Members

• ulAudioTimeOffset
  The starting offset of the element in 100-nanosecond units of time relative to the start of the phrase.
• ulAudioSizeTime
  The length of the element in 100-nanosecond units of time.
• ulAudioStreamOffset
  The starting offset of the element in bytes relative to the start of the phrase in the original input stream.
• ulAudioSizeBytes
  The size of the element in bytes in the original input stream.
• ulRetainedStreamOffset
  The starting offset of the element in bytes relative to the start of the phrase in the retained audio stream
• ulRetainedSizeBytes
  The size of the element in bytes in the retained audio stream.
• pszDisplayText
  The display text for this element (for example, ",").
• pszLexicalForm
  The lexical form of this element (for example, "comma" for ",").
• pszPronunciation
  The pronunciation for this element as a null-terminated array of SPPHONEID.
• bDisplayAttributes
  A bit field of SPDISPLAYATTRIBUTES defining extra display information which the application should honor when displaying this word.
• RequiredConfidence
  The required confidence for this element (either SP_LOW_CONFIDENCE, SP_NORMAL_CONFIDENCE, or SP_HIGH_CONFIDENCE). If a word is prefixed with a '-' (minus), the RequiredConfidence is SP_LOW_CONFIDENCE, and '+' (plus) will set this field to SP_HIGH_CONFIDENCE (for example, "This -is -a +test").
• ActualConfidence
  The actual confidence for this element (either SP_LOW_CONFIDENCE, SP_NORMAL_CONFIDENCE, or SP_HIGH_CONFIDENCE). This is always at least the RequiredConfidence.
• Reserved
  Reserved for future use.
• SREngineConfidence
  The confidence score computed by the SR engine. The value range is engine dependent. It can be used to optimize an application's performance with a specific engine. Using this value will improve the application with a particular speech engine but more than likely will make it worse with other engines and should be used with care. This value is more useful with speaker-independent engines because it allows a large corpus of recorded usage to correctly optimize the overall accuracy of the application.
