# Audiblez: Generate audiobooks from e-books

### v4 Now with Graphical interface, CUDA support, and many languages!

Audiblez generates `.m4b` audiobooks from regular `.epub` e-books,
using Kokoro's high-quality speech synthesis.
[Kokoro-82M](https://huggingface.co/hexgrad/Kokoro-82M) is a recently published text-to-speech model with just 82M params and very natural sounding output.
It's released under Apache licence and it was trained on < 100 hours of audio.
It currently supports these languages: 🇺🇸 🇬🇧 🇪🇸 🇫🇷 🇮🇳 🇮🇹 🇯🇵 🇧🇷 🇨🇳
On a Google Colab's T4 GPU via Cuda, **it takes about 5 minutes to convert "Animal's Farm" by Orwell** (which is about 160,000 characters) to audiobook, at a rate of about 600 characters per second.
On my M2 MacBook Pro, on CPU, it takes about 1 hour, at a rate of about 60 characters per second.
## How to install the Command Line tool
If you have Python 3 on your computer, you can install it with pip.
You also need `espeak-ng` and `ffmpeg` installed on your machine:
```bash
sudo apt install ffmpeg espeak-ng # on Ubuntu/Debian 🐧
pip install audiblez
```
```bash
brew install ffmpeg espeak-ng # on Mac 🍏
pip install audiblez
```
Then you can convert an .epub directly with:
```
audiblez book.epub -v af_sky
```
It will first create a bunch of `book_chapter_1.wav`, `book_chapter_2.wav`, etc. files in the same directory,
and at the end it will produce a `book.m4b` file with the whole book you can listen with VLC or any
audiobook player.
It will only produce the `.m4b` file if you have `ffmpeg` installed on your machine.
## How to run the GUI
The GUI is a simple graphical interface to use audiblez.
You need some extra dependencies to run the GUI:
```
sudo apt install ffmpeg espeak-ng
sudo apt install libgtk-3-dev # just for Ubuntu/Debian 🐧, Windows/Mac don't need this
pip install audiblez pillow wxpython
```
Then you can run the GUI with:
```
audiblez-ui
```
## How to run on Windows
After many trials, on Windows we recommend to install audiblez in a Python venv:
1. Open a Windows terminal
2. Create anew folder: `mkdir audiblez`
3. Enter the folder: `cd audiblez`
4. Create a venv: `python -m venv venv`
5. Activate the venv: `.\venv\Scripts\Activate.ps1`
6. Install the dependencies: `pip install audiblez pillow wxpython`
7. Now you can run `audiblez` or `audiblez-ui`
8. For Cuda support, you need to install Pytorch accordingly: https://pytorch.org/get-started/locally/
## Speed
By default the audio is generated using a normal speed, but you can make it up to twice slower or faster by specifying a speed argument between 0.5 to 2.0:
```
audiblez book.epub -v af_sky -s 1.5
```
## Supported Voices
Use `-v` option to specify the voice to use. Available voices are listed here.
The first letter is the language code and the second is the gender of the speaker e.g. `im_nicola` is an italian male voice.

## How to run on GPU
By default, audiblez runs on CPU. If you pass the option `--cuda` it will try to use the Cuda device via Torch.
Check out this example: [Audiblez running on a Google Colab Notebook with Cuda ](https://colab.research.google.com/drive/164PQLowogprWQpRjKk33e-8IORAvqXKI?usp=sharing]).
We don't currently support Apple Silicon, as there is not yet a Kokoro implementation in MLX. As soon as it will be available, we will support it.
## Manually pick chapters to convert
Sometimes you want to manually select which chapters/sections in the e-book to read out loud.
To do so, you can use `--pick` to interactively choose the chapters to convert (without running the GUI).
## Help page
For all the options available, you can check the help page `audiblez --help`:
```
usage: audiblez [-h] [-v VOICE] [-p] [-s SPEED] [-c] [-o FOLDER] epub_file_path
positional arguments:
epub_file_path Path to the epub file
options:
-h, --help show this help message and exit
-v VOICE, --voice VOICE
Choose narrating voice: a, b, e, f, h, i, j, p, z
-p, --pick Interactively select which chapters to read in the audiobook
-s SPEED, --speed SPEED
Set speed from 0.5 to 2.0
-c, --cuda Use GPU via Cuda in Torch if available
-o FOLDER, --output FOLDER
Output folder for the audiobook and temporary files
example:
audiblez book.epub -l en-us -v af_sky
to use the GUI, run:
audiblez-ui
```
