Members
- AudioStatus
SPAUDIOSTATUS structure containing current audio device information.
- ullRecognitionStreamPos
Stream position, in bytes, up to which the engine has currently recognized. This value can be used to see how the engine is progressing through the audio data.
- ulStreamNumber
Stream number. This value is incremented every time SAPI starts or stops recognition on an engine (see SPEI_START_SR_STREAM and SPEI_END_SR_STREAM defined for SPEVENTENUM). Each time this happens the stream position (ullRecognitionStreamPos) is reset to zero. Events fired by the engine have equivalent stream number and position information.
- ulNumActive
Number of active rules for the current engine.
- clsidEngine
Unique identifier associated with the current engine.
- cLangIDs
Number of languages that the current engine supports.
- aLangID
Array of identifiers for the languages that the current engine supports.
- dwReserved1
Reserved for future expansion.
- dwReserved2
Reserved for future expansion.
