The Text2Audio Studio — importing chapter files and choosing a narrator voice

A Complete Audiobook Studio That Runs on Your Own Computer

Drop in your manuscript (.txt or Markdown), pick a narrator, and get a mastered .m4b audiobook with chapter markers — the kind that plays in Apple Books, Smart AudioBook Player, and BookPlayer with full chapter navigation.

Book → Audiobook

Text or Markdown in, chaptered .m4b out. Each chapter file's first heading becomes its chapter title, so listeners can skip and resume just like a commercial audiobook.

Mastered Audio

128 kbps AAC, loudness-normalised to around −19 LUFS, high-pass filtered, with natural sentence and paragraph pacing. Re-master any book instantly without re-synthesising.

Reads Text Correctly

Expands numbers and abbreviations, and an editable pronunciation dictionary fixes tricky names and places so the narration doesn't stumble.

Voice Cloning (optional)

Upload 10–30 seconds of clean speech and narrate in that voice, powered by F5-TTS. The fast default voice stays available; cloning runs isolated so it never slows the rest down.

Studio Web UI

Drag-and-drop multi-file import, a voice gallery, live per-chapter progress, a built-in chapter player, and a library of everything you've made.

100% Local & Private

Everything runs offline on your own GPU using open models. Your manuscript and audio never leave your machine — nothing is uploaded anywhere.

One Clean Studio, Three Simple Steps

Choose or clone a voice, generate with live progress, then listen and manage your library — all in the browser.

Built So Non-Technical People Can Use It Too

On Windows you can be up and running in three steps — no command line at any point.

1

Download

Grab the project as a ZIP from GitHub and unzip it anywhere — your Desktop is fine.

2

Double-click Install

Run Install Text2Audio.bat. It sets everything up for you — Python, the app, ffmpeg, and the speech tools — and adds a Desktop shortcut.

3

Double-click Start

Run Start Text2Audio. Your browser opens the Studio and you're making audiobooks. The voice model downloads once, then it's fully offline.

Getting past the Windows SmartScreen prompt: click More info, then Run anyway
The one manual moment: if Windows shows a SmartScreen prompt for the unsigned installer, click More info → Run anyway.

Prefer a terminal? Technical users on any OS can pip install git+https://github.com/mooja77/Text2Audio and run text2audio. Full instructions are in the project's INSTALL guide.

Audiobooks Shouldn't Cost a Subscription or Your Privacy

Commercial AI narration tools charge per word, lock your audio behind an account, and send your manuscript to someone else's servers. Text2Audio is our answer: a proper audiobook studio that's free, private, and yours to keep.

Free Forever

MIT-licensed and open source. No subscription, no per-word billing, no upsell. Use it for as many books as you like.

Private by Design

It runs on your own hardware. Your words and the finished audio never touch the internet.

Yours to Inspect

The full source is on GitHub. Read it, fork it, improve it — contributions are welcome.

Real Audiobook Files

Proper .m4b output with chapter markers, not just a wall of MP3 — it behaves like a book in any audiobook player.
