public sealed class SpeechRecognitionAlternative : IMessage<SpeechRecognitionAlternative>, IEquatable<SpeechRecognitionAlternative>, IDeepCloneable<SpeechRecognitionAlternative>, IBufferMessage, IMessage
Output only. The confidence estimate between 0.0 and 1.0. A higher number
indicates an estimated greater likelihood that the recognized words are
correct. This field is set only for the top alternative.
This field is not guaranteed to be accurate and users should not rely on it
to be always provided.
The default of 0.0 is a sentinel value indicating confidence was not set.
Output only. A list of word-specific information for each recognized word.
