Building an AI Voice Agent That Can Search the Web With Cartesia and Bright Data

Cartesia is a developer-first platform designed for building real-time AI voice agents, featuring low-latency speech models and a comprehensive agent development stack to streamline the transition from concept to a production-ready voice agent. It incorporates two in-house models: Sonic, a text-to-speech model offering expressive speech across multiple languages, and Ink, a speech-to-text model capable of handling various accents and noise. However, voice agents need real-time data access to overcome the limitations of static knowledge within Large Language Models (LLMs), which is where integrations like Bright Data come into play. By connecting Cartesia agents to Bright Data, developers can enhance these agents with web search and data extraction capabilities using tools like the SERP API and Web Unlocker API, allowing for more accurate, context-aware, and actionable responses. This integration supports dynamic, real-time information retrieval, vital for maintaining the relevance and trustworthiness of AI voice agents. The step-by-step guide provided demonstrates how to set up a Cartesia project, integrate Bright Data services, and develop an AI voice agent capable of delivering news-style reports and engaging in interactive conversations.
