Smart Turn v2: faster inference, and 13 new languages for voice AI

We’re releasing a new version of our open source Smart Turn model, with improved inference speed, and support for multiple languages. When used alongside a traditional voice activity detection (VAD) model, Smart Turn accurately detects when a speaker has finished their sentence, making use of semantic and vocal cues. Smart Turn specifically uses the audio input (not just a text transcription) to the voice agent to perform the most accurate possible turn detection. The model outputs a prediction, indicating how likely it is that the user has finished speaking.
