How to control Microsoft Speech Recognition app?

I want to know if it's possible to control "Microsoft Speech Recognition" using c#.

Is it possible, for instance, to simulate the click o开发者_运维百科n "On: Listen to everything I say" programmatically using c# or python?

JRobert had the right idea.

If you were using C++, then you would call ISpRecognizer::SetRecoState(SPRST_ACTIVE), and then, if you're running on Windows 7, QI the ISpRecognizer for ISpRecognizer3 and call ISpRecognizer3::SetActiveCategory(NULL) to force the recognizer into the ON state.

But, since you're using C#, you should use System.Speech.Recognition.SpeechRecognizer and set the State property to Listening. (Note that this will not, as far as I know, switch from Sleep to On.)

Here's Microsoft's Speech API documentation, and an example in Python.
