Cartesia Sonic
Cartesia Sonic 3 is a streaming text-to-speech (TTS) model that converts written text into ultra-realistic, expressive speech with exceptionally low latency, typically starting audio in about 90 milliseconds. It acts as the "vocal cords" for AI agents to enable fluid, natural voice conversations with human-like emotion, tone, and even laughter.
