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.

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.
