Voice AI depends on the plumbing, too

In an engineering article, OpenAI described changes to its WebRTC stack for voice AI. The work concerns latency, scale, and conversational turn-taking: infrastructure users rarely see directly but experience as interruptions, delays, or smoother exchanges.

A spoken interface is an end-to-end system. It must hear the phrase, interpret the pause, and respond at the right moment. Accelerating a model does little if another stage introduces a long wait. Conversational scenarios provide a better product test than text-generation speed alone.
