public ReadOnlyCollection<RecognizedPhrase> Alternates { get; }

Property Value

The collection of alternate recognitions.

Remarks

Alternates are ordered by 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. The phrase with the highest recognition score is the phrase that most likely matches the user's utterance.

A Confidence score is also calculated for each alternate. The confidence score of a given alternate is calculated independently from its recognition score, and indicates the recognition engine's degree of confidence that the given result is a valid alternate. 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 each confidence score is a measure only of a specific alternate???s validity.
