public sealed class SpeechRecognitionAlternative : IMessage<SpeechRecognitionAlternative>, IEquatable<SpeechRecognitionAlternative>, IDeepCloneable<SpeechRecognitionAlternative>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Speech v1 API class SpeechRecognitionAlternative.
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 of a non-streaming
result or, of a streaming result where is_final=true.
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.
Transcript text representing the words that the user spoke.
In languages that use spaces to separate words, the transcript might have a
leading space if it isn't the first result. You can concatenate each result
to obtain the full transcript without using a separator.
A list of word-specific information for each recognized word.
Note: When enable_speaker_diarization is true, you will see all the words
from the beginning of the audio.
