Defaultapppoll>>Properties>>Identity>>Predefine>>Local System

 And >>**Restart IIS**

Did you restart your iis ?

Edit:

This is something related with the user account running the application. If you running the application on the IIS, the account is Network Service in IIS6.0 and ASPNET in IIS5.0. The two account doesn't hava access right to the SpeechLib. You should modify the account which is running the Web application.

If you are using IIS6.0, there is a application pool which your web application exists in. Change the identity of the Application Pool to Loal System and then your application will run.
