Cartesia integration

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.

Before you build

Three things worth knowing.

Filter at the trigger

Each workflow step uses 1 credit. Put a filter right after the trigger: events that don't match stop there and only use credits for the steps that already ran.

Authorize once, reuse anywhere

Connect Cartesia once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.

No JSON to read

Every Cartesia field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.

Cartesia actions execute synchronously inside your workflow. TinyCommand waits for Cartesia's API to confirm before continuing to the next step, so downstream nodes can rely on the result.
Do I need to write code to use Cartesia with TinyCommand?
No. Every Cartesia trigger and action is fully configurable from the visual workflow builder. For edge cases that aren't covered, drop in a custom HTTP node and call any Cartesia API endpoint directly.
