What is it?

ebook2audiobook (E2A) turns EPUB, MOBI, PDF, and many other e-book formats into audio files, with chapter detection for formats like EPUB and MOBI. It runs a web interface through Gradio or a headless command-line mode for batch conversion of a single file or a whole folder.

The project integrates several text-to-speech engines, including XTTSv2, Bark, Fairseq, VITS, Tacotron2, Tortoise, GlowTTS, and YourTTS. Users can clone a voice from their own audio sample, load custom or fine-tuned models, and add SML tags for pauses, breaks, and voice switches. OCR is available for scanned pages.

Output can be exported as m4b, mp3, m4a, flac, wav, and other audio formats. It runs on CPU, NVIDIA CUDA, AMD ROCm, Intel XPU, Apple MPS, and Jetson, and can be launched locally, through Docker, or via hosted Colab, Kaggle, and Hugging Face notebooks.
