About Fixie.ai

Ultravox.ai, developed by Fixie.ai, is a real-time, speech-native voice AI platform designed to overcome the limitations of traditional voice AI systems. Unlike approaches that convert speech to text, Ultravox.ai processes speech directly, preserving paralinguistic signals like tone and cadence, which are crucial for natural human conversation. This speech-native approach, combined with a fully managed inference stack and dedicated infrastructure, significantly reduces latency, allowing for fast, natural, and scalable voice AI agents. The platform is built for developers and companies looking to integrate advanced voice AI capabilities into their applications. It offers robust APIs, intuitive developer kits for web and mobile, and built-in tools to help build and scale voice agents. Ultravox.ai also provides telephony support for integration with major providers. By focusing on a unified stack for audio intelligence, Ultravox.ai aims to enable the creation of highly performant voice agents that can speak, listen, and interact in real-time, mimicking human communication more effectively than existing solutions.
