Audio Generation node

Audio Generation node card

The Audio Generation node synthesizes speech audio from text (text-to-speech) using a speech model.

Handles

HandlePurpose
promptThe text to speak (required)

Configuration

  • Model — the speech model (e.g. openai/tts-1).
  • Voice — the voice to use.
  • Output format — audio format (e.g. mp3).
  • Instructions — extra style guidance.
  • Speed — playback speed.
  • Language — the spoken language, when the model has such a lever.

Not every model honors every field. Fish Audio, for example, infers the language from the text and the chosen voice and has no language parameter at all — so for German audio the upstream Prompt or Agent node has to produce German text. Whenever a provider drops a setting, the run panel lists it under Ignored settings and the node card shows an “ignored” chip; the run itself still succeeds.

Example

Prompt node → Audio Generation:

prompt: "Welcome to Sobmit — the visual workflow builder for AI agents."
model: openai/tts-1

The generated audio ({ dataUrl, mime }) becomes the payload, rendered as an inline player on the card.

Notes

  • The text is required — the engine fails fast without it.
  • The card shows an inline <audio> player and artifact history.
