audiblez

Audiblez converts EPUB e-books into spoken audio using Kokoro-82M on your computer. It's for readers who want an audiobook version of a book, with control over the voice and which sections get read aloud.

• Audiobook files: Create a complete M4B audiobook and separate WAV files for individual chapters.
• Narrator voices: Choose voices for American or British English, Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese and Mandarin Chinese.
• Reading controls: Adjust speech speed and select the chapters or sections to include, with an interactive chapter picker in the command-line tool.
• Graphical interface: Convert books through a graphical app or use the command-line tool.

Audiblez is open source under the MIT license and runs on Windows and macOS. Speech generation uses the CPU by default, with optional NVIDIA GPU acceleration through CUDA and PyTorch. Apple Silicon Macs can run conversion on the CPU, but Apple Silicon GPU acceleration isn't supported.

Conversion can also run on Google Colab with CUDA; that option uses cloud hardware rather than your computer. Local operation requires Python, espeak-ng and FFmpeg.
