Reference documentation and code samples for the Cloud Speech-to-Text v2 API class StreamingRecognitionResult.
A streaming speech recognition result corresponding to a portion of the audio
that is currently being processed.
public RepeatedField<SpeechRecognitionAlternative> Alternatives { get; }
May contain one or more recognition hypotheses. These alternatives are
ordered in terms of accuracy, with the top (first) alternative being the
most probable, as ranked by the recognizer.
For multi-channel audio, this is the channel number corresponding to the
recognized result for the audio from that channel.
For
audio_channel_count = N, its output values can range from 1 to N.
If false, this
[StreamingRecognitionResult][google.cloud.speech.v2.StreamingRecognitionResult]
represents an interim result that may change. If true, this is the final
time the speech service will return this particular
[StreamingRecognitionResult][google.cloud.speech.v2.StreamingRecognitionResult],
the recognizer will not return any further hypotheses for this portion of
the transcript and corresponding audio.
Output only. The BCP-47
language tag of the language in this result. This language code was
detected to have the most likelihood of being spoken in the audio.
An estimate of the likelihood that the recognizer will not change its guess
about this interim result. Values range from 0.0 (completely unstable)
to 1.0 (completely stable). This field is only provided for interim results
([is_final][google.cloud.speech.v2.StreamingRecognitionResult.is_final]=false).
The default of 0.0 is a sentinel value indicating stability was not set.
