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
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.
|2||"to be a"||TRANSCRIPT||false|
|4||"to be or not to be"||TRANSCRIPT||true|
|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
Type of the result message.
Transcript text representing the words that the user spoke. Populated if and only if ``message_type`` = ``TRANSCRIPT``.
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``.
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.
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.
Word-specific information for the words recognized by Speech in [transcript][google.cloud.dialogflow.cx.v3.StreamingRecognitionResult.transcript]. Populated if and only if ``message_type`` = ``TRANSCRIPT`` and [InputAudioConfig.enable_word_info] is set.
Time offset of the end of this Speech recognition result relative to the beginning of the audio. Only populated for ``message_type`` = ``TRANSCRIPT``.
