In a recent demonstration, AssemblyAI showed how quickly a live voice agent can be built using Claude Code and the AssemblyAI Voice Agent API. The entire process, from concept to deployment, took just minutes.
The build-along video walks through several key phases:
- Prototype in 20 Minutes: A working prototype was assembled rapidly.
- MCP Server Setup: The AssemblyAI MCP server is installed to enable tool calling.
- Prompt-Driven Development: Claude Code is prompted to generate both frontend and backend code automatically.
- Deployment to Railway: The app is deployed live with a few clicks.
- Issue Resolution: Deployment and authentication issues are fixed on the fly.
- Live Demo: The resulting voice agent is demonstrated, with capabilities for custom voices and tool calling.
The project highlights how AI-powered coding tools can streamline the creation of voice-enabled applications, reducing development time from days to minutes. The approach combines natural language prompting with cloud deployment, making it accessible even to developers with limited experience in voice technology.
