Elements

SREStreamEnd

SR engine has reached the end of an input stream.

SRESoundStart

SR engine has detected the start of non-trivial audio data.

SRESoundEnd

SR engine has detected the end of non-trivial audio data.

SREPhraseStart

SR engine has detected the start of a recognizable phrase.

SRERecognition

SR engine's best hypothesis for the audio data.

SREHypothesis

SR engine's interim hypothesis for the result of the audio data.

SREBookmark

SR engine has reached the specified point in the audio stream.

SREPropertyNumChange

LPARAM points to a string WPARAM that is the attribute value.

SREPropertyStringChange

LPARAM pointer to a buffer. Two concatenated null-terminated strings.

SREFalseRecognition

SREInterference

LPARAM is any combination of SpeechInterference flags.

SRERequestUI

LPARAM is string.

SREStateChange

WPARAM contains new recognition state.

SREAdaptation

The adaptation buffer is now ready to be accepted.

SREStreamStart

SR engine has reached the start of an input stream.

SRERecoOtherContext
