# Audiblez: Generate  audiobooks from e-books

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

![Audiblez GUI on MacOSX](./imgs/mac.png)

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
```
