About Cartesia Sonic
Cartesia Sonic converts text into streamed speech for voice applications. Its product documentation describes voice controls and custom pronunciation dictionaries for domain terms. Sonic is the speech-output layer; it is distinct from Cartesia’s managed agent product and does not by itself define a complete conversational application.
