This member is overloaded. For complete information about this member, including syntax, usage, and examples, click a name in the overload list.

  Name Description
Public method EmulateRecognize(String) Emulates input of a phrase to the shared speech recognizer, using text instead of audio for synchronous speech recognition.
Public method EmulateRecognize(RecognizedWordUnit[], CompareOptions) Emulates input of specific words to the shared speech recognizer, using text instead of audio for synchronous speech recognition, and specifies how the recognizer handles Unicode comparison between the words and the loaded speech recognition grammars.
Public method EmulateRecognize(String, CompareOptions) Emulates input of a phrase to the shared speech recognizer, using text instead of audio for synchronous speech recognition, and specifies how the recognizer handles Unicode comparison between the phrase and the loaded speech recognition grammars.

These methods bypass the system audio input. This can be helpful when you are testing or debugging an application or grammar.

Note Note

If Windows Speech Recognition is in the Sleeping state, then these methods return null.

The shared recognizer raises the SpeechDetected, SpeechHypothesized, SpeechRecognitionRejected, and SpeechRecognized events as if the recognition operation is not emulated. The recognizer ignores new lines and extra white space and treats punctuation as literal input.

Note Note

The RecognitionResult object generated by the shared recognizer in response to emulated input has a value of null for its Audio property.

To emulate asynchronous recognition, use the EmulateRecognizeAsync method.
