Provides information to the recognizer that specifies how to process the
request.
Optional If false or omitted, the recognizer will
perform continuous recognition (continuing to wait for and
process audio even if the user pauses speaking) until the
client closes the input stream (gRPC API) or until the maximum
time limit has been reached. May return multiple
StreamingRecognitionResult\ s with the is_final flag
set to true. If true, the recognizer will detect a
single spoken utterance. When it detects that the user has
paused or stopped speaking, it will return an
END_OF_SINGLE_UTTERANCE event and cease recognition. It
will return no more than one StreamingRecognitionResult
with the is_final flag set to true.
