cartesia-ai

Integrate Cartesia speech APIs (TTS, STT, voices) in application code or coding-agent workflows. Use when the user asks about Cartesia REST/WebSocket APIs, SDKs, API keys, Sonic TTS, Ink STT, voice IDs, access tokens, or embedding voice in an app. For Cartesia Line deployed agents, CLI deploy, and telephony, use the line-voice-agent skill instead.

Build voice agents with the Cartesia Line SDK. Supports 100+ LLM providers via LiteLLM with tool calling, multi-agent handoffs, and real-time interruption handling.
