Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class StreamingRecognitionResult.
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.
Num | transcript | message_type | is_final
--- | ----------------------- | ----------------------- | --------
1 | "tube" | TRANSCRIPT | false
2 | "to be a" | TRANSCRIPT | false
3 | "to be" | TRANSCRIPT | false
4 | "to be or not to be" | TRANSCRIPT | true
5 | "that's" | TRANSCRIPT | false
6 | "that is | TRANSCRIPT | false
7 | unset | END_OF_SINGLE_UTTERANCE | unset
8 | " that is the question" | TRANSCRIPT | true
Concatenating the finalized transcripts with is_final set to true,
the complete utterance becomes "to be or not to be that is the question".
