public final class StreamingRecognitionResult extends GeneratedMessageV3 implements StreamingRecognitionResultOrBuilder
Contains a speech recognition result corresponding to a portion of the audio
that is currently being processed or an indication that this is the end
of the single requested utterance.
While end-user audio is being processed, Dialogflow sends a series of
results. Each result may contain a transcript
value. A transcript
represents a portion of the utterance. While the recognizer is processing
audio, transcript values may be interim values or finalized values.
Once a transcript is finalized, the is_final
value is set to true and
processing continues for the next transcript.
If StreamingDetectIntentRequest.query_input.audio.config.single_utterance
was true, and the recognizer has completed processing audio,
the message_type
value is set to END_OF_SINGLE_UTTERANCE and the
following (last) result contains the last finalized transcript.
The complete end-user utterance is determined by concatenating the
finalized transcript values received for the series of results.
In the following example, single utterance is enabled. In the case where
single utterance is not enabled, result 7 would not occur.

Concatenating the finalized transcripts with
is_final` set to true,
the complete utterance becomes "to be or not to be that is the question".

getConfidence()
public float getConfidence()
The Speech confidence between 0.0 and 1.0 for the current portion of audio.
A higher number indicates an estimated greater likelihood that the
recognized words are correct. The default of 0.0 is a sentinel value
indicating that confidence was not set.
This field is typically only provided if is_final
is true and you should
not rely on it being accurate or even set.
