Smart Turn for Streaming STT
Smart Turn for Streaming STT The streaming Speech to Text API now supports Smart Turn end-of-turn detection. When enabled via the smart_turn query parameter, an ML model predicts whether the speaker has finished their thought at silence boundaries — reducing false endpointing during dictation, number sequences, and mid-sentence pauses. Use smart_turn_timeout to set a maximum silence fallback. For more details, see the Smart Turn docs . May 29

Publication boundary
Confidence, importance, and discussion are three different numbers.
Official and first-party repository changes may publish automatically after deterministic validation. Independent sources remain draft until review. Community links are attached as discussion evidence and cannot create an indexable fact by themselves.
