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.
Example:
-
transcript: “tube”
-
transcript: “to be a”
-
transcript: “to be”
-
transcript: “to be or not to be” is_final: true
-
transcript: “ that’s“
-
transcript: “ that is“
-
message_type:
END_OF_SINGLE_UTTERANCE
-
transcript: “ that is the question“ is_final: true
Only two of the responses contain final results (#4 and #8 indicated by
is_final: true
). Concatenating these generates the full transcript: “to be
or not to be that is the question”.
In each response we populate:
-
for
TRANSCRIPT
:transcript
and possiblyis_final
. -
for
END_OF_SINGLE_UTTERANCE
: onlymessage_type
.
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.
stability: f32
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 withis_final = false
. - Otherwise, the value is in (0.0, 1.0] where 0.0 means completely unstable and 1.0 means completely stable.
speech_word_info: Vec<SpeechWordInfo>
Word-specific information for the words recognized by Speech in
[transcript][google.cloud.dialogflow.cx.v3beta1.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
.
