Overview
Cartesia is an AI audio and voice intelligence company that powers conversational AI agents and interactive applications with ultra-low-latency, hyper-realistic voice synthesis. Its flagship State Space Model (SSM) architecture, Sonic, delivers human-like voice generation with sub-90ms time-to-first-audio latency. While traditional transformer-based text-to-speech models struggle with high latency and compute overhead, Cartesia's lightweight SSM architecture allows developers to build fluid, conversational voice bots that feel instantaneous and natural, without awkward pauses. Cartesia is used by developers, contact centers, game studios, and AI agent builders across the world to power real-time phone assistants, gaming NPCs, live transcription translation, and voice-enabled enterprise interfaces.
Cartesia's Sonic engine is built on state space foundation models designed specifically for continuous streaming audio. It supports multilingual voice cloning from a 5-second sample, fine-grained emotional control (whisper, excitement, professional demeanor), and dynamic pacing adjustments. Developers can integrate Cartesia via WebSocket and REST APIs, Python and TypeScript SDKs, and WebRTC streaming for mobile and browser applications. The platform handles concurrent high-throughput workloads with strict SLA guarantees.
