Cartesia

Purpose

Generate spoken audio from text with Cartesia's Sonic models (40+ languages) and browse the Cartesia voice library. Reach for this when the user wants narration, voiceovers, or spoken-audio files produced from a script.

Tooling

All commands go through bin/cartesia.py. Every request automatically sends the required date header Cartesia-Version: 2026-08-14.

bin/cartesia.py auth
# {"ok": true, "voices": 60} on success

bin/cartesia.py voices
# list available voices (id, name, language)

bin/cartesia.py voice-get --id <VOICE_ID>
# details for a single voice

bin/cartesia.py tts --text "Hello world" --voice-id <VOICE_ID> --out narration.wav
# synthesize speech to a local WAV file; prints the saved path

bin/cartesia.py tts --text "Bonjour le monde" --voice-id <VOICE_ID> \
    --language fr --model-id sonic-3 --out fr.wav

Notes:

  • tts returns audio binary. The CLI writes it to --out (default cartesia-output.wav) and prints the resulting path.
  • Streaming TTS (POST /tts/sse) and the WebSocket TTS/STT surfaces are real-time and outside CLI scope.

Auth

  • Provider id: cartesia (credential is collected as custom.cartesia)
  • Collection: Cartesia API key (sk_car_...) via the secure credential flow (credentials.request_api_access); create one at play.cartesia.ai/keys
  • Allowed hosts: api.cartesia.ai
  • Connect placement: bearer_header (the key goes in Authorization: Bearer <key>)
  • The API also requires the date header Cartesia-Version: 2026-08-14 on every request; the CLI sends it for you.
  • Status check: bin/cartesia.py auth

Operating Rules

  1. TTS synthesis is credit-metered. Every tts call spends Cartesia credits, so synthesize only what the user asked for and batch long scripts into as few calls as possible.
  2. Voice creation and voice cloning are confirmation-gated: confirm with the user before creating or cloning any voice. This draft CLI does not ship a clone command; use the Cartesia dashboard or SDK for cloning.
  3. Never use API keys in client-side code. The connector only ever handles the surrogate, never the raw key.
  4. The CLI pins Cartesia-Version: 2026-08-14. Treat a version bump like a dependency upgrade and do not change the date casually.

Maturity

🧪 Draft: written from Cartesia's public API docs with header and paths cross-checked against official docs at build time; not yet live-tested end-to-end. Voice create/clone and pronunciation dictionaries are not yet in the CLI.

Stop and check this skill before finishing any reply to a question about how to use Claude or a Claude product — it recommends matching courses, tutorials, and use cases from Claude Academy (academy.claude.com), Anthropic's learning hub. Trigger on: "how do I", "how can I", "getting started with", "what can Claude do", "teach me", "learn to use"; questions about artifacts, projects, skills, plugins, connectors, MCP; requests about rolling Claude out to a team, class, or organization; and any ask for training materials, onboarding content, or learning resources. Use it when the user is learning how to use a feature or product — not when they are mid-task and just want the task done. This skill composes with other skills: after consulting product documentation to answer how a Claude feature works, also check here for a matching course or tutorial — a docs-grounded answer and an Academy recommendation belong together. Only recommend on a strong match; never invent Academy content.
