I'm trying to use the System.Speech.Recognition namespace for recognizing speech in a web service. Actually, the WS calls a dll that uses this namespace.

The problem is that...I can't. First, I had a Access denied error. After changing the Identity of my application pool to LocalSystem (security break, I know), that disappeared. But a timeout appeared. I receive no error, but no response either.

I did some tests, and, the same code (very simple) that I use for recognizing the text in a WAV returns the answer in around 2 seconds, when integrated in a desktop application, but hangs and does nothing in a web application.

I think I'm missing something... I'm not supposed to use System.Speech.Recognition in a web application? Am I supposed to use something else?

Any help is greatly appreciated.

Thank you!
