Text to Speech in ASP.NET - Access is denied... what to do?
- by Magnetic_dud
On my personal website, i would like to make it "pronounce" something
I solved the "concept" problem, as in here, and on my desktop it works smoothly when launched from visual web developer. Creates a file, and then an embedded player in the page will play it. Perfect.
So, I uploaded it on the server... I get this error 500:
Server Error in '/sapi' Application.
Access is denied. (Exception from
HRESULT: 0x80070005 (E_ACCESSDENIED))
Description: An unhandled exception
occurred during the execution of the
current web request. Please review the
stack trace for more information about
the error and where it originated in
the code.
Exception Details:
System.UnauthorizedAccessException:
Access is denied. (Exception from
HRESULT: 0x80070005 (E_ACCESSDENIED))
ASP.NET is not authorized to access
the requested resource. Consider
granting access rights to the resource
to the ASP.NET request identity.
ASP.NET has a base process identity
(typically {MACHINE}\ASPNET on IIS 5
or Network Service on IIS 6) that is
used if the application is not
impersonating. If the application is
impersonating via , the identity
will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated
request user.

I get error on line 21, Voice.speak
That probably means that the aspnet worker user has not some right permission
The generation folder has all the right permissions: an empty file is created.
So, i have to give permission of execute to some system dll?
Do you know which dll? It is not bin\Interop.SpeechLib.dll, on this one the aspnet user has full control
Ps: i have full control on the (windows) server (i mean, access by RDC, is not a shared hosting)
