SPRECOGNIZERSTATUS
SPRECOGNIZERSTATUS is used to report static information about the recognizer, such as supported languages, and dynamic information about the position in the stream to which the recognizer has recognized.
typedef struct SPRECOGNIZERSTATUS
{
SPAUDIOSTATUS AudioStatus;
ULONGLONG ullRecognitionStreamPos;
ULONG ulStreamNumber;
ULONG ulNumActive;
CLSID clsidEngine;
ULONG cLangIDs;
LANGID aLangID[SP_MAX_LANGIDS];

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.
- ullRecognitionStreamTime
- Returns the current position of the recognizer in the stream in 100 nanosecond units.
