public sealed class StreamingRecognitionResult : IMessage<StreamingRecognitionResult>, IEquatable<StreamingRecognitionResult>, IDeepCloneable<StreamingRecognitionResult>, IBufferMessage, IMessageReference documentation and code samples for the Google Cloud Dialogflow v2beta1 API 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".

Properties
Confidence
public float Confidence { get; set; }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.

DtmfDigits
public TelephonyDtmfEvents DtmfDigits { get; set; }DTMF digits. Populated if and only if message_type = DTMF_DIGITS.

IsFinal
public bool IsFinal { get; set; }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.

LanguageCode
public string LanguageCode { get; set; }Detected language code for the transcript.

MessageType
public StreamingRecognitionResult.Types.MessageType MessageType { get; set; }Type of the result message.

SpeechEndOffset
public Duration SpeechEndOffset { get; set; }Time offset of the end of this Speech recognition result relative to the
beginning of the audio. Only populated for message_type = TRANSCRIPT.
| Property Value | |

SpeechWordInfo
public RepeatedField<SpeechWordInfo> SpeechWordInfo { get; }Word-specific information for the words recognized by Speech in
[transcript][google.cloud.dialogflow.v2beta1.StreamingRecognitionResult.transcript].
Populated if and only if message_type = TRANSCRIPT and
[InputAudioConfig.enable_word_info] is set.

Stability
public float Stability { get; set; }An estimate of the likelihood that the speech recognizer will not change its guess about this interim recognition result:
- If the value is unspecified or 0.0, Dialogflow didn't compute the
stability. In particular, Dialogflow will only provide stability for
TRANSCRIPTresults withis_final = false. - Otherwise, the value is in (0.0, 1.0] where 0.0 means completely unstable and 1.0 means completely stable.
