double
The confidence level of the result.
Remarks
RawConfidence does not indicate the likelihood that a phrase was correctly recognized. Instead it provides a way to compare the relative accuracy of alternatives returned with the recognition result. For example, a RawConfidence score of 0.8 does not mean that a result is 80% likely to be correct; it means the phrase is more likely than an alternative with a RawConfidence of 0.7.
Do not use RawConfidence to determine whether a result should be discarded. RawConfidence values are unique to each recognition engine and can vary between sessions or devices. Instead, check the Confidence property, which indicates a SpeechRecognitionConfidence of High, Medium, Low or Rejected.
