This may be useful for applications where users\nare issuing single voice commands as opposed to long-form monologue or\ndictation.\n\nWhen a recognizer with the `latest_short` model is used for a recognition\nrequest, Speech-to-Text will stop performing recognition once it detects\nan utterance has finished.
