Turn Detector v1.0 ships; voice deadlock fixed

Introducing LiveKit Turn Detector v1.0

Determining when the agent should respond is a delicate balance: responding too early can interrupt the user, while responding too late introduces unnecessary latency and awkward silence. We solve this with our state-of-the-art turn detector, which leverages both audio and text semantics to identify the optimal moment to respond.

Read more about our turn detector in our blog.
