StoryVox Pro Features

Everything a Professional
Audiobook Demands

StoryVox Pro is built for authors who want broadcast-quality results without a recording studio, a voice actor, or a cloud subscription.

🎙️

Near ElevenLabs Quality

Powered by Supertonic 3 — one of the most advanced local TTS models available. Natural prosody, expressive delivery, and consistent character that puts it in the same league as premium cloud services, without the monthly bill.

∞

Unlimited Voices

Ten high-quality built-in voices are just the start. Clone any voice from a short audio sample using the included Voice Cloner companion tool. Build a library of narrators for every genre, character, and style — with no per-voice fees.

✈️

Fully Offline

No internet connection. No cloud processing. No usage monitoring. Your manuscripts, your voices, and your audiobooks never leave your computer. Complete creative and commercial privacy.

📚

Professional M4B Export

Export finished audiobooks in M4B format with embedded chapter markers, cover art, author metadata, and custom bitrate — ready for direct distribution, your own website, or platforms that accept AI-generated audio.

🗂️

Project Manager

Work on multiple books simultaneously. Each project stores its own chapters, voice settings, scripts, and export preferences. Switch between projects instantly and pick up exactly where you left off.

🎛️

Fine-Tuned Control

Speed, pacing gap, and quality controls let you dial in exactly the narration style you want. Preview any chapter live, edit the script in-app, and regenerate individual sentences without re-doing the whole chapter.

Voices

10 Built-In. Unlimited Custom.

StoryVox Pro ships with ten premium voices powered by Supertonic 3. Male and female, multiple character styles — ready to narrate the moment you install.

M1 — Male 1 M2 — Male 2 M3 — Male 3 M4 — Male 4 M5 — Male 5 F1 — Female 1 F2 — Female 2 F3 — Female 3 F4 — Female 4 F5 — Female 5 + Your Custom Voices + Cloned Narrators

Unlimited Custom Voices

Clone any voice from a short audio sample. Your custom voices are saved to your Documents folder and available instantly in every project. No limits, no fees, no approval process.

Why Unlimited Voices Matter

ElevenLabs charges per character. Eleven characters in a 300-page audiobook costs real money — month after month. A single novel can run $80–$150 in API fees at mid-tier pricing.

StoryVox Pro is a one-time purchase. Your tenth book costs the same as your first: $0 per word, $0 per minute, $0 per voice.

One purchase. Unlimited audiobooks. Forever.

Language Support

31 Languages. One Engine.

StoryVox Pro is powered by Supertonic 3 — a multilingual AI engine that narrates naturally in 31 languages with no additional downloads, no separate models, and no extra cost.

English Spanish French German Japanese Korean Arabic Hindi Portuguese Italian Dutch Russian Polish Swedish Turkish Vietnamese Ukrainian Romanian Greek Czech Hungarian Finnish Danish Slovak Bulgarian Croatian Slovenian Lithuanian Latvian Estonian Indonesian

Language is selected per project. Mix languages across chapters — one book, multiple narration languages, all from the same set of voices.

Companion Tool

Voice Cloner — Free for StoryVox Pro Owners

Create a custom AI narrator from a short audio clip. Train on your own voice, a character voice, or any clean recording you have rights to use.

Included Free with StoryVox Pro

Your Voice.
Your Audiobook.

Voice Cloner uses a local gradient descent training pipeline to learn the vocal characteristics of any clean audio sample — typically 10–30 seconds is enough for a solid clone.

The resulting voice profile installs directly into StoryVox Pro. From that point on, every chapter you generate sounds like the source voice — at any length, for any book, with zero additional cost.

  • Train from a short WAV or MP3 clip
  • GPU accelerated — typical training under 40 minutes
  • Saves voice profile to your Documents folder
  • Import into StoryVox Pro with one click
  • No cloud upload — training runs entirely on your PC
  • Unlimited voices — clone as many as you need
  • Compatible with StoryVox Pro's full feature set

Voice Cloner is distributed free to verified StoryVox Pro owners.

Voice Cloner Requirements

For training: NVIDIA GPU with 8 GB or more VRAM (CUDA-compatible). Training on cards with less VRAM or on CPU is not supported.
For playback: Any Windows PC — cloned voices synthesize in StoryVox Pro on CPU with no GPU required.

How It Works

Manuscript to Audiobook
in Five Steps

1

Create a Project

Start a new project and name your audiobook. StoryVox Pro keeps each book's settings, scripts, and voices organized separately.

2

Import Your Text

Drop in a .txt file or import an entire folder. Chapters are detected automatically and can be split, merged, and renamed.

3

Choose Your Voice

Select from the ten built-in voices or import a custom cloned narrator. Adjust speed, pacing, and quality. Preview any chapter live.

4

Generate

StoryVox Pro synthesizes each chapter sentence by sentence, building broadcast-quality audio with natural pacing throughout.

5

Export M4B

Assemble your chapters into a finished M4B audiobook with cover art, chapter markers, and embedded metadata — ready for distribution.
