Why it matters

OpenAI shipped a new capability layer that enables low-latency voice interactions at scale. This moves speech AI from research/demo territory into developer tooling, directly competing with Twilio, Vonage, and custom speech stacks — and raising the bar for what 'conversational AI' means in production.

The key facts
