I’m working with .NET (C#) and the speech recognition engine. I’d like to be able to load and unload grammars as my state requires them. Seems to me that this is a good way to limit the chances of getting a false positive; however, whenever I run UnloadAllGrammars() it takes almost a minute to complete sometimes.
Any idea why this would be happening?
I found that if I run SpchRecognizer.RecognizeAsyncStop() prior to UnloadAllGrammars() then there was no delay. Don’t know the guts of the speech recognizer, so I can’t justify why this is needed; but at least empirically, that allows this to work.
