How to change Windows Speech Recognition output?

I am writing my first speech recognition application by using the System.Speech namespace of .NET Framework 4.0.

I am using the shared speech recognition, loading a default dictation grammar and custom grammars I've done.

I also capture the text recognized by the Windows Speech Recognizer (WSR) by implementing a handler for the event "SpeechRecognized".

I would like to change the text recognized (e.g. to change "two" by "2" in the text) but if I do that, the output will not be written in the current app (e.g. MS Word).

I know I can do something SIMILAR by using the SendKeys method, but I think it's not a good idea because the quality of the output is lower. For example, if you use WSR as a standard user, you will see that after "." or a new line the follow开发者_StackOverflow中文版ing sentence starts with an uppercase character. There're tons of things you must take into account if you want to write your own output parser so I would like to use the one WSR uses if you don't handle the SpeechRecognized event. But... HOW??

(I wouldn't mind to use SAPI if necessary).

Thanks!!

The short answer is that you can't. WSR doesn't have a hook that allows 3rd parties to connect into its dictation pipeline.
