Voice AI crossed the line from demo to deployment in the last 18 months. ElevenLabs voices are indistinguishable from humans. Vapi and Retell turned voice infrastructure into a Stripe-style API. 11x's Julian, Sierra's agents, and Decagon's voicebots are taking real customer calls today. The category is forming so fast that the vocabulary itself isn't settled — voice agents, conversational AI, voice-native, agentic voice all describe slightly different things.
This is the curation we wish existed. Platforms shipping in production, not demos. Newsletters that publish original benchmarks on latency, voice quality, and reliability. Communities where builders trade what is working at the edge. Updated quarterly as the category settles.
