FAQ

Questions about Cartesia Sonic TTS.

What does the Cartesia Sonic TTS action do in Cartesia?

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.

What inputs does Cartesia Sonic TTS require?

Required: Text, Voice ID. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Cartesia returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Cartesia Sonic TTS support batch operations?

Yes. Run Cartesia Sonic TTS inside a Loop node to process arrays. Tiny Command handles Cartesia's rate limits automatically so you don't have to throttle manually.
