Why Most Voice AI Agents Fail - And How We Built One That Works

2025-06-13

In this post, I show you how we built a production-grade real estate voice assistant that actually handles messy, real-world conversations—interruptions, vague answers, multi-step queries, and more. We break down the full architecture—from voice capture (VAPI) to semantic property search (ChromaDB) to automated scheduling (Google Calendar via n8n)—and explain why we chose each tool. Whether you're a developer, founder, or just curious about real-world AI automation, this is the blueprint for building voice agents that don’t suck.

Agent Architecture and Prompt Engineering for Voice AI

2025-06-30

Learn how we designed a single-agent voice assistant that routes tool calls, shapes responses, and keeps conversations natural — all guided by a carefully crafted system prompt. We’ll break down how the agent communicates with tools like property search and scheduling while maintaining a human-like tone. This post is packed with real code, prompt examples, and architectural decisions that you can adapt to your own AI projects.
