This ComfyUI workflow turns written scripts into expressive speech using ElevenLabs’ Eleven v4 model. It’s designed around two clear paths: use a preset voice from your ElevenLabs library or instantly clone a voice from an audio sample. The core generation happens in the ElevenLabsTextToSpeech node, which reads your script (written in a Note/MarkdownNote) and applies performance directions you embed as inline tags like [whispers], [excited], [laughs], [sighs], [sarcastic], and [crying]. SaveAudioAdvanced then writes a single audio file to disk.
Technically, Option 1 (Use Preset Voice) routes a selection from ElevenLabsVoiceSelector into ElevenLabsTextToSpeech along with your script and the Eleven v4 model choice. Option 2 (Create a Voice Clone) feeds audio from LoadAudio or RecordAudio into ElevenLabsInstantVoiceClone, which returns a temporary voice you can target in the TTS node. Only one option group should be enabled at a time (select the group and press Ctrl-B to un-bypass it). Because Eleven v4 treats the prompt as a performance script, the workflow lets you direct tone and delivery directly in text while keeping the node graph compact and easy to iterate for narration, audiobooks, and character voiceovers.
API
Usa este flujo de trabajo desde código
Cada flujo de trabajo de Comfy es un grafo JSON. El siguiente payload es este flujo de trabajo, exactamente como lo ejecuta ComfyUI: descárgalo desde la URL, guárdalo en control de versiones o cárgalo en ComfyUI y ejecútalo nodo por nodo.
Ejecuta desde TypeScript o Python con el Comfy SDK. El mismo código funciona en Comfy Cloud o en un ComfyUI propio: solo cambia la URL base.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");El SDK utiliza un flujo de trabajo en formato API: abre este flujo de trabajo en ComfyUI y usa Archivo → Exportar flujo de trabajo (API).
El acceso a la API de Comfy Cloud requiere un plan con clave API.
