Building a voice agent with a coding agent: why this approach beats a visual builder

AssemblyAI's Voice Agent API is designed to work with coding agents rather than traditional visual interfaces, offering greater flexibility and capability for building voice agents. Unlike visual builders that use point-and-click methods to configure agents, coding agents allow users to describe desired functionalities in plain language, which the coding agent then translates into code. This approach eliminates the constraints imposed by predefined interface fields and allows for more complex, customizable solutions. AssemblyAI provides a detailed setup prompt that guides the coding agent through the process of building a voice agent, enabling users to create a fully functional project without needing extensive coding knowledge. The API integrates with popular coding agents like Claude Code, Cursor, and GitHub Copilot, making it accessible to non-developers who are comfortable with basic command-line operations. By allowing users to own and modify the code directly, this method provides superior adaptability and scalability compared to visual builders, which are limited by their design interfaces.
