Generate speech with a voice cloned into Wireflow's Fish Audio account.
Fish TTS
Badge: New
Node type: audio:fish_tts
Category: audio
Description
Generate speech with a voice cloned into Wireflow's Fish Audio account. Wire the Fish Voice Clone node into voice_id, or pick one of your saved voices in the sidebar.
Runs on Wireflow's Fish account, so there is no API key to bring. Output is a hosted .wav (44.1 kHz) that plays inline on the node.
Pricing
- Cost: 3 credits per run, flat, regardless of how long the text is.
Canvas ports
These appear as port handles on the left side of the node.
| ID | Label | Details |
|---|---|---|
text |
Text | TEXT (required) |
voice_id |
Voice | TEXT (required). Fish reference_id. Connect the Fish Voice Clone node, or pick a cloned voice in the sidebar. |
Sidebar config
The Voice field doubles as a config control when nothing is wired into the port:
- A dropdown of voices you cloned in Wireflow (Fish Voice Clone node).
- Paste a Fish voice ID for a model you already made on fish.audio. That only works if the model's visibility is public or unlisted. A private model in your own account is not reachable with Wireflow's key. Pasted IDs are checked as you type.
Outputs

Limits
- 1,500 bytes of text per run. That is 1,500 characters of plain English, but non-Latin scripts (Chinese, Japanese, Korean, Arabic) and emoji use up to 3-4 bytes per character, so roughly 500 characters of Chinese hits the same ceiling. Fish charges by UTF-8 byte, which is why the limit is counted that way.
- Longer scripts should be split across several TTS nodes (or driven by an iterator) and the audio joined. Over-limit runs are refused before anything is charged.
- You can only use your own cloned voices, voices shared publicly, or an external Fish voice that is public/unlisted.
Notes
- Voice quality tracks the sample, not the settings. A clean 15s reference beats a noisy 2 minutes.
- "Voice is private to another Fish Audio account". The pasted ID is not visible to Wireflow's key. Clone the voice here, or flip it to unlisted on fish.audio.
- "Fish API wallet is out of funds". That is on us, not your balance. Your credits are refunded. Ping support.
