Members

AudioStatus

The SPAUDIOSTATUS structure containing the current audio device information.

ullRecognitionStreamPos

The current stream position the engine has recognized to. Stream positions are measured in bytes. This value can be used to check the engine's progress using the audio data.

ulStreamNumber

This value is incremented every time SAPI starts or stops recognition on an engine (see SPEI_START_SR_STREAM and SPEI_END_SR_STREAM). Each time this happens the ullRecognitionStreamPos gets reset to zero. Events fired from the engine have equivalent stream number and position information also.

ulNumActive

The current engine's number of active rules.

clsidEngine

The unique identifier associated with the current engine.

cLangIDs

The number of languages that the current engine supports.

aLangID

Array containing the languages that the current engine supports.

dwReserved1

Reserved for future expansion.

dwReserved2

Reserved for future expansion.
