Overview

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 | trueConcatenating the finalized transcripts withis_final` set to true, the complete utterance becomes "to be or not to be that is the question".

Instance Attribute Details

#confidence ⇒ Float

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. Corresponds to the JSON property confidence

Returns:

  • (Float)

end

#dtmf_digits ⇒ Google::Apis::DialogflowV2::GoogleCloudDialogflowV2beta1TelephonyDtmfEvents

A wrapper of repeated TelephonyDtmf digits. Corresponds to the JSON property dtmfDigits

Returns:

end

#is_final ⇒ Boolean Also known as: is_final?

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. Corresponds to the JSON property isFinal

Returns:

  • (Boolean)

#language_code ⇒ String

Detected language code for the transcript. Corresponds to the JSON property languageCode

Returns:

  • (String)

#message_type ⇒ String

def message_type
  @message_type
end

#speech_end_offset ⇒ String

Time offset of the end of this Speech recognition result relative to the beginning of the audio. Only populated for message_type = TRANSCRIPT. Corresponds to the JSON property speechEndOffset

Returns:

  • (String)

#speech_word_info ⇒ Array<Google::Apis::DialogflowV2::GoogleCloudDialogflowV2beta1SpeechWordInfo>

Word-specific information for the words recognized by Speech in transcript. Populated if and only if message_type = TRANSCRIPT and [InputAudioConfig. enable_word_info] is set. Corresponds to the JSON property speechWordInfo

Returns:

# File 'lib/google/apis/dialogflow_v2/classes.rb', line 20231

def speech_word_info
  @speech_word_info
end

#stability ⇒ Float

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 TRANSCRIPT results with is_final = false. * Otherwise, the value is in (0.0, 1.0] where 0.0 means completely unstable and 1.0 means completely stable. Corresponds to the JSON property stability

Returns:

  • (Float)
