Ultravox

Ultravox is the open-weight Speech Language Model (SLM) enabling direct, real-time, and natural conversational AI for enterprise agents.

This is next-gen voice AI. Ultravox functions as an open-weight Speech Language Model (SLM), engineered to understand speech directly—it bypasses the legacy speech-to-text component system entirely. This architecture delivers significantly faster, more consistent response times, which is critical for natural, human-like dialogue. Developed by Fixie.ai, the platform is built for enterprise-grade conversational agents, supporting high-volume, low-latency communication stacks. Deploy Ultravox to power dynamic, real-time interactions across customer support, collaboration, and R&D applications.
