ISpeechPhraseElement EngineConfidence Property (SAPI 5.4)
Microsoft Speech API 5.4
The EngineConfidence property returns the confidence score computed by the speech recognition (SR) engine.
|Set:||(This property is read-only)|
|Get:||Single = ISpeechPhraseElement.EngineConfidence|
The owning object.
Set: (This property is read-only)
Get: A Single variable that gets the value of the property.
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 it is likely to 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.
Use of the ISpeechPhraseElement is demonstrated in a code example at the end of this section.
