  Offline audiobook from any format with one CLI command2024 · github.com · ▲105

  QuickPiperAudiobook locally generates an mp3 audiobook on Linux with one easy command. It can convert PDFs, epub, mobi, and many more by using ebook-convert. It uses any piper TTS model, and thus supports a wide variety of languages. I've had great success using it to read more while reducing eye strain and computer usage. I think I've probably read 30 or so books this way now over the past year. Being able to listen to any content you want in audio form free and offline while going for a walk is extremely handy. I hope it helps you as well! Cheers
