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: 1. transcript:
“tube” 2. transcript: “to be a” 3. transcript: “to be” 4.
transcript: “to be or not to be” is_final: true 5. transcript: "
that’s" 6. transcript: " that is" 7. message_type:
END_OF_SINGLE_UTTERANCE 8. 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
possibly is_final. - for END_OF_SINGLE_UTTERANCE: only
message_type.
Transcript text representing the words that the user spoke.
Populated if and only if 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.
Word-specific information for the words recognized by Speech
