Automation Interfaces

The ISpeechRecoContext (Events) automation interface contains the following elements:

Events	Description
Adaptation Event	Occurs when the SR engine has finished processing a block of adaptation data.
AudioLevel Event	Occurs when the SAPI audio object detects a change in audio level.
Bookmark Event	Occurs when the SR engine encounters a bookmark within the current recognition stream.
EndStream Event	Occurs when the SR engine encounters the end of an input audio stream.
EnginePrivate Event	Occurs when a private SR engine raises a private event.
FalseRecognition Event	Occurs when the SR engine produces a false recognition.
Hypothesis Event	Occurs when the SR engine produces a hypothesis.
Interference Event	Occurs when the SR engine encounters interference in the input audio stream.
PhraseStart Event	Occurs when the SR engine identifies the start of a phrase.
PropertyNumberChange Event	Occurs when the speech recognition engine detects a change in a property number value.
PropertyStringChange Event	Occurs when the speech recognition engine detects a change in a property String value.
Recognition Event	Occurs when the SR engine produces a recognition.
RecognitionForOtherContext Event	Occurs when the recognition context encounters a recognition result that belongs to another recognition context.
RecognizerStateChange Event	Occurs when the SR engine changes state.
RequestUI Event	Occurs when the SR engine requests additional information from the user.
SoundEnd Event	Occurs when the SR engine encounters an end of sound in the audio input stream.
SoundStart Event	Occurs when the SR engine encounters the start of sound in the audio input stream.
