SPPHRASEELEMENT (Windows CE 5.0)
This structure contains a phrase element for a spoken word.

Members
ulAudioTimeOffset
Starting offset of the element in 100-nanosecond units relative to the start of the phrase.ulAudioSizeTime
Length of the element in 100-nanosecond units.ulAudioStreamOffset
Starting offset of the element, in bytes, relative to the start of the phrase in the original input stream.ulAudioSizeBytes
Size of the element, in bytes, in the original input stream.ulRetainedStreamOffset
Starting offset of the element, in bytes, relative to the start of the phrase in the retained audio stream.ulRetainedSizeBytes
Size of the element, in bytes, in the retained audio stream.pszDisplayText
Pointer to display text for the element. For example, "2" for the spoken word "two".pszLexicalForm
Pointer to the lexical form of the element, for example, "two".pszPronunciation
Pointer to a zero-terminated array of phoneme identifiers representing the pronunciation for the element. See International Phoneme Representation.bDisplayAttributes
Bit field of attributes defining additional display information that the application should honor when displaying the phrase element. Possible values are defined for the SPDISPLAYATTRIBUTES enumeration.RequiredConfidence
Required confidence for the element. Possible values are SP_LOW_CONFIDENCE, SP_NORMAL_CONFIDENCE, and SP_HIGH_CONFIDENCE. If a word is prefixed with a minus sign (-),the required confidence is SP_LOW_CONFIDENCE. A prefix of a plus sign (+) sets the required confidence to SP_HIGH_CONFIDENCE. For example, "This -is -a +test".ActualConfidence
Actual confidence for the element. Possible values are SP_LOW_CONFIDENCE, SP_NORMAL_CONFIDENCE, and SP_HIGH_CONFIDENCE. This value always reflects at least the required confidence. See RequiredConfidence.Reserved
Reserved for future use.SREngineConfidence
Confidence score computed by the SR engine. The value range is engine-dependent, and can be used to optimize application performance with a specific engine. For example, this value can be used with speaker-independent engines, allowing use of a large amount of recorded speech to correctly optimize the overall accuracy of the application.Use this value with care. Although it will improve the application with a particular speech engine, it may make it worse with other engines.
