Property Value

The confidence value for the recognized result.

Remarks

The confidence value ranges from 0.0 (lowest confidence) to 1.0 (highest confidence).

The confidence score of a given result or alternate indicates the recognition engine's degree of confidence that the given result is a valid alternate. The confidence score is calculated independently from the recognition score. The recognition score of a given phrase indicates the probability that the phrase, when compared to all of the possible alternates, matches the user's utterance.

RecognitionResult.Alternates are ordered by recognition score, and the phrase with the highest recognition score is the phrase that most likely matches the user's utterance. Confidence scores are typically, although not necessarily, lower for each successive alternate. Confidence scores should be evaluated individually for each alternate without reference to the confidence scores of other alternates because they are a measure only of a specific alternate???s validity.
