page

Monday, September 26, 2011 6:06 PM

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]
   SpeechLib.ISpeechVoice.Speak(

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.Close();

speechStream = null;

/// user need to set up QuickTime to make browser play sound

}

VB.net code :

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim v As SpVoice = New SpVoice
        Dim speechStream As SpeechLib.SpFileStream = 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 = Nothing
        speechStream.Close
        speechStream = Nothing
        ''' user need to set up QuickTime to make browser play sound
    End Sub
