It's keyword boosting / custom vocabulary support on Cartesia's Ink-2 transcription model, so brand names, proper nouns, and unusual spellings get transcribed correctly. Can Cartesia voices speak multiple languages? Yes. As of July 2026, Cartesia voices — including cloned voices — can speak natively in up to 15 languages with locale-specific accents, not just translated text. Are custom cloned voices public by default? No. As of this update, voices you create are private to your organization by default. To use one on a third-party platform, you need to explicitly share it via the API or the "My Voices" tab in the playground. Which Cartesia TTS models are being deprecated? Sonic 2, Sonic Turbo, and the October 2025 version of Sonic 3 are being sunset after October 20, 2026. Cartesia recommends migrating to Sonic 3.5. Can I manage my organization's users via the Cartesia API? Yes. The API now supports listing users, listing and creating invites, and removing users — this requires an admin API key.
