how to limit commands recognized in IE?

Hi,

I'm a newbie to Windows speech recognition but an experienced programmer. I have developed a web application that runs in Internet Explorer, with commands triggered by speech recognition. The problem is that too many commands are recognized. I need to limit speech recognition to a small set of commands, in other words, I need to define a grammar.

Ideally, my grammar will have effect only on my browser windows. But if it affects everything in Internet Explorer, that is also satisfactory. In fact, I would be pleased even if my grammar affects all current speech recognition system wide.

My question is: what would be the easiest, most effective way to define such a grammar? My laptop runs Windows Vista so I would like to start there. My web application uses Adobe Flex if that is relevant.

Thank you very much for your help,
Peter

Thanks for the suggestion Marty. I did learn that the Windows SDK for Vista includes SAPI. My question now is how to activate the grammar so that the default speech recognition engine, or the engine that Internet Explorer is using, is constrained by the grammar. Inch by inch ;-)

Thanks again, Marty, I appreciate your attention.

I would like to understand your comment about speech macros. Are you saying that I can use speech macros to designate the grammar for Internet Explorer?

Or are you saying that since speech macros have this ability, then you believe I will find a similar ability that I can express in, for example, a Visual Basic application?

I'm still trying to figure out my approach, for example, at the moment I'm working through an example using Visual Basic.

Thanks,
Peter
