Sparrow

Sparrow 2 is a turn taking model from Tavus, presented through a live browser demo. Turn taking is the part of a voice conversation that decides who holds the floor, when a pause is a real handoff, and when a short sound such as "mm hm" is only an acknowledgment rather than an interruption. The demo lets a visitor hold a spoken conversation with a Tavus PAL, the vendor's conversational AI persona, while a dashboard shows how Sparrow 2 reads the exchange in real time. The dashboard separates whether the speaker is still talking, acknowledging or cutting in, and counts backchannels, noises and interruptions as they occur. A second panel tracks the room, flagging background noise and other voices so the model can avoid reacting to people who are not part of the conversation. An event log shows the signals the model emits, along with context pushed to the language model. The vendor describes this as moving beyond turn taking to whole scene understanding and states that the model is ranked first on its TurnBench benchmark. The page is aimed at developers building voice or video agents on the Tavus platform who want to hear and inspect the behavior before integrating it. A session runs for five minutes, the microphone is the main input, and the camera is optional. A "Start building" link at the end of the demo leads to the Tavus developer offering. The demo page publishes no pricing. Access to Sparrow 2 for production use is through Tavus, and its plans are not shown on this site.
