Overview
Cartesia is the leading Voice AI foundation model research and development company powering the next generation of Voice AI applications. The team developed a suite of products starting with core speech models and expanding into an end-to-end Voice Agent development platform.
Sonic models are the fastest text-to-speech model for real-time conversations, delivering ultra-realistic voice generation 2-3x faster than alternatives - complete with features for voice cloning, customization, controllability, and more.
Ink models are among the fastest speech-to-text models, optimized for real-time use cases and designed for real-world conversations.
Line brings these two models together into a Voice Agent platform, built with developer experience in mind. The flexible, code-first architecture lets teams connect to existing chat systems, bring in any agentic frameworks, and integrate with any systems.
