Speech-to-Text provides the latest_short
model for recognizing speech that
consists of single utterances. This may be useful for applications where users
are issuing single voice commands as opposed to long-form monologue or
dictation.
When a recognizer with the latest_short
model is used for a recognition
request, Speech-to-Text will stop performing recognition once it detects
an utterance has finished. Speech-to-Text will return a speech activity
event response with the type END_OF_SINGLE_UTTERANCE
followed by the
transcription results.
Single utterance and StreamingRecognize
In the case where a latest_short
model Recognizer
is selected for a StreamingRecognize
request, Speech-to-Text will close
the stream automatically after the utterance has ended.
With voice activity events
In the case where voice activity events have also been enabled for a StreamingRecognize request, Speech-to-Text will still return speech begin/end voice activity events. Voice activity timeouts for speech begin will still be applied. Voice activity timeouts for speech end will not be applied, since the stream will be closed as soon as the utterance ends.
