SpeechRecognitionEngine.SetInputToWaveStream Method (Stream)
Configures the SpeechRecognitionEngine object to receive input from a stream that contains Waveform audio format (.wav) data.
Assembly: System.Speech (in System.Speech.dll)
If the recognizer reaches the end of the input stream during a recognition operation, the recognition operation finalizes with the available input. Any subsequent recognition operations can generate an exception, unless you update the input to the recognizer.
