The original 4.5 score is retained; its worksheet is not recorded. This documentation review did not re-score or establish performance.
Overview
Cartesia documents Sonic speech synthesis, Ink recognition and Managed Agents combining speech, a selected LLM, tools and telephony. Voice and language support depend on the selected model. Its overview names Sonic 3.5 while pricing lists 3.6; a single model or latency number is not presented as universal.
Developers can evaluate voice components or a managed conversation stack, budgeting model credits separately from agent minutes and carrier/model costs. Test pronunciation and actions before rollout. The reviewed privacy policy says US users only and not intended outside the US, so international eligibility needs confirmation.
