## What the story says

LiveKit uses Cartesia's Sonic text-to-speech model as the voice for its LiveKit Agents framework, which developers use to build real-time voice and multimodal AI agents. Cartesia is available as an integration for LiveKit Agents, which are deployed for uses such as emergency dispatch, gaming, autonomous vehicles and enterprise solutions.

Summary written by usedby from the source page, in English. The figures are those of Cartesia and LiveKit, not ours.

> LiveKit chose to partner with Cartesia because Sonic, built on State Space Models, a fundamentally new architecture for AI, perfectly aligned with LiveKit’s vision for next-generation AI agents.

> Internet applications weren’t built for how we’ll use computers in the future. Those computers will see, hear, and speak like we do. We’ll interact with them like we do with each other. We designed LiveKit’s Agents framework to make it easy to build applications for this new paradigm. Cartesia—pioneers of the SSM architecture—shared our belief that real-time, multimodal AI models would be at the center of computing, making them the perfect Agents launch partner.
