Voice Activity Detection & Turn-Taking — Silero, Cobra, and the Flush Trick
Every voice agent lives or dies on two decisions: is the user speaking now, and are they done? VAD answers the first. Turn-detection (VAD + silence-hangover + semantic endpoint model) answers the second. Get either wrong and your assistant either cuts users off or never shuts up.
