ISpeechRecognizerStateControl interface

The ISpeechRecognizerStateControl interface represents an object that listens to audio input and interprets the audio as speech. This interface is implemented by the SpeechRecognizer class. Derived classes may be bound to a SpeechRecognizerUx class on a XAML page by using the SpeechRecognizerUx.SpeechRecognizer property.

StopListeningAndProcessAudio()	Interrupts the current audio capture operation and starts processing on the captured audio data.
