Building a Real-Time AI Voice Agent with OpenAI Realtime API and Next.js

Short summary

Comprehensive guide to building production-grade real-time voice AI agents using OpenAI's Realtime API and Next.js. Covers architecture patterns including audio streaming via WebSocket, low-latency model responses, function calling for business actions, session memory management, and production scaling. Includes code examples and real-world use cases for customer support, sales automation, and e-commerce.

• •Real-time voice AI architecture: continuous audio streaming → AI model → function calling → business APIs
• •Key production considerations: latency optimization (<800ms), session memory compression, horizontal scaling, security encryption
• •Use cases: customer support automation, e-commerce voice discovery, hospitality bookings, sales interactions
