About Cartesia
Cartesia builds speech models designed for speed, which matters when an AI agent has to talk back to someone without awkward pauses. Its Sonic model produces voice with very low latency, so conversations feel natural.
The platform offers text to speech, voice cloning and tools for building voice agents, plus an API and SDKs for developers. Control over emotion, speed and accents helps match a brand's voice.
