Voice Interfaces Go Full Duplex
Voice AI moves from turn-taking pipelines to continuous duplex models that own the interaction loop and delegate hard reasoning to larger models in the background, collapsing the separate speech recognition and synthesis vendor stack into a single serving component.

OpenAI detailed GPT-Live, which listens and speaks simultaneously and decides many times per second whether to talk, wait or interrupt, handing hard questions to GPT-5.5 in the background. A frontier lab shipping exactly the architecture the thesis describes — one duplex model owning the interaction loop with a larger model as an asynchronous reasoning backend — is the strongest form of confirmation short of displacement data from speech vendors.
