Expand description
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”.
Fields
message_type: i32
Type of the result message.
transcript: String
Transcript text representing the words that the user spoke.
Populated if and only if message_type
= TRANSCRIPT
.
is_final: bool
If false
, the StreamingRecognitionResult
represents an
interim result that may change. If true
, the recognizer will not return
any further hypotheses about this piece of the audio. May only be populated
for message_type
= TRANSCRIPT
.
confidence: f32
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.
speech_word_info: Vec<SpeechWordInfo>
Word-specific information for the words recognized by Speech in
[transcript][google.cloud.dialogflow.v2.StreamingRecognitionResult.transcript]. Populated if and only if message_type
= TRANSCRIPT
and
[InputAudioConfig.enable_word_info] is set.
speech_end_offset: Option<Duration>
Time offset of the end of this Speech recognition result relative to the
beginning of the audio. Only populated for message_type
= TRANSCRIPT
.
language_code: String
Detected language code for the transcript.
Implementations

, or the default if the field is set to an invalid enum value.
