Features
Cartesia combines speech synthesis, transcription and voice agents. Monthly plans include credits and agent credit, but telephony and call minutes are billed separately. Documented minutes are model estimates, not a blanket output promise. Inputs and outputs may serve model training by terms; a future opt-out and Enterprise ZDR are narrower.
- TTS, STT and managed voice agents with separate consumption types
- Zero Data Retention only for Enterprise TTS/STT
