I'm creating a wrapper to a recognizer based on SR engine sample
provided in SAPI 5.1 SDK.
When I use the engine with Listbox sample (C# - SAPI 5.1 SDK) the
confidence values are being successfully sent from engine to
application (through Interop.SpeechLib).
When I use the same engine in System.Speech (.Net 3.0) the confidence
values tha application gets are always -1.
What should be changed in the sample SR engine in order to make it
compatible with SAPI 5.3? Is there any doc that explains how
System.Speech gets confidence values from an recognizer?

Thanks
Renato

Hi Renato - did you manage to figure this out? I'm getting the same issue of -1 in the confidence value...
