In this video, I show you how to build and deploy voice AI agents fast and cheap—without being a developer. Voice agents are trending hard, and people are paying real money for them (I literally found Upwork gigs ranging from $100 to $4,000). The key takeaway: you can build humanlike voice agents using UltraWox, connect them to a real phone number with Twilio, and orchestrate everything inside n8n so your agent can work 24/7. I walk you through UltraWox (5 cents per minute, plus 30 minutes free credit) and why it feels so fast: it’s built for direct speech processing, so you avoid the typical ASR-to-text latency. I show how I structure prompts (identity, style, response guidelines, tasks/goals), how greetings work (who speaks first), and how to add tools like a hangup tool so the agent can end calls and save credits. Then I connect the whole thing in n8n with two workflows: one for outbound calls (agent calls the user using data from Google Sheets) and one for inbound calls (user calls your Twilio number, Twilio hits an n8n webhook, and we return the UltraWox join URL). Finally, I show hosting n8n on Hostinger so your automations run nonstop without cloud limits.
