Cartesia
Cartesia Sonic ultra-low-latency TTS
Cartesia is the AI lab whose Sonic TTS model delivers some of the lowest-latency speech synthesis in the industry — built on State Space Models (SSM) architecture that's faster than typical transformer TTS. Tiny Command exposes one action, no triggers: Text to Speech (generate audio from text with voice selection, optional emotion controls). The connection uses a Cartesia API key. For voice-agent workflows where user-perceived latency between speech-in and speech-out matters (real-time conversational AI, voice bots, accessibility tools), Cartesia's sub-200ms TTS latency is the differentiator. ElevenLabs and Hume are typically higher quality but slower. Play.ht is comparable speed but different voice characteristics. For "voice agent that doesn't feel laggy", Cartesia is purpose-built.
Do anything Cartesia can do, from a workflow.
Every action accepts dynamic inputs from upstream nodes, whether that's an AI output, a form field, or a search result.
| Action | What it does |
|---|---|
| Cartesia Sonic TTS | Generates audio from text using Cartesia's Sonic model — ultra-low latency (sub-200ms typical), optimised for real-time voice agents. For broadcast-quality narration where peak quality matters more than speed, use ElevenLabs instead. |

Clone any recipe and customize it in one click. Every recipe is fully editable.
Three things worth knowing.
Tiny Command counts a run the moment a trigger fires. Filtering early means only matching events spend your usage budget.
Connect Cartesia once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.
Every Cartesia field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.
