Audiobook Narrator ElevenLabs TTS API

Overview

The Audiobook Narrator ElevenLabs TTS API is a production-ready Pixelflow workflow that converts long-form text into natural, expressive narration audio. Powered by ElevenLabs' latest eleven_v3 model, this workflow delivers studio-quality speech synthesis optimized for audiobooks, articles, podcasts, and e-learning content.

Unlike generic text-to-speech, this workflow is tuned for sustained narration: stability is set high to keep the voice consistent across thousands of words, style is kept minimal to avoid over-expressive delivery, and speed is slightly reduced to match the measured pace of professional audiobook recordings.

The workflow accepts any ElevenLabs voice ID, giving you full flexibility to use your own cloned voice, a licensed voice from the ElevenLabs marketplace, or any of the thousands of community voices.

How It Works

The workflow consists of four nodes connected in sequence:

1. •Text Input node -- accepts the long-form text to be narrated. This becomes the text parameter in the API request body.
2. •Voice ID Input node -- accepts the ElevenLabs voice ID string. Pass any valid voice ID to control whose voice narrates the content. This becomes the voice_id parameter.
3. •ElevenLabs Text To Speech node -- calls the ElevenLabs API with the eleven_v3 model. Fixed parameters: stability=0.9, style=0.05, speed=0.92. The model ID and stability settings ensure consistent, natural narration even for very long passages.
4. •Audio Output node -- returns the generated audio as the audio field in the API response.

Customization Guide

The following parameters can be adjusted directly in the workflow editor:

• •Voice ID: Change the Voice ID input node's default value to pre-select any ElevenLabs voice. Useful for single-voice deployments where callers do not need to specify a voice.
• •Speed: Modify the speed parameter (0.25 to 4.0) to speed up or slow down narration. The current value of 0.92 is ideal for audiobooks; increase to 1.0 for general narration.
• •Stability: Currently 0.9 for highly consistent output. Lower this (e.g. 0.5) if you want more expressive, variable delivery.
• •Style: Currently 0.05 (near-neutral). Increase up to 1.0 to add more character and expressiveness to the voice.
• •Model ID: Switch from eleven_v3 to eleven_multilingual_v2 for multilingual narration support.
